Stokesite

CaSn[Si3O9] * 2H2O
Orthorhombic heart IMA grandfathered

Stokesite is a rare hydrated calcium tin silicate mineral with the chemical formula CaSn[Si3O9] * 2H2O. It crystallizes in the orthorhombic system and is classified within the Strunz system as 9.DM.05. The mineral exhibits a Mohs hardness of 6, a moderate density, and a vitreous to pearly luster. It typically appears white to pale green in color. Stokesite is a member of the inosilicate group, characterized by single chains of silica tetrahedra. Due to its rarity and specific chemical composition, it is primarily of interest to mineral collectors and researchers.

Overview

Stokesite is a rare hydrated calcium tin silicate mineral with the chemical formula CaSn[Si3O9] * 2H2O. It crystallizes in the orthorhombic system and is classified within the Strunz system as 9.DM.05. The mineral exhibits a Mohs hardness of 6, a moderate density, and a vitreous to pearly luster. It typically appears white to pale green in color. Stokesite is a member of the inosilicate group, characterized by single chains of silica tetrahedra. Due to its rarity and specific chemical composition, it is primarily of interest to mineral collectors and researchers.

Etymology

Stokesite is named after Sir George Stokes, 1st Baronet, a British physicist and mathematician. The mineral was named in his honor, though no specific year of discovery is provided in the facts.

How to recognize it

Stokesite can be identified by its Mohs hardness of 6, which allows it to scratch glass but not quartz. It typically exhibits a white to pale green color and a vitreous to pearly luster. The mineral has a moderate density and may leave a white streak when tested. Due to its rarity, it is often confused with other silicate minerals, but its specific chemical composition and crystal system help in differentiation.

Trivia

Stokesite is notable for its unique chemical composition, which includes both calcium and tin, making it chemically unusual among silicates. It is a rare mineral, with only a few known localities worldwide. Its classification in the inosilicate group, combined with its hydration, adds to its scientific interest as a mineralogical curiosity.

Indicative prices

Stokesite is a rare mineral and is not commonly used in the gem or jewelry trade. As such, it has limited commercial availability. Indicative prices for high-quality stokesite specimens may range from EUR 50 to EUR 200 or more, depending on origin, clarity, and aesthetics.
