These grade B ruby zoisite tumbled stones have a slightly rougher texture and minute sparkling crystals can be seen as they catch the light. Weights and sizes vary slightly from piece to piece but they're a medium sized tumbled stone. We also feature grade A ruby zoisite tumbled stones in our collection. These have a richer and deeper colour and are beautifully polished. The downside is they are not as well included with ruby (red corundum).
Ruby zoisite is also known as ruby in zoisite which 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 ruby. 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.
