An Art Deco Cartier diamond and rock crystal brooch sold for 10 times its high estimate, becoming one of the top five lots ever sold at Chiswick Auctions.

The piece was formerly owned by New York socialite Augusta McCagg, a relative of the Vanderbilt family, famous for its shipping and railroad empires. It brought in GBP 150,000 ($212,350) at the May 28 sale after highly competitive bidding, the London-based auction house said last week.

“This Cartier brooch is a wonderful example of the early influence Indian art had on the jewelry being created by Cartier,” said Sarah Duncan, head of jewelry at Chiswick Auctions. “Extensive research into the family history and connections, compounded by the fact that this piece has never before been on the open market, made it very desirable to our international bidders.”
