Where to find Spessartine
Namibia
Known for producing some of the finest 'mandarin' spessartine garnets, particularly from the Kunene region.
Nigeria
Significant source of high-quality spessartine, often with excellent color and clarity.
Brazil
Found in pegmatites, producing good quality crystals.
Pakistan
Sources of spessartine, often associated with pegmatitic environments.
USA (Virginia, California, Maine)
Localities in the USA have produced spessartine, often in pegmatites or metamorphic rocks.
Myanmar (Burma)
Known for producing spessartine, sometimes in association with other gemstones.
China
Various localities produce spessartine, often in metamorphic or pegmatitic settings.
Collecting tips
- Geological Context. Focus your search in areas known for manganese-rich metamorphic rocks or granitic pegmatites. Consult geological maps for these rock types.
- Associated Minerals. Look for spessartine in association with minerals like quartz, feldspar, muscovite, biotite, tourmaline, and other manganese-bearing minerals.
- Crystal Habit. Spessartine often forms distinct dodecahedral or trapezohedral crystals. Look for these characteristic shapes within the host rock or in alluvial deposits.
- Color Recognition. Its distinctive orange to reddish-orange color is a key identifier. In the field, this color can stand out against lighter matrix rocks.
- Hardness Test. Garnets are relatively hard (6.5-7.5 on Mohs scale). If you have a known quartz sample (hardness 7), spessartine should scratch it or be scratched with difficulty.
