An elegant antique diamond ring from the Art Deco era, crafted in 14K white gold and rich with finely detailed period workmanship.

At the center is a sparkling old cut diamond (approximately 3 mm, ~0.10 carat), set in a beautifully sculpted buttercup-style head. The stone displays the soft, romantic brilliance characteristic of early diamonds, with broader facets that differ from modern cuts.

The shoulders are especially striking, featuring delicate hand engraving, milgrain edges, and small accent diamonds set within heart-like motifs—an uncommon and charming detail that adds to the ring’s antique character.

The openwork gallery beneath the center stone further reflects early 20th-century craftsmanship and gives the piece a light, refined profile.
