Kane Posted July 19, 2017 Share Posted July 19, 2017 18 minutes ago, Kingofthekats said: Is feldspar moonstone? Not always. It very much depends on the lustre of the mineral. From the Wikipedia entry: Geology The most common moonstone is of the mineral adularia, named for an early mining site near Mt. Adular in Switzerland, now the town of St. Gotthard.[3]The plagioclase feldspar oligoclase also produces moonstone specimens. Moonstone is feldspar with a pearly and opalescent schiller.[3][4] An alternative name is hecatolite.[4] Formation Moonstone is composed of two feldspar species, orthoclase and albite. The two species are intermingled. Then, as the newly formed mineral cools, the intergrowth of orthoclase and albite separates into stacked, alternating layers. When light falls between these thin, flat layers, it scatters in many directions producing the phenomenon called adularescence. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
ynot Posted July 19, 2017 Share Posted July 19, 2017 To further what Kane said.... Moonstone, sunstone,amazonite and labradorite are gemstone names and are all feldspars. Labradorite and amazonite are actually recognized as varieties of feldspar. 2 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."
