RAPAPORT... Lucapa Diamond Company has recovered a 129.58-carat rough
diamond at its Lulo mine in Angola — the eighth stone above 100 carats since
production started at the deposit in August 2015.
Testing on a Yehuda color machine showed the diamond was
type IIa, D-color, Lucapa said Monday. The company also found a 78.61-carat
diamond with those same specifications, it added.
Lucapa is currently attempting to find the kimberlite from
which these large diamonds originated. The present Lulo deposit is an alluvial
mine, meaning the diamonds located there have been washed away from their
source.
“Explosive and erosive geological forces have deposited
these very rare and valuable diamonds in a relatively localized area at Lulo,”
said Stephen Wetherall, managing director of Lucapa. “These localized
recoveries, and other indicators, point to the huge potential of a large-stone
primary kimberlite source at Lulo.”
The largest rough diamond found at Lulo to date was the
404-carat 4th February Stone, which Swiss jeweler De Grisogono cut into an
emerald-cut, 163.41-carat, D-color, flawless polished stone. The luxury group
expects the jewel, set in a necklace or a bracelet, to fetch an amount in the
region of $30 million to $40 million at a Christie’s auction in Geneva on
Tuesday.
