7.18 Ct. Violetish Blue Tanzanite from Tanzania

This 7.18 carat cushion shaped tanzanite from Tanzania exemplifies why larger, finely cut tanzanites are so highly prized, the gem measures 12.06 by 9.98 by 7.41 millimeters, and displays a vivid violetish blue hue with intense color saturation that reads beautifully face up. The stone is fashioned in a mixed brilliant cut, combining crown facets that maximize scintillation with a pavilion design that preserves depth and color, and the result is a jewel that reads both lively and rich under varied lighting. Clarity is graded as very very slightly included at eye level, meaning that the gem appears transparent and clean to the unaided eye, with only minor internal characteristics that do not detract from brilliance or visual appeal, this level of clarity at over seven carats is uncommon and adds tangible value for a discerning buyer. The polish has been evaluated as excellent, so light returns are crisp and the facet junctions are well executed, qualities that are necessary to elevate a large gemstone into a true statement piece.

From a connoisseurship perspective, this tanzanite’s combination of size, cut, clarity, and color intensity makes it especially well suited for a single stone ring or pendant that commands attention without appearing crude. Heat treatment is a standard and stable enhancement for tanzanite, employed to bring forward the desirable violetish blue tone while retaining the natural character of the mineral, this treatment is disclosed and customary in the trade, and does not diminish the gem’s suitability for everyday wear. Origin from Tanzania situates this stone within the exclusive geographical context associated with tanzanite, an attribute that educated buyers consider when assessing provenance and long term value. At The Natural Gemstone Company we emphasize transparency in grading and presentation, and this piece represents a rare opportunity to acquire a substantial, eye clean, and intensely colored tanzanite that will anchor any bespoke design as a distinguished statement jewel.
