What are Zoisite and Clinozoisite? Zoisite and clinozoisite are minerals that form during the regional metamorphism and hydrothermal alteration of igneous, metamorphic, and sedimentary rocks. In those environments they are found in massive form and as prismatic crystals in veins that cut schists and marbles. They are also found as crystals in pegmatites that form on the margins of igneous bodies.

The two minerals are dimorphs - they share the same chemical composition but have a different crystal structure. Zoisite is the orthorhombic form of Ca2Al3(SiO4)(Si2O7)O(OH) and clinozoisite is the monoclinic form. The minerals have extremely similar physical properties and can be very difficult to tell apart in hand specimens unless the specimens are well-formed crystals. Clinozoisite forms a solid solution series with the mineral epidote in which iron can substitute for aluminum.

Anyolite Anyolite is a very colorful rock composed mainly of zoisite. It is also known as "ruby in zoisite" because it is composed of green zoisite with bright red ruby crystals, sometimes accompanied by black crystals of the hornblende tschermakite. It is used to produce cabochons, tumbled stones, small sculptures and ornamental objects. Nice pieces of rough material are also sold as specimens.

A material with a similar appearance, "ruby in fuchsite" is often misidentified as ruby in zoisite. Careful testing can easily differentiate these materials because the green fuchsite has a hardness of only 2 to 3, while the green zoisite has a hardness of at least 6. In addition, most specimens of ruby in fuchsite exhibit blue kyanite alteration rims around the ruby crystals, and this does not occur around ruby crystals in zoisite.

Physical Properties of Zoisite and Clinozoisite Zoisite and clinozoisite have the same chemical composition. This gives them very similar physical properties, as shown in the accompanying table. The difference between the two minerals is in their crystal structure. Zoisite is a member of the orthorhombic crystal system, and clinozoisite is monoclinic. They are difficult to tell apart in hand specimen unless well-formed crystals are present. Optical tests and x-ray diffraction are the best ways to make positive identification.
