Scheelite on muscovite
description: <p style="text-align: justify;">LOCALITY: Mount Xuebaoding, Ping Wu county, Sichuan province, China <br /><br />This relatively remote mineral locality produced the finest and most important specimens of scheelite on earth. This locality produced the largest and finest scheelite crystals found anywhere. The orange scheelite crystals from Sichuan are large, colorful, lustrous and sometimes on an attractive muscovite matrix and sometimes with other mineral species including cassiterite, aquamarine or fluorite. The other localities that produced orange scheelite crystals only produces specimens that were 5% or less of the general quality of this fine piece. The other localities that produced orange scheelite included Nundle, New South Wales, Australia; Skardu, Pakistan; The Traversella Mine, Traversella, Chiusella Valley, Canavese District, Torino Province, Piedmont, Italy; The Tenkergin Mine, Iul'tinskiy Mining Complex, Chukotskii Autonomou Okrug, Far Eastern Region, Russia; The Comstock Lode Mine (also known as Cohen Mine, Cohen Tungsten Mine and Adams Mine), Teviston District, Dos Cabezas Mountains, Cochise County, Arizona; Smith Vein, Carrock Mine, Caldbeck Fells, Cumberland, Cumbria, England; Morro Velho Gold Mine, Nova Lima, Minas Gerais, Brazil; The Gamsberg Region, Namibia and Santa Cruz, Mun. de Santa Cruz, Sonora, Mexico. Interestingly, before Sichuan started to produce fine scheelite crystals in the 1990's, scheelite crystals from The Tae Hwa Mine, Korea were considered to include the best of species.  Tae Hwa is no longer considered to be the best scheelite locality on the planet because it only produced brown crystals that were not nearly attractive as the orange crystals from Sichuan.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Traits that make this particular Sichuan scheelite better than thousands of other Sichuan scheelite specimens are as follows:  </p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">(1) The reverse sides of the scheelite crystals are not contacted or damaged.  This perfection (shown in the second photo in the album) is an important upside of this specimen.  Most Sichuan scheelite specimens exhibit two display sides like this one does.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">(2) The scheelite crystals are presented on a contrasting and attractive matrix of crystallized undamaged muscovite with an attractive silvery patina.  Many lesser quality Sichuan scheelite specimens possess either no matrix or only ugly matrix. </p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Photo by <a href="http://www.irocks.com">www.irocks.com</a>  </p>
