5-carat pink diamond


A rare, 5-carat pink diamond was auctioned off for a record $10.8 million in Hong Kong on Tuesday, putting some shine back into the world's rare and large stones market which was badly hit by the financial crisis.

The stone, of a "vivid pink" hue and considered near perfect, but not quite flawless, triggered brisk bidding in Christie's autumn sales of Asian and Chinese art in Hong Kong.

"No stone has ever been sold for $2 million a carat, we were used to ... a million dollars a carat for colored diamonds but never 2 million,"

The stone, set in a so-called "cushion-cut" ring by famed jewelers Graff Diamonds, was just a quarter the size of the Geneva stone and not quite flawless but the stone's "vivid pink" is considered near perfect.

While the South African-mined diamond isn't quite rated flawless given minor blemishes, Christie's said that these could be removed by minor repolishing.

Diamond in the bluff

A WOMAN paid $2200 for a diamond ring from GraysOnline, but it was later revalued at just $100 after it was discovered to be a low-grade industrial diamond treated and filled to mask flaws.
Newly engaged Shelley Wang heard GraysOnline sold diamonds cheaper than retail outlets.
When she logged on and saw a 1.07-carat, solitaire brilliant cut engagement ring, the valuation certificate putting the ring's value at $8050 convinced her to bid.
``I saw the certificate online and thought it was legitimate,'' she said.
Ms Wang bid up to $2259 and ``won''.
``Obviously I was excited. I had an $8000 ring that I paid just $2200 for,'' she said.
The cost was immediately billed to her credit card, but when the ring arrived two days later, Ms Wang was horrified.
``The diamond wasn't sparkling, you could see all the little cracks inside it. A piece of glass would have been better,'' she said.
When Ms Wang took the ring to the Diamond Certification Laboratory Australia for grading and assessment, her fears were confirmed.
``It was a low-quality industrial diamond called a reject and worth only $100,'' DCLA's Michael Cohen said.
``There is a treatment called fracture filling, where diamonds are injected under high pressure to fill in and mask faults, much like how they fix a chipped windscreen.''
Ms Wang complained to GraysOnline, and after an internal investigation was reimbursed.
``We found the stone in question was fracture filled and incorrectly described and the valuation was incorrect. A mistake was made, which is why we provided a full refund,'' Mark Kehoe, from GraysOnline said. He said the company only sold on behalf of wholesalers.
GraysOnline sold $700,000 worth of diamond jewellery a month, Mr Kehoe said.
``We engage third-party valuers, a panel from the National Council of Jewellery Valuers,'' he said.
``We rely on a description provided by the valuer.''
Ms Wang's diamond was accompanied by a certificate certified by a registered valuer and NCJV member.
``My understanding is it was impossible to see the fracture fill as it was still in the setting,'' Mr Kehoe said, defending the valuer.
NCJV president Graham Easy said the association had ``a number of complaints'' from consumers who had bought from GraysOnline.
Laboratories could take a low-grade stone and make it look better, which Mr Easy said was ``fine'' if there was full disclosure.
``The problem is with overseas sellers not disclosing the treatments because you cannot see fracture filling with the naked eye,'' he said.
GraysOnline said it no longer sold ``treated diamonds''. It has also stopped advertising that consumers can ``expect to save over 50 per cent on the finest diamonds''.

Synthetic Diamonds on the market in Australia?




