A riviere of this magnitude is jewellery at its most distilled and most serious, and this one is exceptional. Fifty-one round-brilliant diamonds run as a single unbroken line in platinum, totalling 100 carats, the colour reaching F — fine white near the top of the scale — with clarity available on request. Platinum, the connoisseur's metal, holds the stones with cool, enduring strength and lets their fire dominate. The mastery of a piece like this lies in matching fifty-one stones so precisely in size, colour and fire that the line reads as one continuous river of light. A 100 carat riviere of this calibre seldom returns to the market once privately held, and its worth endures in tangible, portable form. Equally suited to restraint and to occasion, it is an heirloom of the first rank. Certification is provided on request, with the discreet personal guidance our private clients expect. We invite you to a private viewing in the Negotiation Room, where the necklace and its terms can be examined in complete confidence.
