Estate Platinum 5.06CTW Cat's Eye Chrysoberyl Art Deco Ring by Tiffany & Co.

This estate Art Deco ring by Tiffany & Co. is crafted in platinum and set with a 5.06 carat sugarloaf cabochon cat’s eye chrysoberyl measuring approximately 9.27 x 9.08mm. The domed chrysoberyl displays the distinctive luminous band associated with fine cat’s eye gemstones, while the streamlined shoulders feature carved linear detailing characteristic of Art Deco design. The ring weighs 10.4 grams and is stamped Tiffany & Co.

The combination of the bold sugarloaf cut and the glowing cat’s eye effect gives this ring an unmistakable presence that feels both grounded and intriguing. Art Deco jewelry often balances geometry with dramatic gemstones, and this piece does that especially well through its smooth platinum structure and softly shifting light across the chrysoberyl. It has the kind of confident, collected character that works beautifully with tailored black clothing, vintage-inspired styling, or layered alongside other substantial platinum pieces without losing its individuality.

What Makes Cat’s Eye Chrysoberyl Unique?

Cat’s eye chrysoberyl is one of the rarest and most highly regarded phenomenal gemstones. Its defining feature is chatoyancy, an optical effect that creates a narrow band of reflected light moving across the surface of the stone as it shifts. This effect is caused by tiny parallel inclusions or hollow tubes within the gemstone that reflect light in a concentrated line.

The sugarloaf cabochon cut seen in many fine cat’s eye chrysoberyl rings is designed specifically to enhance this phenomenon. Unlike faceted stones that focus on brilliance and sparkle, cabochon cuts emphasize depth, glow, and movement within the gemstone itself. During the Art Deco era, unusual gemstones like chrysoberyl became especially desirable for collectors and luxury houses seeking bold alternatives to more traditional diamond-centered designs.
