The riviere, a continuous line of diamonds set to flow like a river of light, is among the most timeless of all necklaces, and this one carries roughly 20 carats of round brilliant diamonds in a single, graceful sweep. Round brilliants are cut to return the maximum fire and scintillation, and gathered in this number they create an uninterrupted shimmer that flatters every neckline and moves effortlessly from day to evening. There is a reason the riviere has endured for generations: it is the quiet, versatile cornerstone a serious wardrobe is built around, never ostentatious, always assured. Necklaces of this matched calibre are the work of careful selection and hold their worth reliably, a tangible, enduring asset as much as a classic to pass forward. Colour and clarity are confirmed on request, with certification on request and the discreet guidance of our private client team throughout. We would be glad to arrange a private viewing, where the full report and terms may be reviewed in confidence.
