Zoisite

Ca2Al3(Si2O7)(SiO4)O(OH)
Orthorhombic heart IMA grandfathered

Zoisite is a calcium aluminum sorosilicate mineral with the chemical formula Ca2Al3(Si2O7)(SiO4)O(OH). It crystallizes in the orthorhombic crystal system and belongs to the epidote group of minerals. Zoisite has a Mohs hardness of 6.5 and a specific gravity of approximately 3.1 to 3.5. It exhibits a vitreous to pearly luster and is typically found in shades of green, brown, or gray. The mineral is classified as a nesosilicate in the Strunz system (9.BG.10) and in the Dana system as 58.2.1b.1. It is known for its prismatic crystal habit and is often associated with metamorphic and igneous rock formations.

Overview

Zoisite is a calcium aluminum sorosilicate mineral with the chemical formula Ca2Al3(Si2O7)(SiO4)O(OH). It crystallizes in the orthorhombic crystal system and belongs to the epidote group of minerals. Zoisite has a Mohs hardness of 6.5 and a specific gravity of approximately 3.1 to 3.5. It exhibits a vitreous to pearly luster and is typically found in shades of green, brown, or gray. The mineral is classified as a nesosilicate in the Strunz system (9.BG.10) and in the Dana system as 58.2.1b.1. It is known for its prismatic crystal habit and is often associated with metamorphic and igneous rock formations.

Etymology

Zoisite is named after Sigmund Zois, an Austrian mineralogist and nobleman. The mineral was recognized and named in his honor for his contributions to mineralogy.

Geological genesis

Zoisite is a nesosilicate mineral typically formed in metamorphic and igneous environments. It is commonly associated with the alteration of calcium-rich igneous rocks under high-pressure and moderate-temperature conditions.

Spiritual meaning and crystal therapy

Spiritual meaning

Zoisite is traditionally associated with spiritual growth and emotional balance. It is believed to support inner harmony, encourage self-awareness, and aid in the release of negative thought patterns.

Esoteric properties
