Amethyst drop cut cabochon 43.70
Amethyst drop cut cabochon 43.70
Large semi-transparent Amethyst cabochon, with color zoning and clear cleavage and crystallization planes; which are characteristic of the trapiche variety of this gem. Beautiful color in its non-uniform distribution, which perfectly follows the contours of what in gemological jargon is called "Brazilian Twinning Law"
A collectible gem: a section of a single crystal showing a non-uniform distribution of color. The purple, in fact, is determined by the oxidation state of the iron present in the chemistry of this variety of quartz. An interesting cabochon, which speaks to the formation of this crystal
