Antique Art Deco Platinum 0.81 Ct Old Mine Cut Diamond Ring, GIA Report

A beautiful early 20th-century Art Deco ring crafted in platinum and centered with a 0.81 carat natural Old Mine Cut diamond. The center diamond is accompanied by GIA report #1547767421 and is graded K color and VS1 clarity.

The Old Mine Cut center has the distinctive character prized in antique diamonds, with broad facets and an individual hand-cut appearance that gives the stone a softer, more romantic pattern of light than a modern brilliant cut.

Surrounding the center diamond is wonderfully intricate platinum openwork, set with eight additional Old Mine Cut diamonds of approximately 0.01 carat each, for approximately 0.08 ctw in accent diamonds. These smaller stones are bezel set throughout the pierced and scrolling design, bringing subtle flashes of light into the detailed metalwork without overwhelming the center stone.

The setting continues into beautifully worked shoulders, giving the ring an ornate profile from nearly every angle. At approximately 8.1 × 7.8 mm across the top and 6.7 mm high, it has a substantial presence while retaining the fine, delicate quality associated with period platinum work.

With approximately 0.89 carats total diamond weight, this is an exceptional antique engagement ring that brings together an individually cut Old Mine diamond, intricate platinum craftsmanship, and the unmistakable character of an original early 20th-century jewel.
