.25 Antique Art Deco Diamond Cocktail Ring in 14k

This cocktail ring is converted from an antique stick pin and features milgrain filigree detailing with a two-tone metal design. Made from both 14 karat yellow gold and 14 karat white gold, it creates visual interest through the contrast of metal colors. The center stone is a .25 carat Old European cut diamond with I1 clarity and H color grade, secured in a bezel setting. The ring has a navette (elongated oval) shape typical of Art Deco jewelry from the 1920s and early 1930s.

The combination of the Old European cut diamond (a predecessor to today's round brilliant cut) and the detailed metalwork shows techniques commonly used in jewelry before mass production became standard. This piece demonstrates how vintage stick pins were sometimes repurposed into rings to give antique components new life.
