A teardrop cabochon of ruby in zoisite measuring 37.2x24.3mm and weighing 51.5 carats, with a notable balance between the two minerals. The polished surface shows vivid magenta-pink ruby patches covering a substantial portion of the face alongside bright green zoisite, with the dark mineral hornblende adding depth and contrast throughout. The ruby color zones are distributed broadly across the center and upper area, making this one of the more ruby-dominant pieces in the range. Ruby in zoisite is an exclusive Tanzanian mineral combination from the Longido area, where ruby corundum and chrome-bearing green zoisite co-formed in metamorphic conditions found essentially nowhere else on earth. At 37.2x24.3mm and 51.5 carats, this teardrop cabochon is a strong-presence piece for pendant centerpieces, statement jewelry, or lapidary collections. Entirely untreated, preserving the natural three-mineral composition of anyolite.
