Small Cabinet, 7.6 x 5.4 x 4.8 cm
Diamantina, Jequitinhonha valley, Minas Gerais, Southeast Region, Brazil

A rare Brazilian specimen of a gemmy, glassy and lightly frosted, 4 mm, triangular diamond crystal nestled amongst conglomerate river pebbles and cobbles from the Diamantina River of Minas Gerais. These alluvial diamonds, deposited into conglomerates over time, are the reason this region of Brazil was named after an old-time diamond rush. Seldom are such specimens preserved. This one, amazingly, has very prominent pebbles and cobbles on both sides. The diamond rests on a 5.3 cm flat cobble. These came out of Brazil 40-50 years ago.
