AAA Tanzanite and Diamond Halo Statement Ring in 18k White Gold

This exquisite statement ring features a central 2.9 carat AAA-grade oval-cut tanzanite, characterized by a deep, velvety violet-blue hue with significant saturation. The gemstone is securely held by six white gold prongs. Surrounding the center stone is an elaborate double halo and shoulder design containing approximately 2.10 carats of diamonds. The inner halo consists of small round brilliant-cut diamonds, while the outer halo features a striking radial arrangement of tapered baguette-cut diamonds, creating a sunburst effect. The high-profile gallery and wide tapered shank are also encrusted with pavé-set round diamonds along the edges and baguette-cut diamonds down the center of the band. The entire piece is crafted from 18k white gold, providing a bright, cool backdrop that enhances the brilliance of the stones. The setting sits high on the finger, indicating a contemporary or late 20th-century design style. The craftsmanship appears to be of high quality, with precise diamond setting and symmetrical architecture. Aside from minor surface micro-scratches on the polished underside of the shank consistent with light wear, the ring appears to be in excellent condition with no visible chips to the gemstones or loose settings.

Based on my visual examination of this 18k white gold statement ring, the item is in excellent condition, showing only minor surface wear on the lower shank. The centerpiece is a 2.9 ct tanzanite of AAA caliber, exhibiting the highly sought-after 'velvety' violet-blue saturation with potential red flash, which places it in the top 1% of tanzanite quality. The 2.10 ct diamond weight, featuring a complex arrangement of tapered baguettes and round brilliants, indicates a high-end designer or custom boutique origin. Current market demand for large, investment-grade tanzanite remains strong due to its single-source rarity (Tanzania). Comparables at high-end retailers place similar 18k pieces with 2+ carat center stones and substantial diamond weights in the five-figure range. The architectural 'sunburst' halo adds a significant labor premium to the value. A notable factor impacting value is the 18k gold purity, which is superior to the more common 14k found in mass-market jewelry. Limitations: While the color and clarity appear consistent with AAA grade, a definitive valuation requires an in-person GIA or AGL origin and treatment report to rule out excessive heat treatment or synthetic substitutes. I cannot verify the exact diamond color/clarity grades (assumed VS/G-H for this estimate) without a loupe and master stones. For a full legal appraisal, I would require a microscopic examination of the tanzanite's inclusions and a professional metal acid or XRF test to confirm the 750 gold purity.
