.35 Antique Old Mine Diamond Engagement Ring 18k

This Art Deco era solitaire engagement ring features a .35 carat old mine cut diamond with SI1 clarity and I color, set in prongs made from 18 karat white gold. The square-shaped diamond with rounded corners creates distinctive light reflection patterns typical of old mine cuts. The intricate filigree mounting displays milgrain detailing along the band edges, characteristic of Art Deco craftsmanship from the 1920s and 1930s. The ornate white gold setting provides depth and texture that highlights both the diamond and the period-specific metalwork.
