3.1" Spessartine Garnet & Smoky Quartz Association - China

Here is a fantastic 3.1" wide specimen that's composed of pristine spessartine garnets & smoky quartz crystals, on a matrix of feldspar from Fujian Province, China. The garnets display a deep red coloration, with a hint of translucence that can even be observed in dim lighting. There is some very minor chipping to the terminations of the smoky quartz crystals, with one face having a small fracture, likely occurring during the extraction process.

This is a truly gorgeous specimen that would make an excellent addition to any mineral collection. Comes with an acrylic display stand for preferred presentation.

Garnets are nesosilicates having the general formula X3Y2(SiO4)3. There are many species of garnet which include pyrope, almandine, spessartine, uvarovite, andradite and grossular (varieties of which are hessonite, cinnamon-stone and tsavorite). Garnets are found in a wide variety of colors including red, orange, yellow, green, purple, brown, blue, black, pink, and colorless, with reddish shades being the most common.

Silicon Dioxide, also known as SiO2 or Quartz, is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich, hot watery solutions called hydrothermal environments, at temperatures between 100°C and 450°C, and usually under very high pressure. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountains forming, and can be hundreds of millions of years old.

Smoky quartz is a grey-brown to black variety of quartz. This common name is derived from from the appearance of smoke within the quartz crystal. Dependent on the location and the chemicals present during formation, smoky quartz can appear opaque black, however it’s typically translucent to some extent. It’s believed that the quartz gains this color from a combination of natural irradiation and aluminum impurities.
