(IDEX Online) - A parcel of 1,223 carats of alluvial diamonds from the Lulo mine, in Angola, has sold for $1.9 million.
The Lucapa Diamond Company is exploring hard-rock kimberlite sources in the Canguige tributary catchment area, which hosts some of the world's most valuable alluvial diamonds.
The sale, the second this year, achieved an average price of $1,535 per carat and brings the total revenue so far from Lulo diamonds in 2020 to $5.3 million.
Stream bulk sampling in the area has produced a good white population - including top D-color stones - and some rare Type IIa gems.
