Composition of Ruby Zoisite
Calcium aluminum silicate is the combination that produces this green and red gemstone, and it has a specific gravity of 3.35, with a refractive index of 1.35. The ruby inclusions in the stone are of the opaque variety, and can be found throughout the base stone. It is related to tanzanite, which is the blue variety of zoisite.
Where is Ruby Zoisite Formed
Although the first specimen of zoisite was found in Carinthia, most of both ruby zoisite and tanzanite come from Tanzania, Kenya, and Norway. There are sources found around the world, however, ranging from India to the United States. The mineral is formed in both metamorphic and pegmatitic rock.
Jewelry Industry Uses for Ruby Zoisite
Ruby zoisite is one of the most difficult stones to work with, as the ruby inclusions are much harder than the surrounding zoisite. It is used in jewelry of all shapes and sizes, beads galore, and is sometimes called anyolite. The duality in colors gives it a unique design element to use in all forms of art.
History of Ruby Zoisite
Ruby zoisite was first discovered in 1805 in Austria, when a mineral dealer named Simon Prešer brought it to a scientist for identification. It didn't take Sigmund Zois long to realize that he had a new discovery on his hand - and thus zoisite was found.
Folklore Use of Ruby Zoisite
Ruby zoisite does not have the history that many other gemstones has - however, there are a few reported uses of the stone in folklore. The ruby part of the stone is valued for much the same attributes that plain rubies are known for - healing, courage, love, and nobility. It is also known to help elevate energy levels. The green of the zoisite acts as a balancing and dampening element to the ruby's power.
