Ruby Zoisite (Ruby in Zoisite) is a uniquely occurring natural blend of red ruby and green zoisite crystals with a blend of black hornsblende inclusions only found in Tanzania. It is most frequently cut as a cabochon with attempts made to showcase the fascinating play of the three colors as often as possible. Originating from single source, Ruby in Zoisite is only found in the Longido mining district of Tanzania where it was first discovered in 1954. By 1959 it was determined that there was no large deposit of rubies as originally thought but instead this unusual mottled tri-colored gemstone.
Please enlarge and view the photographs for more detailed views. Shown wet to simulate polish. As with all natural rock, there may be fractures or pits to seal or work around. Each slab has the approximate dimensions listed. I use the longest and widest point and the thinnest, it’s not averaged.
We have worked hard with the lighting and the settings on the camera so that the colors are very accurate. Individual settings may affect color viewing on various devices and I cannot predict what your device will do, but on my Macbook Pro, they’re dead on for color. I appreciate your business!
