Helvite, Quartz (Var: Smoky Quartz), Feldspar Group
Wushan Spessartine Mine, Tongbei, Yunxiao Co., Zhangzhou Prefecture, Fujian Province, China
Miniature, 4.3 x 3.3 x 2.5 cm
A lustrous, partially gemmy, zoned golden-yellow helvite crystal set on feldspar matrix with glassy smoky quartz crystals from recent finds at the Tongbei area of China. The 9 mm x 9 mm, sharp tetragonal crystal has interesting beveled edges. A rich sprinkling of tiny muscovites are a very nice accent. Helvite is a rare manganese, beryllium silicate and this is a very fine combination specimen from this well-known locale, known more for its super spessartine garnets.
