About Inderite

Inderite is a hydrated magnesium borate mineral forming colorless to white or pale yellow monoclinic crystals with a vitreous luster in evaporite salt deposits. It was first described from the Inder salt dome in Kazakhstan and also occurs in California's Kramer borate district, USA. Gem-quality facetable material is exceedingly rare and of purely scientific and collector interest; inderite is primarily of economic importance as a borate ore mineral.
