GARNET VAR. SPESSARTINE
Wushan Spessartine Mine
Tongbei, Yunxiao Co.
Fujian Province, China

Miniature
2 x 1.5 x 2 Inches
5 x 3.5 x 5.5 Centimeters

A small specimen of very densely packed spessartine garnets that grabs your attention with their gemmy sparkles - There is hundreds if not thousands of bright orange crystal faces that dance in the light when you "rock" the piece in your hand. The Wushan mine is no longer operating and these specimens are considered Chinese classics!

Garnet is the name used for a large group of rock-forming minerals. These minerals share a common crystal structure and a generalized chemical composition of X3Y2(SiO4)3.

These minerals are found throughout the world in metamorphic, igneous, and sedimentary rocks. Most garnet found near Earth's surface forms when a sedimentary rock with a high aluminum content, such as shale, is subjected to heat and pressure intense enough to produce schist or gneiss. Garnet is also found in the rocks of contact metamorphism, subsurface magma chambers, lava flows, deep-source volcanic eruptions, and the soils and sediments formed when garnet-bearing rocks are weathered and eroded.

The most commonly encountered minerals in the garnet group include almandine, pyrope, spessartine, andradite, grossular, and uvarovite. They all have a vitreous luster, a transparent-to-translucent diaphaneity, a brittle tenacity, and a lack of cleavage. They can be found as individual crystals, stream-worn pebbles, granular aggregates, and massive occurrences.

Calcium garnets typically form when argillaceous limestone is altered into marble by contact metamorphism along the edges of igneous intrusions. These are andradite, grossular, and uvarovite, the slightly softer, typically green garnets with a lower specific gravity. Two calcium garnets are highly regarded in the gem trade; they are tsavorite (a bright green grossular) and demantoid (a golden-green andradite).

Spessartine is an orange garnet found as crystals in granite pegmatites.
