Diamond Crystal and Gold in Conglomerate
300 million years old
Diamantina, Minas Gerais, Brazil
Millions of years ago there was a diamondiferous kimberlitic pipe somewhere in Brazil. As the pipe eroded, the diamonds washed into the streams and rivers which later dried up and the material "cemented" together to form a conglomerate of sand, pebbles, stones, gold and diamonds which eventually hardened into rock. The present conglomerate has at least one extruded, large diamond crystal visible and a gold crystal to the reverse side. It is very unusual to find a specimen which has both of these occurrences simultaneously. Measuring 4 x 3 x 2 1/2 in.
