Exceptional Natural Tanzanite 10.48 ct – IGI Certified – Deep Blue-Violet – Emerald Cut Here is a rare opportunity to acquire a tanzanite of considerable size, from the world’s only deposit (Merelani Hills, Tanzania). Characteristics of this exceptional stone: • Weight: 10.48 carats (highly sought weight – stones over 10 ct are rare) • Dimensions: 14.63 × 10.63 × 6.66 mm • Cut: Emerald cut – elegant proportions that maximize color depth • Color: Deep intense blue-violet (Deep Violetish Blue) – saturated, noble hue highly valued by connoisseurs • Clarity: Transparent Certificate: IGI (International Gemological Institute) no. 821699191 This tanzanite displays a rich, deep color characteristic of the finest qualities. Its emerald-cut perfectly showcases its changing blue-violet reflections with light (pleochroism phenomenon typical of tanzanite). Highlights justifying its value: • Weight over 10 carats (significant threshold on the market) • Saturated, deep color • Independent IGI certificate • Natural origin guaranteed • Standard heat treatment (stable and globally accepted) Tanzanites of this size and color intensity fetch high prices among jewelers and collectors. A rare collectible and investment stone, ideal for a prestige setting or to enrich a gem collection. Delivered with its original IGI certificate. Photos taken under different lighting to faithfully show its true beauty.
