The name, spessartite or spessartine, is derived from the location of its original discovery in the Spessart Mountains in the Aschaffenburg district of Bavaria, Germany. The color of spessartine garnet ranges from yellow through orange to red, some material appearing brownish. The color prized most highly is an electric orange that is visually stunning. Mandarin garnet is the trade name for this bright orange variety of spessartine.

Color due to manganese Most garnets classified as Spessartine have a small iron content seen here as a weak vague band at 505nm. and a very faint one at 527nm. The darker bands centered at 462nm. and 489nm. are due to manganese and indicate a spessartine garnet. The strong absorption below 445nm. here masks another two lines due to manganese at 432nm. and 412nm

Cat’s-Eye Spessartine Garnet
Cat’s-eye spessartine garnet has a singular light band on the surface of a gemstone created when light encounters hollow tubes, or parallel fibrous, or needle-like, inclusions within its crystal structure. Light that strikes the inclusions within the gem reflects off the inclusions, creating a narrow band of light. One known location is Namibia, but stones have been reported from Brazil and Sri Lanka.
