The Black Rembrandt
This 42.27-carat black diamond was featured in Christie's "Magnificent Jewels" of May 19th, 2005 Geneva, lot 101. It is set in a pendant surrounded by a row of brilliant-cut white diamonds. Its name derives from its presentation near the Rijksmuseum in Amsterdam by the Rembrandt specialist Gerry Schwartz. Cut from a rough crystal of 125 carats, the brilliant-cut black diamond took three years and three days to cut due to its extreme hardness and multiple 'grain' directions. This is a fairly common occurence when cutting black diamonds. Its estimate was 50,000 to 70,000 Swiss francs. It sold for 60,000 Swiss francs, or $49,800 US.
