1.0kg Ruby in Zoisite Sphere – Vibrant Magenta Corundum – 88mm Description This is a stunning, high-contrast sphere composed of natural Ruby (Corundum) embedded within a vibrant green Zoisite matrix. At over 1kg, this specimen is a substantial example of this classic Tanzanian mineral combination. Mineralogical & Aesthetic Highlights: • Ruby Saturation: The sphere features numerous large, well-defined "islands" of magenta-red Ruby. Under UV light, these inclusions exhibit the characteristic strong red fluorescence of natural Corundum. • Matrix Quality: The surrounding Zoisite is a rich, saturated green, providing the perfect backdrop for the Ruby crystals. • Contrast Elements: Splashes of black Tschermakite (amphibole) are scattered throughout the piece, adding a modern, graphic aesthetic to the natural patterns. • Lapidary Finish: The sphere has been polished to a high-gloss finish, ensuring a smooth, mirror-like surface that highlights the varied textures of the different mineral hardnesses. Natural Geological Features: As an earth-mined mineral, this sphere exhibits unique organic signatures: • Natural Texture: Small, subtle surface pits or "micropores" may be present where the different mineral crystals meet; these are characteristic of genuine Ruby in Zoisite and serve as proof of its natural provenance. • Mineral Growth: The interlocking nature of the Ruby and Zoisite crystals demonstrates the high-pressure metamorphic environment in which this specimen formed. Technical Specifications • Mineral: Ruby in Zoisite (Anyolite) • Weight: 1006g • Diameter: 88mm • Origin: Mundarara Mine, Longido District, Tanzania • Condition: Excellent; high-gloss professional polish.
