Tiffany and Co. Platinum Round Diamond Engagement Ring

Centered by a GIA-graded round brilliant-cut diamond, this platinum engagement ring showcases the classic 57–58 facet arrangement engineered for balanced brightness, fire, and scintillation. The diamond’s round geometry is paired with a platinum mount, providing a naturally white, high-strength setting that optimizes light return and long-term durability. A contemporary 21st-century piece signed Tiffany & Co., the ring reflects precision craftsmanship with clean, refined finishing and exacting tolerances typical of the house. Platinum construction offers superior wear resistance and a secure presentation for the round brilliant center stone—an enduring, technically sophisticated choice for a lifetime piece.
