Rare Art Deco Hexagonal Filigree Ring with Grey Agate & Diamond

A rare and beautifully preserved example of Art Deco design, this hexagonal filigree ring dates to circa 1925 and is crafted in 14k white gold. The elongated geometric face centers on a softly colored grey agate, cut to follow the mounting's distinctive hexagonal outline. Its translucent grey tone gives the ring an understated, almost ethereal quality while providing a striking backdrop for the crisp white gold details.

At the center of the agate rests an approximately .20 carat old European cut natural diamond, set within a contrasting diamond-shaped white gold frame. The diamond is graded approximately I1 clarity and I-J color, offering the softer brilliance characteristic of antique-cut stones. Fine milgrain edging and delicate engraved details frame both the center diamond and the perimeter of the agate, while intricate filigree continues along the shoulders for an exceptionally detailed finish from every angle.

The strong geometry, delicate metalwork, and use of contrasting materials are wonderfully characteristic of the Art Deco period, yet the unusual grey agate makes this example particularly distinctive. Its elongated silhouette creates elegant coverage on the finger without feeling overly heavy, while the neutral palette makes it surprisingly versatile for an antique statement ring. For collectors of unusual Deco jewelry, the combination of grey agate, an old European cut diamond, and intricate white gold craftsmanship gives this piece exceptional character.
