The rivière is the purest expression of the diamond necklace, and few reach this height. Fifty-one round brilliant-cut diamonds, individually GIA certified between 2021 and 2024, graduate from 6.02 down to 1.00 carat for a total of 100.05 carats — every stone D colour, Flawless, Type IIa, with excellent cut, polish and symmetry. Set in platinum, the line is calibrated so each diamond meets the next in a seamless arc of light, a feat of matching that connoisseurs of precision will immediately understand. Stones of D-Flawless, Type IIa purity at this weight are among the rarest in the world and seldom assembled as a single, harmonious whole. It wears with effortless poise and holds its worth as a tangible, enduring asset. Full certification accompanies the necklace, presented in confidence to qualified collectors. We invite you to arrange a private viewing, or to open terms discreetly in the Negotiation Room at your convenience.
