A 9.54ct fancy blue diamond ring worn by Shirley Temple failed to sell at Sotheby’s Magnificent Jewels auction held in New York City, April 19.
Bidding for the ring, known as the Shirley Temple Blue, started at $19 million (£13m) and reportedly reached $22 million (£15m), which was below the ring’s reserve price.
A Sotheby’s statement said: “The Shirley Temple Blue Diamond is an exceptional stone in quality, rarity, and provenance… Unfortunately, tonight wasn’t its night in the sales room, but we remain fully confident that it will find a buyer.”
The Shirley Temple Blue is considered potentially internally flawless.
The ring was purchased by Temple’s father in 1970 for $7,210 (£5,000). Temple owned the stone until her death in 2014.
