About Art Deco Jewelry
Art Deco jewelry from the 1930s represents the pinnacle of geometric design and technical craftsmanship, featuring clean lines, symmetrical patterns, and exceptional gemstones. The combination of old-cut diamonds with sapphires reflects the era's fascination with color contrast and bold design. Open-work filigree construction demonstrates the meticulous hand-fabrication techniques of the period, making authentic Art Deco pieces increasingly valuable as both wearable art and historical artifacts.

One of One
Most jewelry is made to be sold many times over. Ours isn't. We source rare vintage and estate watches you won't find in a display case anywhere else, and what we don't source, we make ourselves. Either way, the piece in front of you is singular, not pulled from a production run. When you buy from Assay, chances are no one else on earth owns its twin.

At Assay, we’re proud to be featured as top sellers across multiple marketplaces (1st Dibs, Chrono24, Etsy, Rubylane and more). No matter where you prefer to shop, you’ll find the same exceptional products and service available on every platform!
