The riviera is the purest of necklaces, and this one states its case in clean geometry. Fifty carats of cut-cornered square modified brilliant diamonds — the principal stones at 4.01, 3.21 and 3.13 carats — run in a single graduated line, set in platinum that keeps the whole cool and uninterrupted. The cut-cornered square shape gives each stone a crisp, architectural edge while the modified brilliant faceting keeps the fire alive, a balance of precision and brightness that rewards close attention. It lies flat and luminous on the collarbone, formal enough for the grandest evening yet wearable in a way few statement necklaces manage. A matched riviera of this calibre is acquired for permanence; parcels of this consistency rarely return to the market intact. Colour and clarity are available on request, with full certification provided for your review through our private client service before acquisition. When you are ready, we would be glad to arrange a private viewing or to open terms in the Negotiation Room.
