3.5" Spessartine Garnets on Feldspar - China
Here is a beautiful cluster of spessartine garnets that formed from a feldspar matrix, collected from Fujiang, China. Comes with an acrylic display stand.
Feldspars are a group of rock-forming tectosilicate minerals. It is also one of the most common minerals on earth, making up nearly 60% of the crust.
Spessartine, often mistakenly referred to as spessartite, is a nesosilicate, manganese aluminium garnet species with the chemical formyla Mn2+3Al2(SiO4)3. The name is a derivative of Spessart in Bavaria, Germany, the type locality of the mineral.
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.