A synthetic diamond has been identified by the DCLA, on the heels of the recent discovery of numerous treated diamonds in Australia.
The man-made diamond, a near-colourless 0.54ct round brilliant cut diamond, was submitted to the DCLA Laboratory for authentication by an Australian diamond merchant unconfident of its origin.
With subsequent examination, the diamond was identified by the DCLA as a diamond created by a company in Canada, Advanced Optical Technologies Corporation (AOTC). Identifying features of this diamond include no fluorescence and a light blue hue, as well as a tiny dark grey inclusion with metallic lustre, pictured above at high resolution 50X magnification.
AOTC produces synthetic coloured diamonds (primarily yellows and blues) as well as colourless “white” diamonds using a high-pressure high-temperature (HPHT) process. There are several other overseas companies also producing synthetic diamonds on a wide scale using this process, while others use a newer process using chemical vapour deposition (CVD) technology. To date, however, there has been no fully disclosed importer of synthetic diamonds in Australia.
In terms of identification, synthetic diamonds (also known as man-made diamonds, lab- or laboratory-created diamonds, and lab- or laboratory-grown diamonds), have the same chemical, physical, and optical properties as natural diamonds do, making them impossible to identify without advanced testing.
Examination with a microscope may sometimes show indicators, or ‘clues’, that a diamond is synthetic, but these are indicators only; neither presence nor absence of these indicators is conclusive. Both natural diamonds and synthetic diamonds may show very similar characteristics, thus advanced testing is required for conclusive identification.
Some visible clues of synthetic diamonds that valuers should be aware of are those of dark grey or black inclusions with a metallic lustre, as seen in this particular HPHT-created diamond, inert fluorescence under long-wave UV light, cloud inclusions, internal or surface graining, stronger short-wave to long-wave fluorescence, phosphorescence, and colour zoning, among others. Natural diamonds will also show these characteristics however, which is why identification of a diamond’s origin requires an educated and trained gemmologist, skilled in handling the necessary equipment in a qualified laboratory.
Buyers and valuers should also be aware that synthetic diamonds created by synthetic diamond producers like AOTC are laser inscribed on the girdle for identification and disclosure purposes, ie. “AOTC CREATED” and should be accompanied by a synthetic diamond report for full and clear disclosure – however, this inscription can be removed and a diamond should always be verified.
DCLA will not issue diamond grading certificates for synthetic diamonds

Blue Diamond fetches Record Price for Gem

26.58 carat rough
7.03 carat polished

A rare natural fancy vivid blue diamond sold for a world record price of almost US$9.5 million (AU$12.2 million) at auction in Geneva this month.

The internally flawless, cushion-shaped diamond weighing 7.03 carat was produced by Petra Diamonds’ historic Cullinan mine in South Africa, well-known for its production of blue diamonds, and for many of the most significant diamonds ever discovered. This record-breaking blue diamond was cut from a 26.58 carat rough diamond discovered in 2008. The final US$1.35 million per carat price established a new record for a fancy vivid blue diamond sold at auction, and has surpassed the world record per carat price for any gemstone sold at auction.

The grading of this diamond was performed by the Gemological Institute of America (GIA), grading it as ‘fancy vivid blue’ in colour and ‘internally flawless’ in clarity – in terms of colour and clarity, this is the top grading that may be achieved for a blue diamond.

The diamond was purchased by a Hong Kong real estate investor, Joseph Lau Luen-Hung, said to be a collector and connoisseur. As the first owner of this diamond, he has exercised his right to name the diamond, known from now as the “Star of Josephine”
Commenting on the sale, Petra Diamonds CEO Johan Dippenaar remarked: “The price achieved at the Sotheby’s auction for this exquisite, internally flawless blue diamond is a world record by value per carat and the highest price to be achieved by a fancy vivid blue diamond, and reflects how incredibly rare and collectable such an important blue diamond is to the connoisseur.

The renowned Cullinan mine continues to captivate the world with spectacular diamonds, building on its legacy as the source of some of the world’s most famous gems. This has been a very successful partnership with Sotheby’s, one of the pre-eminent names in jewellery sales, and has provided the perfect platform to garner international recognition for a gem of this calibre.”
Also commenting was David Bennett, Chairman, Europe & the Middle East, Sotheby’s International Jewellery department: “We are absolutely thrilled with the price achieved for this exceptional stone, which ranks as the highest price ever established for a fancy vivid blue diamond. It has been a real privilege to offer a diamond of this importance as the centrepiece of our sale and we have seen it capture the imagination of collectors around the world – particularly in Hong Kong, New York, London and Geneva, where we have exhibited it over the last few weeks.

It has also been very exciting and rewarding to work so closely with Petra Diamonds and to follow the progress of this remarkable gem over the last few months; from its emergence in its initial rough state, through its various stages of cutting and polishing, to its auction success on the international stage this evening.”

This blue diamond is one of the rarest blue diamonds ever auctioned, and for Sotheby’s ranks among the most significant diamonds ever to be offered for sale.

Buying a diamond from an online seller with out seeing it first. Read this letter before you do.


Michael:

As per conversion between my husband xxxxxx and you this morning, here is how and where I got the ring from.

I bought a 1.07 ct solitaire brilliant cut diamond engagement ring claw set from XXXXXXXX.com.au (ID143333) on 13/05/09.
All products on this website are sold as auction.
In product description, it clearly stated the diamond weight, colour, clarity and total weight. It also attached valuation certificate.
On the certificate, it provided photo, diamond weight, colour, clarity and weight as well as valuation. The certificate is provided by jewellery provider which is XXXXX hand crafted designs.

