A broad oval cabochon showcasing the distinctive two-mineral combination of ruby in zoisite, measuring 38.9x29.4mm and weighing 71.3 carats. The polished face reveals a generous spread of vivid green zoisite matrix with a bold, saturated magenta-pink ruby zone dominating the upper portion of the stone, alongside scattered smaller ruby patches and the dark hornblende mineral inclusions that are characteristic of this Tanzanian rock type. The wide oval form gives the full color composition excellent visibility across its face. Ruby in zoisite, also called anyolite, is found almost exclusively in the Longido area of northern Tanzania, where the two minerals formed together in a metamorphic geological process. This large 71.3ct oval is the largest piece in the range - well suited for display, decorative lapidary work, an oversized pendant centerpiece, or a collector's cabinet piece. The stone is entirely untreated, preserving the natural interplay of its three constituent minerals: zoisite, ruby corundum, and hornblende.
