Lucapa Diamond Company recovered six type IIa stones along wtih six other gem-quality diamonds from preliminary surface sampling at its Lulo diamond concession in Angola.
The company noted that the
diamonds were recovered from four separate kimberlite pipes. Five of the
type IIa diamonds recovered weighed a total of 2.30 carats and ranged
in size from 1.05 carats to 0.15 carats. Type IIa diamonds are rare and
account for less than 1 percent of global production.
Kennedy, the managing director of Lucapa, concluded that since
kimberlite pipes at the Lulo concession host type IIa diamonds, this was
another significant milestone for Lucapa.
“The fact we have now
identified several diamond bearing kimberlite pipes proximal to where we
have found large alluvial diamonds is of great significance as we are
really only scratching the surface of these pipes at this time,” he
Kennedy explained that the independent confirmation that 50
percent of the diamonds recovered are type IIa diamonds also adds early
credence that these pipes could be the source of the alluvial diamonds
