1.88 Ct. Violetish Blue Tanzanite from Tanzania

This transparent 1.88 carat cushion shape tanzanite measures 8.45 x 6.44 x 4.21 mm, and presents a meticulously faceted silhouette that balances face up size with depth for optimum light performance. The cutting style is faceted, employing a mixed brilliant cut architecture that combines a faceted crown with a pavilion geometry designed to deliver controlled brilliance and rich color saturation. The cutter has optimized facet planes and junctions to reduce windowing and promote even color distribution across the table, while the excellent polish ensures crisp facet reflections and strong luster. Clarity is graded as eye clean when evaluated at eye level, which allows full appreciation of the intense violetish blue hue without distraction from visible inclusions, and the overall transparency is notable for a tanzanite of this weight and profile.

Color is the defining attribute of this specimen, described precisely as violetish blue with intense color intensity, and the mixed brilliant cut has been selected to emphasize that particular balance of violet and blue. Tanzanite displays strong pleochroism, and this stone shows a dominant violet blue face up, with subtle shifting toward deeper blue within certain viewing angles, consistent with high quality material from Tanzania. The material has been heat treated, a standard and stable enhancement for tanzanite, which converts brownish or greenish undertones into the desirable blue violet range, enhancing hue uniformity and saturation. In controlled lighting the stone exhibits lively color performance, producing vivid flashes of violet along the crown facets and a steady deep blue when viewed through the pavilion, a behavior that will reward both daylight and warmer light sources.

The mixed brilliant cutting approach on this cushion outline combines a series of small, well aligned crown facets with a pavilion that alternates larger and smaller facets to create optical contrast and scintillation. Precision in facet angles and symmetry is evident in the even return of light across the table and in the absence of pronounced dark zones, indicating careful preform planning and conscientious cutter execution. The girdle proportions, as represented by the sidelength measurements and visible profile, provide a stable mounting platform for jewelry fabrication, while the pavilion depth near 4.21 mm supports the stone’s intense color by maintaining sufficient light path length. The excellent polish contributes to minimal surface abrasion, ensuring that facet junctions remain crisp and that the stone will present with a glassy, mirror like finish under close inspection.

Clarity is eye clean at typical viewing distances, which permits versatile design choices without concern for obscuring features, and it also means that light transmission is high, supporting both brilliance and color saturation. Because the specimen is heat treated, the most common microscopic features associated with tanzanite are subdued, leaving only fine internal characteristics that do not affect structural integrity or visual appeal. For mounting recommendations, a protective setting is advisable due to tanzanite’s relative hardness and cleavage tendencies, selecting a bezel or partially bezel set design for frequent wear, or a well engineered prong mount with a secure seat and shoulder protection for ring applications. The dimensions and cushion outline make this gem particularly suitable for a classic solitaire ring, a sophisticated pendant, or a tailored three stone configuration where side stones can be chosen to either complement the violet blue hue with white diamonds, or to harmonize using warm toned accent gems.

The romantic provenance of this stone is intimately bound to its color and origin, a violetish blue that evokes the first dusk over the Mererani hills of Tanzania, where minerals born of geological pressure and long cooling find their way to light. Imagine a twilight exchange, where the sapphire tone of the sky and the last violet breath of the sun are captured in a single gem, offered as an emblem of promises made at sunset. In that imagined scene, the eye clean clarity acts as a window to honest emotion, allowing the wearer to carry an unclouded memory of vows and a landscape that inspired them. The Natural Gemstone Company presents this tanzanite not only as a calibrated technical specimen, but as a piece of that story, a stone that carries both the measured qualities valued by connoisseurs and the poetic resonance desired by romantics, a balance that makes it an heirloom quality choice for those who appreciate both precision and sentiment.
