Bonhams sold several items for well above their high estimates at its recent California Jewels sale, with the top lot going for four times its upper price.
The platinum, sapphire and diamond ring by important Beverly Hills jeweler Ruser achieved $127,500 at the September 19 sale, the auction house said last week. The ring bears an octagonal step-cut, 21.15-carat Sri Lankan sapphire framed by 3 carats of round diamonds. William Ruser and his wife founded Ruser in 1947. Known for its innovative use of materials and a following of Hollywood stars, the company stayed in business until 1969, when the owners sold their Rodeo Drive location to Van Cleef & Arpels.
In total, the sale brought in more than $1.5 million, with 72% of the 308 lots on offer sold.
Here are the rest of the top 10 lots:
