Ruby in Zoisite Pendants in Sterling Silver  

Natural Ruby Zoisite Set in .925 Sterling Silver

Ruby in zoisite forms when corundum crystals (ruby) grow within a zoisite host rock. The result shows distinctive red and green coloring, sometimes with black hornblende inclusions. Ruby rates 9 on the Mohs hardness scale, while the surrounding zoisite measures 6.5 to 7. This difference means the stone requires settings that protect the softer green areas. The Longido mining district in northern Tanzania remains the primary source for gem-quality ruby in zoisite. Miners extract the material from metamorphic rock formations near Mount Kilimanjaro. The color intensity varies by specimen—some show bold ruby concentrations, others feature subtle pink tones scattered through deeper green zoisite. Our collection includes wire-wrapped designs, bezel settings, and prong-mounted cuts. All pieces use .925 sterling silver, stamped and verified. We have sold natural stone jewelry since 2005 and ship free within the United States. Find a ruby zoisite pendant that fits your price range and style preference.
