Frequently Asked Questions
No, it is a mineral specimen of interest to collectors and researchers, but it is not used as a gemstone due to its softness and rarity in suitable forms.
It derives from 'kermes', referring to the insect Kermes vermilio used to produce a crimson dye, due to the mineral's similar red colour.
No, it is a relatively rare mineral found in specific antimony deposits, such as those in Germany, France, Peru, and Algeria.
Its chemical formula is Sb₂S₂O (antimony(III) oxysulfide).
