This, "rare earth" crystal is from the famous Brazilian emerald deposit. The crystal is lustrous, slightly translucent, and exhibits a rich, dark, cognac color. It also appears to be doubly terminated. This is another species rarely seen in dealers stocks.This is easily one of the best and largest specimens of xenotime around. I have not seen better from this deposit for sale, certainly, for both sizee and for its rich chocolate-golden hue
