7.82 Ct. Cabochon Tanzanite from Tanzania

This is a truly exceptional translucent violet tanzanite, weighing 7.82 carats, offered by The Natural Gemstone Company, and the size alone places this gem firmly in the premium category for tanzanite material. The stone is cut into a cushion shape with cabochon styling, measuring 9.80 by 9.80 by 7.69 millimeters, and the substantial 7.82 carat weight produces a presence and depth of color that is difficult to achieve in smaller stones. For educated buyers, weight in carats is a primary driver of value, and at nearly 8 carats this tanzanite benefits from the economies of rarity that progressively increase per carat value as size grows, especially when combined with vivid color intensity and an excellent polish. The cabochon cut is purposefully chosen for this specimen to maximize the perception of color and translucency, smoothing over internal inclusions while emphasizing the rich violet tone that tanzanite collectors prize.

Clarity is graded as included, evaluated at eye level, which is consistent with many high quality cabochon tanzanites where internal features do not detract from overall visual appeal when the cut and polish are optimized. These included characteristics are visible only upon careful inspection, and they are effectively concealed by the cabochon profile, allowing the vivid color intensity to dominate the visual impression. The gem has been heat treated, a standard and stable enhancement for tanzanite that converts brownish hues into the desirable blue violet tones, and this treatment is fully disclosed. Origin is Tanzania, the only source of gem quality tanzanite, and provenance from this region confirms expected geological signatures and market desirability. The excellent polish ensures strong surface luster and smoothness, which is especially important for cabochon settings intended for pendants and rings where tactile quality matters. For buyers seeking a premium tanzanite, the combination of 7.82 carat weight, vivid color intensity, cushion cabochon form, and Tanzanian origin represents a compelling balance of rarity, aesthetic impact, and market recognition. The Natural Gemstone Company stands behind this description, and we recommend professional certification for investment purchases, along with practical care advice such as avoiding ultrasonic cleaners and harsh chemicals to preserve polish and color integrity over time.
