More than two years after Shirley Temple's death, one of the screen icon's most prized possessions is hitting the auction block.

Among the 300 items set to be sold in Sotheby's upcoming "Magnificent Jewels” sale is the late star's stunning 9.54-carat blue diamond ring. According to the auction house, Shirley's father bought the cushion-cut stone for $7,210 in 1940 for his famous daughter as a 12th birthday present. It is now expected to fetch between $25 and $35 million at auction.
