SPESSARTINE   Outcrop above Ore Hill Mine, Warren, NH
2.8 cm specimen - broken crystal section of orange spessartine with manganese oxide coated outer rim.

Species:           SPESSARTINE
Locality:         Outcrop above Ore Hill Mine, Warren, NH
Specimen Size: 2.8 cm specimen - broken crystal section of orange spessartine with manganese oxide coated outer rim.
