Spessartine, sometimes mistakenly referred to as spessartite,, manganese species, Mn2+3Al2(SiO4)3. The mineral spessartine should not be confused with a type of igneous rock) called spessartite.
Spessartine's name is a derivative of Spessart in Bavaria of the mineral. pegmatite and allied rock types and in certain low-grade metamorphic phyllites, India , Madagascar, Mozambique and the United States Spessartine of an orange -yellow has been called Mandarin garnet and is found in Madagascar. Violet-red spessartines are found in rhyolites in Colorado. In Madagascar, spessartines are exploited either in their bedrock or in alluvium. The orange garnets result from sodium-rich pegmatites. Spessartines are found in bedrock in the highlands in the Sahatany valley. Those in alluvium are generally found in southern Madagascar or in the Maevatanana
Spessartine forms a solid solution series with the garnet species almandine Well-formed crystals from this series, varying in color from very dark-red to bright yellow-orange, were found in Latinka, Rhodope Mountains , Kardzhali Province Spessartine, like the other garnets, always occurs as a blend with other species. Gems with high spessartine content tend toward a light orange hue, while almandine prevalence induces red or brownish hues.
