AGL Certified 6.29 Carat Unheated Ceylon Cornflower Blue Sapphire with Hearts & Arrows Diamond Platinum Ring

An extraordinary natural sapphire of exceptional size and beauty forms the centerpiece of this one-of-a-kind platinum ring.

At its heart rests a 6.29 carat natural Ceylon cornflower blue sapphire, certified by the American Gemological Laboratories (AGL) and confirmed to be unheated. Measuring 12.56 x 8.19 x 6.28 mm, the sapphire displays the captivating color, brilliance, and rarity that have made fine sapphires among the most sought-after gemstones in the world.

The sapphire is elevated within a custom platinum cathedral mounting and secured by four sculpted iris-leaf prongs, allowing light to enter the stone while emphasizing its graceful oval shape. Flowing crossover ribbons rise from the shank to support the center stone, creating an elegant architectural framework that balances strength with refinement.

Accenting the design are precision-cut Grunberger Hearts & Arrows diamonds. These exceptional diamonds are cut to exacting standards of symmetry and optical performance, producing extraordinary brilliance, fire, and scintillation. Their carefully calibrated sparkle enhances the sapphire without competing for attention, creating a harmonious interplay of light throughout the ring.

Handcrafted in platinum and designed as a future heirloom, this ring reflects the philosophy of Gilded Age Jewelry: exceptional gemstones, enduring design, and uncompromising craftsmanship.
