An exceptional riviere is the purest test of a diamond house, and this platinum line meets it with fifty-one round-brilliant diamonds graded F in colour and certified by GIA. The stones graduate from a commanding centre down through the line — 100.05 carats in total — each calibrated so the necklace reads as one seamless arc of light around the throat. Platinum, enduring and quietly luminous, gives the piece both its strength and its restraint. This is the calibre of riviere that the most exacting collectors prize for its precision: every diamond matched, every proportion considered. A line of this completeness and certified quality rarely comes to market intact, which underpins both its rarity and its lasting worth. Worn, it is the quiet centrepiece of an evening; kept, it is a true heirloom. Our specialists advise in confidence. Request the GIA documentation and arrange a private viewing in the Negotiation Room, at your own pace.
