Los Angeles—Diamond lovers and collectors of pieces from major jewelry houses won’t want to miss Bonhams’ upcoming auction.
 
The California Jewels sale is slated for Feb. 22 in Los Angeles. 
 
The lot with the highest pre-sale estimate is an exceptional diamond ring (below).

The ring is one of 20 jewels from the estate of philanthropist Peggy Koerner Cravens, who lived from 1931 to 2022.

She and her late husband, Life Magazine photojournalist Donald Cravens, donated the Donald and Peggy Cravens Student Services Center to College of the Desert.

Proceeds from her collection will benefit Cravens’ favorite charities.

All the stones range from D-color to F-color and are between VS and SI clarity. They total 10.35 carats. The dress clip is expected to sell for $75,000 to $100,000. 
 
Diamonds are a major focus of the sale.

Another notable diamond ring is the above platinum and three-stone diamond ring. It features three oval-cut diamonds weighing a total 6.05 carats. The stones are E-F color and range between VVS2 and VS2 clarity. 
 
The ring is expected to sell for $35,000 to $55,000. 
 
 
Diamond bracelet lovers will delight in the above platinum and diamond bracelet that features a total 265 diamonds. The stones are a combination of marquise-shaped, baguette and round diamonds, all G-, H-, or I-color and VVS-VS clarity.
 
The bracelet is estimated to sell for between $22,000 and $28,000. 
 
Speaking of bracelets, there are several bold cuffs from major jewelry houses on offer. 
 
The below Verdura 18-karat gold and gem-set wood bracelet features the brand’s signature Maltese cross. It’s encrusted with ruby and emerald cabochons, round cultured pearls and round diamonds.
 
 
It’s expected to sell for between $18,000 and $22,000. 
 
The below David Webb cuff ($8,000-$12,000) is crafted in 18-karat gold with a 16.10-carat aquamarine set in platinum and surrounded by round diamonds.
 
 
The below Angela Cummings for Tiffany & Co. hinged bracelet ($8,000-$12,000) circa 1981 features coral and aventurine inlay that forms a rose.
