A Cartier Panthère clock will lead the upcoming Bonhams auction in London, where it could fetch up to GBP 300,000 ($398,292).
The Art Deco-style timepiece from the 1970s features an octagonal rock crystal dial with single-cut diamond hands, in an onyx bezel surround with circular-cut diamond Roman numerals. Two panthers adorned with pavé-set diamonds and onyx flank the dial, while a rough black diamond sits on top of the piece. The clock will go under the hammer at the December 10 Exceptional Jewels, London sale, Bonhams said Monday.
The auction house will also offer colored gemstones, items of notable provenance and jewels from well-known maisons such as Van Cleef & Arpels, Bulgari, and Buccelatti.
Here are some other highlights:
An antique Belle Époque diamond pendant sports a pear-cut, 9.26-carat, D-color, VS1-clarity, type IIa diamond, in a surround of old brilliant-cut diamonds and suspended from a similarly set openwork foliate surmount. The piece formerly belonged to Princess Julia Cantacuzène, Countess Speransky, the granddaughter of the 18th US president, Ulysses S. Grant.
A pair of ear clips from Van Cleef & Arpels, circa 1985, is designed as two flowerheads. The centers contain clusters of brilliant-cut diamonds, with petals featuring calibré-cut rubies.
A ring bearing an old cushion-cut, 5.94-carat Burmese ruby between two brilliant-cut diamonds weighing 1.20 and 1.21 carats.
This Bulgari enamel and diamond necklace from 1970 is designed as a serpent. The jewel features pear-shaped diamond eyes, black enamel, yellow guilloché enamel and brilliant-cut diamond scales.
