Fifteen Favorites from Bonhams California Jewels Sale

Bonhams CA Jewels

The million dollar lots in this season’s jewelry auctions are not the only jewels worth highlighting, oftentimes the low estimate pieces happen to be the most fun – and accessible. Bonhams California Jewels sale focuses on exactly that, affordable vintage jewels that appeal to everyone.

Most of the lots in the sale are from the 20th century with a few pieces from the 19th and 21st centuries. There are fabulous signed pieces from names you know – Cartier, Tiffany & Co., Bulgari and the like – and maybe a few you don’t, such as Barbara Anton, Cazzaniga, and Denise Robergé.
