This exceptional necklace from the 1920s captures the sparkling elegance and timeless rarity of the Art Deco era. Measuring approximately 110 cm in length, it is composed of natural round-faceted blue zircons — not to be confused with synthetic zirconia. Each gemstone is individually set in a delicate spectacle (collet) setting, allowing it to move freely and reflect light from every angle, creating a floating, luminous effect.

Good to know:
Blue zircons are among the most brilliant natural gemstones in the world — their strong double refraction gives them a sparkle that rivals even that of diamonds. In the 1920s, they were highly prized as a luxurious choice for women of style and distinction.

The opera length (around 110 cm) was especially fashionable in the 1910s and 1920s, as it could be worn either as a single long strand or doubled for a layered, elegant look. Style icons such as Coco Chanel made this length a symbol of femininity, movement, and modern sophistication.

A fascinating original piece with history — ideal for collectors, vintage enthusiasts, or anyone seeking a dazzling statement of Art Deco refinement.
