Item Description

A really attractive and interesting specimen from Brumado featuring classic compressed twinned crystals of soft golden color Dolomite with selective alternating WATER CLEAR clarity and matte luster associated with optic-grade GEM rhombs of colorless Magnesite. Great quality, especially from the standpoint of the Dolomite, as the species is rarely seen in such well-formed twins, let alone GEM crystals. The piece is not 100% perfect (it's contacted on the back) but this is FINE quality twinned Dolomite, and the best of these pieces are some of the biggest and gemmiest twinned specimens from any world locality. The largest Dolomite measures 1.7 cm and the largest Magnesite measures 1.4 cm. .
