A spectacular Graff diamond ring emerged as the star lot at Freeman’s recent Important Jewellery auction in New York, achieving USD $368,800 and surpassing its upper estimate of USD $350,000. The result made it the top-performing lot of the sale.

The auction, held on 11 December, realised a total of USD $4.5 million, with an impressive 91% sell-through rate, underlining continued demand for high-quality signed and gemstone jewellery.

The headline Graff ring features a 13.11-carat oval brilliant-cut diamond, graded H colour, VS1 clarity, flanked by two shield-shaped diamonds weighing approximately 0.95 carats each. The sale also saw strong results for pieces by Bulgari, Tiffany & Co. and Cartier, reinforcing buyer confidence in established luxury maisons.

Commenting on the outcome, April Matteini, Head of Freeman’s Jewellery Department, noted that the final jewellery auction of 2025 delivered a USD $1 million year-on-year increase, marking another milestone in the auction house’s second year at its Upper East Side gallery.
