2.28 Ct. Tanzanite from Tanzania

This 2.28 carat cushion shaped violet tanzanite from Tanzania is presented by The Natural Gemstone Company as a technically refined specimen that balances substantial weight and exceptional color performance. The stone measures 8.27 x 6.61 x 5.72 millimeters, and its mixed brilliant cut combines a faceted crown geometry with a brilliant pavilion schema to deliver both controlled light return and scintillation. The clarity is graded as eye clean when evaluated at eye level, and the surface finish is an excellent polish, with crisp facet junctions and uniform facet proportions. The material has been heat treated, which is the standard enhancement used to activate the characteristic blue to violet hues in natural zoisite, and the result in this piece is a stable medium intense violet face up color that sits toward the more violet end of the tanzanite color spectrum. In the context of available material, a cushion shaped tanzanite exceeding two carats, exhibiting a true violet modality rather than predominantly blue, and presenting as eye clean is uncommon, making this specimen rare relative to similar size offerings that more frequently show lighter or bluer tones or contain visible inclusions.

From a faceting and light performance perspective, the mixed brilliant cut on this cushion shape has been executed to emphasize both color saturation and controlled brilliance, a balance that is particularly important for violet tanzanite. The pavilion features modified brilliant facets that encourage internal return of light, creating concentrated flashes of violet and blue as the stone is rotated. The crown facets are proportioned to allow a generous table while maintaining enough crown height to distribute color evenly across the face. With average face dimensions of 7.44 millimeters and a pavilion depth of 5.72 millimeters, the calculated depth ratio is approximately 76.9 percent, which is deeper than the median for many gem cuts, and this depth contributes to enhanced color saturation when viewed face up. For tanzanite, which exhibits strong pleochroism, the mixed facet architecture amplifies the violet channel while still permitting underlying blue flashes on certain axes, so the gem exhibits dynamic color behavior depending on orientation and light source. The excellent polish ensures minimal surface diffusion of light and crisp return from facet planes, enhancing both the perceived color intensity and the fine scintillation expected from a well executed mixed brilliant cut.

Regarding material characteristics and market rarity, tanzanite is typically more available in smaller sizes and often graded toward blue or violetish blue in commercial parcels. True violet tones in clean, larger stones are less frequently encountered because the natural crystallization and subsequent cutting often favor bluer orientations for maximum yield. A 2.28 carat cushion that reads medium intense violet face up, with eye clean clarity and a carefully engineered mixed brilliant facet set, therefore represents a low incidence occurrence in the supply chain. The combination of size, face up color depth, clarity, and workmanship elevates its desirability for collectors and connoisseurs seeking a distinct violet presentation rather than the more common blue dominant pieces. From a practical perspective the material should be set in a protective mounting, as tanzanite has a hardness that warrants cautious daily wear and benefits from bezel or well protected prong settings for rings, while pendants and earrings allow for more exposed displays of the pavilion and crown interplay.

For buyers who prioritize technical attributes, this tanzanite provides a precise specification profile, including weight, dimensional geometry, cut style, clarity assessment, color intensity, polish grade, enhancement disclosure, and geographic origin from Tanzania. The stone is particularly suited to bespoke settings where its slightly deeper pavilion can be used to advantage to deliver a richer face up tone, and where the eye clean clarity will present an unencumbered window into the material. The Natural Gemstone Company stands behind the documented characteristics of this gem, and can provide additional imaging, angle specific photos, and mounting recommendations tailored to preserve the optical and physical integrity of the piece. For those seeking a rare violet tanzanite at a substantial weight with meticulous cutting and finishing, this specimen represents a technically compelling option.
