9.70 Ct. Blue Tanzanite from Tanzania

A singular and extraordinary specimen, this transparent blue tanzanite weighs 9.70 carats and is masterfully fashioned into a classic emerald cut, with exact dimensions of 13.50 x 11.34 x 7.75 mm, vivid color intensity, and an excellent polish that invites the eye to linger on its step facets and crystalline clarity. Originating from Tanzania, and gently heat treated to reveal its signature velvety cornflower to deep blue tones, this gem is graded very very slightly included when evaluated at eye level, a clarity that reads as practically eye clean to most connoisseurs and collectors. The emerald cut enhances the stone's architectural beauty, producing a serene and sophisticated play of light that emphasizes both depth and purity of hue, the flat plane of the table offering a window into the stone's inner glow. With only a select number of stones of this size and quality available from a single source, this tanzanite stands apart as an object of rarity, an opportunity to own a substantial and distinguished centerpiece that will define a bespoke creation for years to come.

Imagined as the heart of a custom jewel, this 9.70 carat emerald cut tanzanite adapts with effortless elegance to an array of settings, from the clean precision of a solitaire ring, to the soft romance of a vintage inspired halo, to the bold drama of a three stone composition flanked by tapered baguette diamonds. For a modern statement, consider a tension or bezel setting in platinum or 18k white gold to enhance the cool blue tones, or pair the stone with 18k yellow or rose gold to introduce warm contrast and a timeless, regal allure. Its substantial table and generous depth make it ideal for a cocktail ring or a showpiece pendant designed to hang freely and capture light at every turn, while a low profile bezel can be employed for daily wear, protecting the corners and preserving the gem for generations. Designers will appreciate the stone for channeling the linear elegance of the emerald cut into cufflinks, men s signets, or a dramatic brooch, and for pairing with accent diamonds, white sapphires, or subtle colored melee to either highlight the vivid blue or create a layered palette in bespoke commissions.
