art deco diamond, onyx, and platinum line brooch


The Story

Made during the Art Deco era, circa 1930s-1950s, this antique brooch is a lovely unisex accent to any outfit. Done in platinum, the long piece is filled with stones. At center is a gorgeous Old European cut diamond weighing approximately 0.35 carats. Bezel set with millegrain detailing, 8 calibré-cut onyx stones surround the diamond. Moving out from the center are 14 half-moon onyx pieces with 70 rose cuts diamonds measuring 1.25 mm each accenting the striking stones. 

The design and stone combination is quintessentially Art Deco. Measuring 2 inches wide, it's a great piece to add to any look or to wear as a chic hair accessory.
