Spessartite Is a Gem coloured by Manganese (which gives the orange colour) and iron (which gives reddish or brownish tint) depending on the oxidation state. The chemical structure of Spessartite garnet is Mn2+3Al2 (SiO4)3. And so mostly they appear in brownish yellowish-orange, brownish orange, brown and orange-red hues. This gem is sometimes with the whisky-brown hessonite variety of grossularite garnet. The pure spessartine displays a relatively pure, bright orange colour or mandarin color.
