A rivière of true period character, this mid-twentieth-century necklace carries the confidence of its era in every link. At its heart sits a circular brilliant-cut diamond of 11.91 carats, a commanding centre stone framed by round and single-cut diamonds and punctuated by round rubies whose warmth plays against the diamonds' cool fire. The result is a study in classic contrast — white brilliance lit by ribbons of red — composed with the hand-craftsmanship that defines fine jewellery of the period. Metal is on request. A rivière of this vintage and balance is the kind of piece collectors hold for decades, prized both for its presence at the throat and for its provenance, and for being a tangible, enduring asset that rarely returns to the market once held. It sits as comfortably with eveningwear today as it did at its making. Certification and full condition details are available on request, and acquisition is handled with complete discretion by our private client team. We invite you to a private viewing in the Negotiation Room to examine the necklace closely and discuss terms in complete confidence.
