6.79 Ct. Tanzanite from Tanzania

This 6.79 carat round violet tanzanite presents exacting dimensions of 11.60 by 11.60 by 7.53 millimeters, executed in a mixed brilliant cut that marries the luminous scintillation of a brilliant facet arrangement with the color concentrating depth of modified pavilion faceting. The mixed brilliant silhouette uses a precisely proportioned brilliant crown to generate crisp, high contrast facet reflections, while the pavilion incorporates elongated facets that concentrate and saturate the stone core. The geometry has been optimized for tanzanite specific optical behavior, with facet angles selected to balance light return and color saturation, and a table plane dimensioning that preserves intense tone without inducing windowing. The round outline is true and concentric, demonstrating meticulous symmetry control across the girdle circumference. Facet junctions are clean and sharp, surface transitions are faithful to the intended facet architecture, and the excellent polish elevates each plane to a mirror finish that maximizes light transmission and internal reflection. These cut and finish choices are intentionally calibrated to exploit the gemological properties of tanzanite while maintaining a substantial face up presence appropriate to a 6.79 carat weight.

Clarity and internal character play a central role in the visual performance of this tanzanite, the clarity grade is very very slightly included evaluated at eye level, and as such the stone exhibits an effectively pristine appearance to typical viewing. Inclusions are minute, well isolated, and positioned in locations that do not interrupt major facet junctions or interfere with the pathway of light through the core of the gem. The result is a stone that behaves as though it were practically flawless under normal inspection, with no visible obstructions to brilliance or scintillation. That near imperceptible internal condition allows the mixed brilliant faceting to operate without disruption, delivering uniform flash and scintillation across the crown, and a deep, saturated color when viewed face up. From pavilion to table, the precise facet arrays create consistent light return and a fine balance between brilliance and fire, so that every turn of the gem reveals a controlled sequence of reflections and flashes, each one emphasizing the violet hue and maintaining visual integrity from every angle.

Color and treatment are correlated to both provenance and craftsmanship, this tanzanite shows intense color intensity that occupies the desirable violet range, inheriting the material character of its Tanzanian origin. Tanzanite exhibits pleochroism and requires considered cutting to orient the trichroic axes for the most favorable visible color, here the cutter has oriented the material to maximize the violet channel while preserving depth across the pavilion to avoid a skeletal or washed appearance. The gem has undergone stable heat treatment to optimize the violet saturation, a standard enhancement applied to tanzanite that converts initial brownish or greenish components into the characteristic violet blue, and it has been executed with controlled thermal profiles to maintain crystal integrity and natural character. Craftsmanship practices include precise girdle finishing to ensure secure setting possibilities, consistency of facet angles for repeatable optical performance, and a high quality polish that reveals undistorted facet reflections. The overall presentation is one of refinement and technical exactitude, making this piece an exemplary specimen for connoisseurs who value both gemological integrity and visual impact.

The Natural Gemstone Company endorses this tanzanite as a superb technical execution of material, its substantial 6.79 carat weight combined with exacting proportions, very very slightly included clarity when evaluated at eye level, intense color intensity, excellent polish and considered heat enhancement results in a gem that reads as virtually flawless to the naked eye and that rewards close examination with consistent, high quality optical behavior. For buyers who appreciate fine detailing in faceting styles, clarity grading implications, and provenance informed color optimization, this violet tanzanite offers both the empirical data and the aesthetic outcome that justify its selection for a significant piece of jewelry.
