8.48 Ct. Violetish Blue Tanzanite from Tanzania

This is an exceptional, transparent 8.48 carat emerald cut tanzanite, measuring 13.20 x 9.33 x 7.36 mm, presenting a vivid violetish blue hue with excellent polish and an eye clean clarity as evaluated at eye level. The emerald cut, with its long, elegant step facets, emphasizes the stone’s color saturation and clarity, giving a broad, luminous table that showcases the gem’s deep, even tone. Originating from Tanzania, this tanzanite has been heat treated, a stable and widely accepted enhancement used to intensify the desirable blue and violet tones. The stone displays classic pleochroism typical of tanzanite, with flashes of both blue and violet visible when the gem is rotated, and the cutter has optimized the orientation to maximize the most attractive face up color. The combination of 8.48 carats in weight, the precise proportions created by the emerald cut, and the vivid color intensity places this specimen well above the typical market offerings where larger sizes often come with paler color or visible inclusions.

For the discerning buyer who understands the factors that command price and prestige, this tanzanite represents a rare convergence of size, color, and clarity that is increasingly difficult to source. Color intensity is the primary driver of value in tanzanite, and vivid violetish blue stones of this scale are materially rarer than smaller gems of similar tone, partly because the supply of top quality rough from Tanzania is finite and concentrated. An eye clean clarity grade at this weight enhances both wearable appeal and long term desirability, while the excellent polish ensures superior light return and a satiny finish to the facets. At The Natural Gemstone Company we prioritize full disclosure, and we recommend independent certification for buyers seeking formal documentation. For practical use we advise protective settings that respect the emerald cut’s step facets and corners, and we can provide bespoke mounting recommendations, detailed imagery, and video inspections on request. This tanzanite is suited to an elegant solitaire or a refined halo design, and for collectors and investors it represents an opportunity to acquire a genuinely rare, well presented example of a premium Tanzanian tanzanite.