The bid finished at 4.30pm on 13/05/09 and I got a confirmation letter from XXXXXXXX on the same day, please find attached.
The winning bid was $2259 and the buyers premium is 15% of the winning bid (it was stated on the website), which was $338.85.
I also paid $60 for freight.

They took the money from my credit card and sent me paid invoice by email on the same day. Please find attached.

I got an email regarding delivery details on 14/05/09 and i got the ring on 15/05/09. But the ring was not what i expected at all and I did not believe the ring worth the value that on the certificate and the money I spent.

As the incorrect valuation and certificate I am going to return my product and ask for the money back. In order to avoid same thing happens on other customers, I strongly suggest some actions need to be done.
It will be very much appreciated if you can look into this case and protect this market.

Please contact me on xxxxxxxx or email to xxxxxxxx@msn.com if you need more information.

Below is the contact detail for xxxxxxx.
From Shelley

To Add insult to injury the diamond which was then checked by the DCLA was treated and the treatment was not disclosed as seen on the FGAA qualified valuer on his Valuation Certificate.

THE DCLA DIAMOND EXCHANGE...


EVERYTHING IS CLEARER THE CLOSER YOU GET TO THE SOURCE.


Diamonds Online - Savings or Scam?


Does buying diamonds on the internet offer huge savings? Is it safe? Why does it appear so much cheaper?


The internet has become saturated with online diamond retailers promising unparalleled quality, selection and low prices. But has this been a positive development for consumers and the diamond industry in general? Opinions are clearly divided.


Whilst there are some genuine online retailers providing real value, regrettably the net has become the perfect avenue for selling the “leftovers”. What does this mean?


Through the traditional distribution channel in the trade, reputable diamond merchants and jewellers scrutinise, select and buy the diamonds they sell. This process ensures you as the ultimate buyer get a correctly graded diamond. With most internet retailers, a list of diamonds is received from overseas suppliers and listed on the site. These retailers do not sight the diamonds until you have bought and paid for them. Buying from these online retailers, you are not seeing and buying the diamond, you are relying on the information and advice provided by online-sellers commonly referred to as drop shippers, who haven’t seen the diamonds themselves much less paid for them.


While the internet has brought convenience, increased selection and greater competition, it has also provided the perfect vehicle for selling these “leftovers” - over graded and therefore over valued as well as treated diamonds, some with overseas certificates to lend credibility, that cannot be sold through the accountable traditional channels. Although these diamonds are listed for sale at seemingly fantastically low prices, generally one fact remains true: you get what you pay for. There have been many instances where consumers who have bought diamonds online come in to the lab for verification, only to find they have not received the quality represented.
Remember: Low price doesn’t necessarily mean a good deal.


Both the Government and the Industry bodies are aware of, and looking into these issues, but do not know how to, or even if it is possible to police.


Tips for Safely Buying a Diamond Online


1. Buy from an Australian-based website that has a clear money-back return policy. Buying locally, you have recourse if anything is wrong or if you are not happy with your purchase.
2. In Australia only buy a DCLA-certified diamond. DCLA is the only internationally recognised lab inAustralia, and the only lab worldwide guaranteeing that the stated quality of a DCLA certified diamond is accurate, with a third-party full-replacement Diamond Grading Guarantee. Since the grading is guaranteed, you know you’re comparing apples with apples when comparing DCLA certified diamonds to buy – you can decide on your desired quality then shop around for the best price.


Common Online Buying Issues to be Aware of


BAIT AND SWITCH


Thousands of diamonds listed, little or no diamonds physically in stock or available. We call these “ghost diamonds”. Too often when an enquiry is made, that particular diamond is not available and an alternative is offered.This is an old trick - a diamond is listed at a great price, making real jewellers look expensive, but when you want to buy it it’s not available. You will often see terms like “subject to availability” and “Your money will be refunded if we happen to miss the diamond”. “If you wish, we will find a suitable replacement.”


What should you do? Ask if the diamond is in stock and available for you to view. If not, shop elsewhere.


DROP SHIPPING


Many online sellers simply list diamonds from overseas suppliers that they have never seen before. Once you, the customer, buy and pay for the diamond, it is then imported intoAustralia.


What should you do? Ask. Is the diamond available to view before you buy it? If not, shop elsewhere.


