Antique Style Blue Tanzanite Ring 6.39 Ct., 18K Yellow Gold

This ring is centered with a transparent cushion shaped blue tanzanite weighing 6.39 carats, with precise dimensions of 10.43 by 10.43 by 7.83 millimeters, cut in a mixed brilliant style to balance depth and surface scintillation. The stone exhibits vivid color saturation and an excellent polish, qualities that contribute to its lively blue to violet blue appearance. Clarity has been assessed as very very slightly included at eye level, providing visual purity while remaining a natural, untreated example of Tanzanian origin. The cushion outline and mixed brilliant faceting create a substantial visual presence on the finger, presenting a combination of fire, dispersion, and broad color that is characteristic of high quality tanzanite from its source region.

Complementing the center stone is a halo and shoulder configuration of natural white round diamonds, applied to enhance brilliance and frame the tanzanite. A small cluster of accent diamonds, totaling approximately 0.036 carats, have been graded as Very Slightly Included in clarity categories VS1 and VS2, with a color grade of F. A second grouping of white round diamonds, totaling approximately 0.504 carats, has clarity graded as VS and a color grade of F to G. The combined accent diamond weight is approximately 0.540 carats, selected for consistent white balance and clarity, and set to support a uniform halo appearance and measured sparkle around the central gem. The entire composition is executed in solid 18 karat yellow gold, offering a warm contrast to the tanzanite and a durable mounting medium for everyday wear.

Security of the gemstone setting is a primary consideration in the design and fabrication, and the ring is constructed to provide long term stability and peace of mind. The center tanzanite is held with four robust prongs, positioned to secure the corners of the cushion shape while allowing light to enter the pavilion, a balance between protection and optimal presentation. The halo diamonds are set in a closely applied bead or shared prong arrangement that minimizes movement, while the shoulder diamonds are integrated into the shank with secure settings to reduce the risk of loss. The gallery and understructure are reinforced with a supportive framework of 18 karat gold, transferring mechanical stresses away from the stones and into the metal, and the shank is continuously formed with a solid cross section to resist bending. All settings are finished and polished to remove sharp edges that can catch, and the prongs are properly formed and tipped to clinch the gem girdle effectively. Routine inspection recommendations include a professional check at least once a year and additional evaluation after any notable impact, and we advise insurance coverage for loss or damage as an additional safeguard.

Provenance and finish are fully documented in the construction and presentation of this piece, and The Natural Gemstone Company has specified origin, cutting, and grading details to ensure transparency. The tanzanite is identified as originating from Tanzania, showing the expected hue and saturation profile of material from this region. The mixed brilliant cut and excellent polish demonstrate attention to lapidary technique, and the accent diamonds are selected to complement the center stone without overpowering it. Care instructions include gentle cleaning with warm soapy water and a soft brush, avoidance of harsh chemicals and ultrasonic cleaning if the ring will be subjected to impact or significant thermal shock, and secure storage when not worn. This ring combines significant gemstone quality with considered jewelry engineering to deliver an object that is both visually compelling and constructed for reliable wear.
