4.93 Ct. Cabochon Tanzanite from Tanzania

This semi translucent violet tanzanite weighs 4.93 carats and is fashioned into a cushion shaped cabochon measuring 9.85 by 8.74 by 5.97 millimeters. The cabochon cut favors a smooth domed surface that emphasizes the stone's internal depth and color clarity rather than faceted brilliance, and the excellent polish produces clean reflective highlights across the crown. Color intensity is described as medium intense, providing a balanced violet presence that is visually appealing without being overstated. Clarity has been graded as slightly included when evaluated at eye level, with natural internal characteristics that are typical for tanzanite and that contribute to the gem's individual identity. The piece has been heat treated, a standard and widely accepted practice for tanzanite that enhances the blue violet tones and stabilizes the hue, while leaving the natural character of the material intact. Overall the combination of size, cabochon form, and surface quality presents a substantial, wearable specimen that responds well to bezel and closed setting designs where the stone's color and translucence can be appreciated.

The origin of this tanzanite is Tanzania, and that provenance materially contributes to its value and desirability. Gem quality tanzanite is effectively limited to the Merelani district of northern Tanzania, making authenticated Tanzanian origin an important factor in market perception and long term supply considerations. Provenance informs expectations about typical crystal habits, inclusion types, and the routine use of heat enhancement, and it supports transparent valuation aligned with trade standards. For buyers and collectors, a documented Tanzanian source enhances confidence in authenticity and complements the objective details of weight, dimensions, cut, clarity, and polish provided here. The Natural Gemstone Company presents this stone with that provenance in mind, offering a clearly described example of natural tanzanite that reflects both geological rarity and established gemological practice. Whether considered for a bespoke jewelry commission or as part of a curated collection, this Tanzanian cabochon tanzanite stands as a well characterized specimen with verifiable attributes and responsible sourcing.
