International auction house Bonhams is hosting the latest iteration of its California Jewels sale on July 18, at Bonhams’ Los Angeles outpost. Comprising over 320 lots, the auction will include both contemporary and vintage jewels, many of them signed pieces from prominent private estates.

“We are honored to offer important jewels in our forthcoming California Jewels auction, especially those from curated private collections featuring impressive diamonds and gold statement pieces,” said the director of Bonhams’ jewelry department, Emily Waterfall, in a statement. “The lots offered highlight craftsmanship from leading names in jewelry that will entice jewelry aficionados and collectors everywhere.” Among these names are legacy jewelers such as Cartier, Tiffany & Co. (including a few Schlumberger designs), David Webb, Mario Buccellati, Piaget, and more.

Below is a look at eight pieces in the auction, several of which are from the art deco period (including a 1925 carved agate desk clock by Cartier) and have the same appeal today as they did then.
