Sotheby’s to introduce autumn-themed jewelry at September auction

14 september 2017
Sotheby’s will sell a range of nature- and autumn-themed jewelry at its London auction this month, featuring designer brands such as Cartier and Buccellati.
Lots under the hammer at the Fine Jewels sale on September 20 will include a Cartier bracelet from the 1940s designed as a vine, with flowers set with citrines and the leaves featuring single- and circular-cut diamonds. The auctioneer has estimated the piece at $25,900 (GBP 20,000) to $38,800.
The event will also feature a Cartier-signed brooch modeled as a cockatoo, containing carved sapphires, brilliant-cut diamonds and blue enamel, as well as oval rubies for the eyes. It sits on a perch of baguette diamonds. Sotheby’s expects it also to fetch $25,900 to $38,800.
A brooch designed as a bramble branch, also appearing at the auction, features single-cut diamond petals with carved leaves from nephrite and carved berries from other stones. Its price estimate is $3,400 to $4,500.
Other seasonal jewels include a Cazzaniga-signed brooch that looks like ivy climbing up a ladder, and a Buccellati brooch modeled as three acorns and oak leaves.
