RICH BLUE HEMIMORPHITE
Wenshan Mine, Yunnan Province, People's Republic of China
Hemimorphite from the Wenshan (Wen Mountain) Mine often contains enough copper to tint the normally colorless Hemimorphite a rich Robin's Egg blue. Hemimorphite is a zinc silicate with considerable value as an ore of that very useful metal: Zinc. Zinc is used in everything from automobile grilles to the core of the ubiquitous "copper" penny. Viewed from the front, the entire display surface is made up of "bubbles" of radiating, spherical groups of turquoise Hemimorphite densely packed in a single layer. There are a couple of small "bruises" but nothing of any consequence. The back side is a mixture of orange limestone wall rock and Hemimorphite filled fissures. With a custom labeled base, it measures 6 x 6 x 2 inches and is in fine condition.
