Exquisite Art Deco Blue Zircon Necklace

A true jewel of the Art Deco era, this breathtaking necklace features two vivid natural blue zircons, renowned for their exceptional brilliance and unmistakable beauty. These are natural gemstones, not to be confused with synthetic zirconia — genuine treasures of the earth.

Crafted in 15k white gold, the design showcases sparkling old-cut diamond accents, delicate millegrain detailing, and a fine 40 cm (16") chain that sits gracefully just below the collarbone. Blue zircon, the birthstone of December, is celebrated for its rare luminosity and timeless elegance.

A refined and radiant masterpiece of early 20th-century craftsmanship — a perfect union of sophistication, rarity, and history.
