Five stones. Five world records. One rule: a single stone per lot.
No necklaces, no suites, no matched pairs — one stone, and whatever the room was willing to pay for it. Apply that rule to every auction result on record and you get five diamonds. Not one of them is colourless.
Look at places two, three and four. Three different stones, two auction houses, two continents, six years apart — and $264,000 separates all three. At this level the market knows almost exactly what it will pay.
Then there is the number that isn't on the list: $83 million. It still circulates online as the price of the Pink Star, from a 2013 sale that collapsed when the buyer never paid. Sotheby's had guaranteed $60 million and took the diamond onto its own books. Four years later it came back to the room in Hong Kong and sold properly, for $71.2 million, to the chairman of Chow Tai Fook bidding by telephone himself. That is the real record, and it has held ever since.

AN ART DECO BRACELET, CIRCA 1925
Four cabochon emeralds set along a ribbon of close-set diamonds, with a buckle centre of baguette-cut stones framed by open arcs of pavé.
Platinum and 18k gold. 62.5 grams, 18.5 cm. Every link hinged, so the band follows the wrist instead of resting on it. Each diamond seated in its own open collet — which is why the stones take light from behind as readily as from above.
The 1920s turned geometry into luxury. This is that idea worked in metal, at the scale of a wrist.

TOP 6 MOST EXPENSIVE JEWELS EVER SOLD AT AUCTION
The most expensive object ever sold at a jewellery auction was a single diamond. The most expensive piece of jewellery made roughly half as much. That gap is the whole subject of this list.
Strip out the loose stones and the solitaire rings — anything that is one gem with a mount around it — and a different ranking appears. What is left are objects: beads, matched suites, tiaras, historic settings. Six of them, spanning 2011 to 2018.
Sixth, the Donnersmarck tiara: ≈$12.7M at Sotheby's Geneva in 2011, eleven Colombian emerald drops totalling over 500 carats, and still the auction record for a tiara. Fifth, a ruby and diamond necklace by Etcetera: ≈$13.0M at Christie's Hong Kong in 2015, against an estimate of HK$56–88 million. Fourth, the Blue Belle of Asia: ≈$17.6M at Christie's Geneva in 2014, a 392.52 ct untreated Ceylon sapphire that still holds the record for any sapphire.
Third, the Hutton-Mdivani jadeite necklace: ≈$27.4M at Sotheby's Hong Kong in 2014, twenty-seven graduated beads with a Cartier clasp, bought after twenty minutes of bidding by the Cartier Collection itself. Second, The Art of de Grisogono, Creation I: ≈$33.7M at Christie's Geneva in 2017, built around a 163.41 ct D Flawless diamond cut from a 404.20 ct rough found in Angola.
First, Queen Marie Antoinette's pearl: ≈$36.2M at Sotheby's Geneva in 2018. It carried an estimate of CHF 995,000 to 1,900,000 and sold for CHF 36,427,000 — the world record for a pearl. The stone did not change; the documented history behind it did the work.
That is the pattern across all six. Rarity sets the floor. Provenance and paperwork set the ceiling.

CARTIER HERCULES KNOT NECKLACE
A flexible tubogas collar in 18K yellow gold and stainless steel, closing at the front in the Hercules knot — the reef knot the Greeks and Romans wore as a symbol of union and protection, and one of the oldest motifs in jewellery.
Two gold cords loop through one another at the centre, held by an oval citrine in a stepped gold bezel. The warm gold of the stone comes from traces of iron in quartz; against the alternating gold and steel of the collar, it is the single point of colour in the piece.
Signed Cartier on the gold plaque at the junction of the two metals.
