This is a gem, bi-colored Tourmaline from Brazil. It is more pinkish rubellite on one side and more teal-blue indicolite on the other side. There are a dozen different crystals all growing together. The colors are Intense, and there's nothing opaque about it. This is a great piece as a palm-sized, massive example of gem tourmaline from Brazil. It has excellent lustre. I just got this from an estate collection and it comes with its original label form Luis Leite, a famous Portugeuse dealer who passed away in the late 1990's. It weighs a substantial 121 grams! Given it is a "conglomeration," of gem pegmatite tourmaline, there are some broken crystals along with pristine terminated ones.
