Diamond crystal in Conglomerate (rare)

Item Description

A 6 mm, glassy, striated, triangular, tabular diamond crystal is nicely nestled in a large, dramatic and sculptural, very poorly sorted pebble-cobble conglomerate from the famous Diamantina River of Minas Gerais. The large cobble at the bottom is 4.8 cm. 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, for obvious reasons! This one, amazingly, has very prominent pebbles and cobbles on both sides! For overall aesthetics, this one is about the best we have offered at auction. These came out of Brazil 40-50 years ago. Valued $2000
