About Tremolite
A calcium magnesium amphibole, often white, grey, or pale green, forming bladed or fibrous crystals (some forms are asbestos). It's a stone of serenity and high spiritual connection, reducing stress. (Handle fibrous forms with care).
Primary Hues
White, Grey, Green, Pink, Lilac, Brown, Colorless, often forms bladed, fibrous (asbestos form: handle with care), or prismatic crystals
Geological & Scientific Details
Tremolite is classified as a inosilicates mineral which typically crystallizes in the monoclinic system. Its chemical formula is Ca2(Mg5.0-4.5Fe2+0.0-0.5)Si8O22(OH)2. Common crystal habits include elongated prismatic, or flattened crystals; also as fibrous, granular or columnar aggregates.
