A Chopard Happy Diamonds necklace in 18K yellow gold, a pavé-set drop pendant holding free-moving diamonds, with a baguette diamond and a triangular ruby.

The Piece

Chopard was founded in Sonvilier in 1860 by Louis-Ulysse Chopard. Its Happy Diamonds line, introduced in 1976, lets loose diamonds move freely behind clear crystal.

A pear-shaped pendant holds several loose diamonds that shift as the wearer moves, framed by a border of pavé-set diamonds. A baguette-cut diamond sits at the top and a triangular ruby at the base, and the heavy curb chain closes with a box clasp stamped with the maker's name and the 750 gold mark. The maker refinished the exterior in July 2026.

The chain is 42 cm (16.5 in) long, the pendant measures 43.4 mm by 26.0 mm (1.71 by 1.02 in), and the necklace weighs 80.8 g (2.85 oz). The outer box, the inner box and the maker's repair statement and guarantee are included; both boxes are soiled.

Authenticity & Care

Season stamps, plate engravings, clasps and plating are examined together and documented in Japan before dispatch. Every piece carries the Japonista authenticity guarantee. Keep it boxed or in a soft pouch away from perfume and hairspray, and wipe with a soft dry cloth only; never use metal polish on plated finishes.

Delivery from Japan

Packed by hand in Japan and shipped insured and tracked by EMS or an equivalent express service. Import duties and taxes, where applicable, are payable on arrival. Every sale is final; please ask anything before you buy, and see our published policy.

Length and width are measured by hand, in centimetres, and a chain falls differently on every neck. Lay a chain you already wear along a tape measure and allow a little margin, the quiet safeguard on a final sale. Our necklace length chart shows each length from 40 to 75 cm as it is worn, and for anything it leaves open the curator team replies within one Tokyo business day.
