A piece of exceptional rarity and importance — a signed and numbered vintage collar necklace by Cartier, crafted in 18ct yellow gold. At its centre sits a luminous cabochon sapphire of approximately 3.15 carats, framed by diamond-set terminals of exceptional brilliance. Diamond-accented links extend on either side, creating a composition of understated opulence that is unmistakably Cartier in its restraint and precision.

Bearing Cartier's signature and individual numbering, this piece carries full authentication of its provenance. At 97.4g in 18ct gold, it has the substantial, heirloom quality that defines the finest mid-20th century Cartier jewellery. Secured by a discreet tongue and box clasp, it sits beautifully at the collar — a necklace designed to be worn, admired, and passed down.

Signed Cartier pieces of this calibre rarely appear on the open market. An extraordinary acquisition.
