GEM SILICA CABOCHON (PERU) – APPROX. 14 X 10 MM. OVAL

“Gem Silica” is the term of art for beautiful translucent chalcedony colored by copper minerals, usually chrysocolla. The colors can be arresting and the chalcedony is much harder and far more durable in jewelry than actual chrysocolla itself. Made popular by finds at now-depleted copper mines in the U.S., Peru is currently producing some good stones. This one is slightly varied in color, displaying traceries of green malachite within the darker blue-green chrysocolla/chalcedony. It’s very attractive and hard enough (7 to 7.5 Mohs) for both men’s and women’s jewelry. Calibrated to 14 x 10 mm. this high-domed stone has a slightly curved bottom and a glistening all-over polish. It has proper girdle angles for easy setting and will fit most 14 x 10 standard mountings. No treatment of any kind. (All uses, N)
