8.81 Ct. Violet Cabochon Tanzanite from Tanzania

This translucent violet tanzanite weighs 8.81 carats and measures 14.18 by 9.39 by 7.08 millimeters, presented in an oval cabochon profile that emphasizes color saturation and internal character. Cut as a cabochon, the dome-shaped top and carefully formed girdle reduce edge stress and present a uniform color field, while the excellent polish delivers a clean surface luster and smooth tactile finish. Clarity is graded included at eye level, with visible internal features that add depth and three dimensionality rather than distracting from the gem, and the intense color intensity is a direct result of both the material quality and the standard heat treatment applied to enhance the characteristic blue violet hues. Origin is Tanzania, and the specimen displays the strong pleochroism typical of tanzanite, with shifts between blue and violet when the stone is rotated, a property that interacts favorably with the cabochon cut to produce a lively, saturated appearance under ambient light.

From a durability and daily wear perspective this tanzanite performs well when set and maintained with its material properties in mind. Tanzanite, a blue violet variety of zoisite, has a Mohs hardness of approximately 6.5 to 7, and has distinct parting or cleavage tendencies that can affect toughness, so impact resistance is moderate rather than high. The cabochon form reduces the vulnerability associated with sharp facets and corners, and the excellent polish further minimizes surface abrasion, making the stone suitable for regular use in jewelry where protective design is applied. For rings, I recommend a full or partial bezel, recessed gallery, or protective shoulder design to shield the girdle and pavilion from knocks. Pendants and earrings are especially practical choices for daily wear because they lower the risk of lateral impact. Clean the stone with warm soapy water and a soft brush, avoid ultrasonic and steam cleaners, and keep the gem away from strong acids and prolonged thermal shock. The heat treatment is stable and permanent, and with a conscientious setting and routine care this cabochon tanzanite will retain its intense color and polished surface for years. This piece is offered by The Natural Gemstone Company, and our team can advise on mounting options that preserve both the beauty and the long term durability of this fine Tanzanian cabochon.
