Spessartite - Yellowish Orange Garnet 

Spessartite is an orange to red-brown gemstone that belongs to the large and varied garnet species. The name, "spessartine" comes from the Bavarian word, "Spessart", meaning "forest", which is a mountain range in Germany where spessartine garnet deposits were found in the 1880s. Spessartite was not often seen in jewellery until deposits were mined in Namibia and Mozambique in the 1990s.
Spessartite has manganese in its formula. This manganese creates a yellowish-orange color. Because many of spessartite’s ancestors married almandines, many are a reddish orange due to some iron. The lighter orange spessartites, similar in color to orange soft drinks, are almost pure spessartites.
