A riviere is the truest test of a collector's stones, a line that hides nothing, and this one answers at the highest level. Fifty-one round brilliant-cut diamonds, each independently certified and graded over 2021 to 2024, run from 6.02 down to 1.00 carat for a total of 100.05 carats, every stone D colour, Flawless clarity, with excellent cut, polish and symmetry and classified as Type IIa, the most chemically pure category of diamond. Assembling a perfectly graduated line at D-Flawless, Type IIa, across fifty-one stones is exceptional even at the rarest end of the market, and such a piece almost never returns once privately held. It lies as a single unbroken ribbon of light against the skin, faultless by day and commanding by evening. The full set of independent laboratory reports accompanies the necklace, with discreet personal guidance throughout. We invite you to a private viewing to examine the stones and certificates, and to discuss terms in confidence within the Negotiation Room.
