This Art Deco solitaire engagement ring features a .15 carat old European cut diamond with J color and SI1 clarity, set in a hexagon-shaped head made from 18 karat white gold. The diamond sits within a filigree mounting that displays the intricate metalwork characteristic of the Art Deco era from the 1920s-1930s. The band tapers toward the center stone, creating a graceful transition to the geometric head design. The old European cut reflects the hand-cutting techniques popular during the early 20th century, producing a different light pattern than modern brilliant cuts.
