Jewellery, fine art and rare collectors’ items headline Ewbank’s Winter Fine Auctions next month, kicking off a four-day programme of specialist sales.

The four-day series opens on Wednesday, December 10 at 9.30am with the Jewellery, Watches & Coins auction. Among the leading lots is a vintage Graff diamond bangle, estimated at £4,000 to £6,000.

Stamped Graff on the reverse, the 18ct gold piece has a broad section pave set with round brilliant-cut diamonds, estimated to total 1.56 carats, with twisted gold detail and a concealed clasp with figure-of-eight safety catch. It is offered with its original branded suede pouch.

Another highlight is an antique old cut diamond ring in platinum, set with a single stone estimated at 2.57 carats and valued at £6,000 to £10,000. The diamond is an old mine cut, a hand-finished historic style intended to maximise fire under candlelight, giving the stone a romantic, cushion-like appearance sought after by collectors.

Historical interest is further represented by an Edwardian cat’s eye chrysoberyl and diamond ring, expected to sell for £2,000 to £3,000. The centre is an oval cabochon chrysoberyl noted for its chatoyancy – the ‘cat’s eye’ effect where a band of light appears across the surface.

A diamond and pearl brooch, estimated at £3,000 to £4,000, showcases further Edwardian craftsmanship. In 18ct gold and formed as a chrysanthemum, it uses layers of pear-form pearls to create the petals, with the centre and leaves set with diamonds totalling about 1.30 carats on a textured stem.

Also included is an antique Harlequin gem set bracelet with matching bar brooch, estimated at £1,400 to £2,400. The 18ct gold bracelet is set with three oval cut blue sapphires (the largest estimated at 3.23 carats), a red garnet, an orange-brown zircon, a citrine and paste-set stones, creating a colourful Georgian or early Victorian design.

Completing the main diamond section is a pair of floral earrings set with four old cut diamonds totalling an estimated 1.04 carats. Mounted in 18ct gold and platinum, they carry an estimate of £600 to £900.

Contemporary pieces include three pendants from Italian house Ponte Vecchio Gioielli. They feature animal-inspired designs in high-quality materials, among them a sapphire and diamond-set owl pendant (£400 to £600) and two versions of the Vega design octopus pendant set with rubies, amethysts and brilliant-cut diamonds (estimated between £200 and £700).
