.25 Antique Deco Diamond Filigree Engagement Ring 18k

This antique Art Deco 18k white gold engagement ring features a .25-carat old European cut diamond (I color, VS2 clarity) flanked by two single-cut accent diamonds (.015 carats each, 1.5mm). The I color shows warmth with a faint yellow tint visible to the naked eye, while VS2 clarity means any inclusions are invisible without magnification.

The old European cut is an early diamond cutting style from the Art Deco era (1920s-1930s) that creates a different pattern of light return than modern brilliants, with a smaller table and larger facets that produce chunky flashes rather than intense sparkle. The center diamond sits in a four-prong setting. The band features filigree metalwork—delicate openwork patterns created by twisting and curling thin gold threads—that was characteristic of Art Deco design.