EXAGERATED GRADES


Many diamonds listed on the net are either not certified or have “in house” reports or valuations allowing grades to be exaggerated and treatments to be hidden.
What should you do? Only accept a certificate from a respected independent diamond grading lab and make sure the diamond is laser inscribed for identification. This helps ensure that you receive the diamond you bought and paid for. Only compare prices of diamonds with proper certificates. Don’t be fooled by official-looking certificates or valuations from local "gemmologists". They are probably not independent and exaggerate the grades to make the prices look good.


If you would like help finding your diamond, or have further questions, please contact us on 1300 66 3252 (DCLA) and we will be happy to assist.

Growing Incidence of Undisclosed Treated Diamonds in Australia


DCLA has seen an alarming increase in the number of treated diamonds being submitted as natural diamonds to the laboratory for certification.


It should first be said that diamond treatments are neither good, nor intrinsically bad in and of themselves. There is nothing wrong with buying a treated diamond, provided that the treatment is fully disclosed and that you pay the appropriate price for the diamond. Because of their lower cost and value, treated diamonds can allow a person to buy a diamond that appears to be of a higher quality than it truly is.


However, too often the presence of such diamond treatments is concealed. Whether this deception is by intent or negligence, such concealment is tantamount to fraud.


Not only does artificially treating a diamond significantly reduce its value, but most diamond treatments are unstable and reversible. For this reason, all internationally accepted rules for diamond grading forbid the certification of treated diamonds. An extremely disturbing discovery just recently in the DCLA Laboratory was that of a coated diamond accompanied by a certificate from a supposedly legitimate Australian ‘laboratory’.


Members of the diamond industry have a responsibility to consumers to convey accurate and transparent information, and each individual that handles a diamond as it moves down the diamond pipeline from the mines should be held accountable for making known any treatments that a diamond has undergone.


It is deceptive and unfair to fail to disclose treatment of a diamond when it has a significant effect on a diamond’s value. In its pursuit of consumer protection, DCLA is offering a ‘Diamond Amnesty’ for diamond owners Australia-wide – any diamond brought in with its matching diamond grading certificate will be verified for grading accuracy and tested to ensure that it is natural and free of treatments. This service will be provided free of charge.

DCLA identifies Treated Pink Diamond


Recently, a pink coloured diamond weighing 0.70ct was submitted to DCLA laboratory for certification and colour authentication. The colour was described as 3 PP on a diamond report issued by another Australian-based laboratory.


After routine examination however, DCLA discovered that when the diamond is viewed under high magnification with reflected diffused light, a patchy iridescent coating is visible on the surface. This coating is also easily visible on the pavilion facets of the diamond when viewed through the table.


However, when the diamond is observed under magnification with regular diffused light, the pink coloration appears evenly distributed, particularly when viewed face up.


The pink colour is the result of a coating rather than from natural lattice defects in natural pink diamonds. Surface coating is the process of adding a thin layer of coloured foreign material to all or part of a gemstone's surface, with the intent of either masking the underlying body colour or enhancing a desirable colour. Most often, this coating is applied to the pavilion and/or girdle of the diamond; the way that light refracts as it passes through a diamond creates the illusion of uniform colour distribution.


The durability of diamond coatings vary considerably, depending on materials used and methods of coating applied. Most recent advances in technology employ a very thin optical or chemical film which is more durable than older methods, but still readily worn away by heat, scratching, abrasion, polishing, and just everyday wear.


Coating is a deceptive practice; we do not know the number of coated pink diamonds which have entered the marketplace, but the DCLA has seen a number of treated stones of late. Of particular concern is when such treated diamonds are accompanied by seemingly legitimate reports or paperwork.


DCLA screens every diamond submitted to the laboratory for all known treatments, and will not issue a diamond certificate for treated or synthetic diamonds.

Special Valentine Diamond Laser Inscription


Cold Laser Inscription adds a timeless message to your diamond, as an expression of your love.


Laser inscription is the use of a very fine, precise laser beam to write a grading report number or customised personal message on the girdle (outside perimeter) of a diamond, which can be done even if the diamond is set in a ring or other piece of diamond jewellery. The laser inscription on the diamond is totally invisible to the naked eye and can only be seen with a magnifying loupe. It does not change the colour or clarity grade of a diamond and is considered permanent as it can only be removed by a professional diamond cutter.


The DCLA uses the latest cold laser technology that allows excellent control during inscription without damaging the diamond (unlike a hot laser).


The inscription takes only five minutes, and the message lasts a lifetime. Both loose diamonds, and most diamonds set in diamond rings may be be laser inscribed.


