Diamond from Mbuji-Mayi, DR Congo
Mbuji-Mayi diamond is one of the classic African collector diamonds: not usually the icy, cuttable, octahedral gemstone ideal that dominates jewelry advertising, but a rich family of natural crystals that serious mineral collectors recognize immediately. The most distinctive pieces are sharp to rounded cubic “Congo cube” diamonds, modified by octahedral, dodecahedral, tetrahexahedral, and hexoctahedral faces, often with honey-yellow, amber, greenish-yellow, silvery, grey, beige, or reddish tones. Many are true floaters—complete all around, naturally etched or frosted, and surprisingly sculptural under magnification.
