55 cts Oval, Round Lab Grown Diamonds 18k White Gold Necklace

There is a reason the diamond rivière necklace has belonged to the most iconic moments in jewellery history. This one carries 55 carats of oval and round diamonds in E-G colour and VVS-VS clarity, graduating in size from the back of the neck to a generous centre stone that anchors the whole piece at the décolletage. The oval cuts are particularly well chosen here — their elongated shape creates a continuous, almost liquid line of light across the collarbone. At 37.5 cm, it sits precisely where it should, close enough to the neck to feel substantial, open enough to move with the wearer.
