Ruby Zoisite Crystals (Tanzania)

Ruby zoisite is a relatively rare stone that's a combination of green zoisite and red corundum.

Crystals of black hornblende may also be present.  Gem grade red corundum is ruby.

These grade B ruby zoisite crystals have a slightly rougher texture.  When gently moved around in ambient lighting minute sparkling crystals can be seensparkling crystals can be seen.  Admittedly you need to catch the light at just the right angle.

Weights and sizes vary slightly from piece to piece but they're a medium sized tumbled stone. We also have grade A ruby zoisite in our collection.  The grade A stones have a richer colour and finer polish but they're not as well included with red corundum. 

Ruby zoisite is also known as ruby in zoisite.  This is a more accurate description of what the stone is.  Although used primarily for decorative purposes it can be difficult to work with because of the difference in hardness between the zoisite and corundum.

Stones are often confused for ruby in fuchsite (fook~site) which has a similar appearance but is not as rare.  The vast majority comes from India whilst ruby zoisite comes almost exclusively from Tanzania.
