Spessartine Crystal


Spessartine, like other garnets, possesses high refractive index and hardness, making it suitable for use as a gemstone. However, its transparency and clarity can vary, with larger, gem-quality stones being relatively rare. Additionally, unlike some other garnets like pyrope and almandine, Spessartine often lacks strong dispersion (fire), potentially affecting its brilliance.
