.50 Antique Deco European Diamond Engagement Ring 18k

This antique Art Deco engagement ring in 18 karat white gold holds a .50 carat Old European cut center diamond flanked by two diamond accents totaling .05 carats (.025 each), for a total weight of .55 carats.

The center diamond has G color, meaning it appears colorless with no visible yellow tint, and VS1 clarity means any inclusions are extremely difficult to spot even under magnification—representing exceptional quality.

Old European cuts were hand-cut in the late 1800s and early 1900s with smaller tables and larger facets than modern brilliant cuts, creating chunkier flashes of light rather than the scattered sparkle of contemporary diamonds.

The four-prong setting allows maximum light to enter the stone while the filigree mounting adds the delicate metalwork typical of Art Deco design. The band features chevron engraving—a V-shaped pattern that creates geometric lines characteristic of 1920s-1930s jewelry.
