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.
“She was a woman of grace, character, compassion, brains, and beauty,” said former Palm Springs Mayor Robert Moon. “She wanted everyone around her to be better off.”
Proceeds from her collection will benefit Cravens’ favorite charities.
