MID-20TH CENTURY DIAMOND AND RUBY RIVIÈRE NECKLACE Circular brilliant-cut diamond of 11.91 carats, round and single-cut
Provenance and presence meet in this mid-twentieth-century riviera, built around a circular brilliant-cut diamond of 11.91 carats. Smaller round and single-cut diamonds carry the line to either side, punctuated by round rubies whose red lends the white brilliance a glow of warmth and character that a wholly colourless piece would lack. A centre stone of nearly twelve carats is a rare survivor at this age, and the period craftsmanship lends the necklace a quiet authority no new piece can imitate — the patina of genuine hand-work that collectors of old jewellery prize above all. Metal, colour and clarity are confirmed on request, with full documentation provided to clients who advance. A vintage riviera of this calibre is parted with reluctantly and seldom returns to the market, holding its worth across generations as both occasion piece and heirloom. Pieces with this combination of scale, age and condition are genuinely scarce, which is precisely what makes them enduring. Our specialists offer discreet, candid guidance throughout, never pressing toward a decision. To examine the necklace in person and discuss terms in confidence, we welcome you to a private viewing in the Negotiation Room.
