2.24 Ct. Violetish Blue Tanzanite from Tanzania

This 2.24 carat round violetish blue tanzanite from Tanzania presents exceptional technical and aesthetic qualities, offered by The Natural Gemstone Company. The gem measures 8.15 x 8.09 x 4.91 mm, producing a depth percentage of approximately 60 percent, a proportion that balances light return and color saturation for face up appeal. The cutter chose a mixed brilliant strategy, combining a brilliant style crown with a modified pavilion geometry, to optimize scintillation and maintain strong color concentration. Clarity is graded very very slightly included at eye level, indicating inclusions are minimal and do not interfere with light transmission, while the polish is excellent, yielding crisp facet junctions and unobstructed facet reflections. This tanzanite is heat treated, a standard enhancement that reduces brownish zoning and accentuates the vivid blue violet palette that tanzanite is prized for. Optical parameters inherent to tanzanite, including a refractive index in the high 1.60s and modest birefringence, contribute to broad, velvety flashes of color rather than the highly fragmented fire seen in higher dispersion gems.

In direct comparison to more common blue gemstones, this piece stands apart for its combination of vivid color and pleochroic behavior. Compared with blue sapphire, which often exhibits higher refractive index and crisper white sparkles, this tanzanite emphasizes saturated violet blue tones and larger, more ribbon like flashes of color due to pleochroism and the mixed cut. Versus blue topaz and blue spinel, which typically present lighter tones or more uniform blues, this tanzanite demonstrates deeper saturation and a dynamic shift in hue when tilted, an effect that appeals to connoisseurs seeking movement in color. Compared to diamond, dispersion is lower, so fire is more restrained, however the stone compensates with intense body color and targeted facet planning that produces strong contrast and scintillation, making it an eye catching center stone. For designers and collectors, the 2.24 carat round offers a versatile platform for prong and halo settings, where the excellent polish and precise facet alignment will maximize the stone for both daylight and artificial illumination. The Natural Gemstone Company presents this tanzanite as a technically refined example of modern cutting and traditional material quality, a specimen that will reward careful setting and discerning wear.
