Dolomite (GEMMY twins) on Quartz

Item Description

A really attractive and showy specimen from Brumado featuring classic, GEMMY, compressed twinned crystals of soft golden color Dolomite with selective alternating WATER CLEAR clarity and matte luster associated with very gemmy prismatic Quartz crystals. There is a dusting of reddish-brown Goethite and greenish "Chlorite" on the piece as well, giving it a great mix of color. The Dolomites are sometimes referred to as "phantom" twins due to their color zoning. 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 in excellent condition overall, and the only imperfections I can see are on the back / base of the piece as the Quartz crystals are incomplete where the piece was removed from the pocket wall. 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 1.8 cm across. Valued at $650.
