Description from the seller

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.
