Spessartite Composition & Geology
Spessartine commonly occurs within metamorphic rock, and in ultramafic igneous rock formations, granite pegmatite, and low-grade metamorphic phyllites.
Spessartites occur in three basic flavors. There are the light and bright stones, which come from Nigeria, Ramona (CA) and the deeper reddish orange stones that also come from Nigeria.
