This Art Deco solitaire engagement ring features a 0.10 carat old European cut diamond (VS2 clarity, J color) set in a square mounting with milgrain bezel details made of 14 karat white gold. The band includes intricate filigree decorative metalwork and delicate engravings, while an orange blossom motif appears under the gallery for added period-authentic detail. The combination of the old European cut diamond's soft brilliance with the detailed metalwork creates a ring that captures the distinctive style and craftsmanship of the Art Deco era.
