This is the riviera in its most classical form, executed without compromise. Fifty-seven graduated round brilliant-cut diamonds, totalling 71.85 carats and graded F in colour, are mounted in platinum to a length of approximately 406mm — a single, perfectly tapered line of light from clasp to centre. The graduation is the achievement here: each stone matched in fire and proportion to its neighbour, the larger diamonds settling at the throat and easing back with quiet precision. It lies flat and luminous against the skin, the most formal of necklaces and yet, in its restraint, the most timeless. A riviera of this matched quality is acquired for generations; assembled parcels of this calibre rarely return to the market once placed. Clarity is available on request, with full certification provided for your review through our private client desk before acquisition. When the moment suits, we would be pleased to arrange a private viewing or to open a quiet conversation about terms in the Negotiation Room.
