Garnet
Garnets are a group of silicate minerals. All species of garnets possess similar physical properties and crystal forms but differ in chemical composition Such as Pyrope Mg3Al2Si3O12, Almandine Fe3Al2Si3O12, Spessartine Mn3Al2Si3O12, Andradite Ca3Fe2Si3O12, Grossular Ca3Al2Si3O12, Uvarovite Ca3Cr2Si3O12. Most Garnets have a variable magnetic attraction. This characteristic also uses to identify garnet. Pyrope – almandine – […]
