AI-assisted summary
Description from the seller
Genuine Mozambique Ruby - 239.30 ct (47.79 g) - Natural, Untreated
In the auction, a magnificent specimen of a ruby crystal of considerable size and weight, a full 239.30 Ct. Mozambique is renowned worldwide for producing some of the finest rubies on the market, and this crystal embodies its geological essence. The piece displays the typical and fascinating structure of corundum, enriched by natural inclusions and small dark matrix spots that certify its authenticity and mineral provenance. As visible in the images, when placed against a light source (torch/backlight), the ruby reveals extraordinary fluorescence and a vibrant red-magenta translucence. The complete absence of heat treatments or glass fillings (glass-filled) makes this mineral a true rarity, ideal for exclusive mineral and rough gem collections, a long-term investment in 100% natural material, with potential for cutting or artistic shaping by expert lapidaries.