Sample messages:


I LOVE YOU ALWAYSMARRY MEJane & John 14/02/09
Certification of the diamond is not required for inscribing a personal message, any diamond may be inscribed. Several fonts are available, and a special Valentine offer is valid from now until the end of February.


For more information, please contact the DCLA at info@dcla.com.au.

DCLA Offers New Damage Assessment and Recut Service


DCLA now offers a precise recut assessment service on poorly finished, chipped, broken, and otherwise damaged diamonds.


The popular belief is that diamonds are indestructable, but the fact is that diamonds can, and do in fact break, chip, or endure other such damage like abrasions and bruising. In most cases, the damage is repairable; DCLA has advanced equipment and specialised software to provide a comprehensive damage assessment report, and recut analysis, on damaged diamonds.



On request, DCLA will have the diamond recut or polished. This service is available to the trade, members of the public, and insurers requiring salvage assessment.

New! DCLA Transparency Grading System


After analysing thousands of diamonds, DCLA has developed a new Transparency grading system, independent of other quality grades listed on the traditional diamond certificate.
Transparency is the degree to which a material transmits light, directly relevant to the cloudiness or haziness of the material.


Diamonds of any clarity, fluorescence and cut can in fact have Very Good or Excellent Transparency, making them attractive stones. Diamonds of any clarity, fluorescence and cut can also have Good or Medium Transparency - light return can be interrupted by multiple features of a given diamond.


The DCLA Transparency Grading System will now take all of these features into account to provide an even more comprehensive assessment of a diamond.


DCLA Transparency Scale:


Excellent - Completely transparent, no light interruption, no haze or cloud

Very Good - Transparent, minimal light interruption, very light haze or cloud, difficult to detectGood - Transparent, slight visible haze or cloud, detectable

Medium - Semi-Transparent, marked light interruption, moderate haze or cloud, easy to detect

Poor - Semi-Transparent, very little light passes through, heavy haze or cloud


Effective September 15 2008, all DCLA Diamond Certificates will include the diamond transparency.


In addition, the DCLA has also split the traditional Finish grade on our Diamond Certificate into the dual features of Polish and Symmetry. This will provide a fuller, more detailed expression of the overall diamond make to both consumers and the trade.

RapNet to list DCLA graded diamonds


The Diamond Certification Laboratory of Australia (DCLA) is proud to announce that RapNet, the World's largest diamond trading network, will now include DCLA certified diamonds in its global listings.

The DCLA Difference


The Diamond Certification Laboratory of Australia (DCLA) is an independent diamond grading and certification laboratory, providing diamond grading certificates, or diamond grading reports, for natural diamonds. The DCLA is one of a growing number of diamond grading laboratories worldwide grading to the International Diamond Council (IDC) rules, (WorldFed Newsletter, Edition 6, August 2003, Page 8). The IDC is the governing body established by the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA). These two bodies are the worlds highest Authorities in Diamonds.
DCLA is the only CIBJO Diamond Grading laboratory for Australia and holds the only official registered National Diamond Masterset for Australia, the C2Au set.


Protecting Diamond Buyers


The DCLA Diamond Grading Laboratory Certificate sets the standard for technical ability. The laboratory is equipped with the most advanced equipment in Australia. All diamonds graded are checked and tested to ensure that they have not been treated and are of natural origin. Therefore the DCLA Diamond Grading Certificate assures the owner that the diamond is free of all known diamond treatments and enhancements. It also confirms that the diamond is natural and not a synthetic diamond. DCLA cold laser inscription links the diamond to the certificate providing added confidence.


Independence means that the DCLA Diamond Grading and Certification Laboratory is autonomous from all diamond and jewellery businesses. The DCLA Laboratory receives no grants or funding from the diamond or jewellery trade, it is completely self funded.


In 1975, The World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (lDMA), appointed a Joint Committee to create an international standard for rules, working methods and nomenclature.


A comprehensive system of rules and methods was built up, combining the practical experience of professional diamond people with scientific facts and figures.


The Committee later changed its name to the International Diamond Council (IDC). In May 1978 the "International Rules For Grading Polished Diamonds" were unanimously approved at the 19th Congress of the World Federation of Diamond Bourses and International Diamond Manufacturers Association. All the major diamonds laboratories have since adopted the system. DCLA is proud to offer a diamond certificate with such pedigree.


The diamond trading floor that gives all diamond buyers direct access to DCLA guaranteed diamonds from Australian diamond dealers.
