Shirley Temple’s Blue Diamond Ring is hitting the auction block

It would appear that big blue diamonds are having a serious moment right now.

In November, a Chinese billionaire purchased a blue diamond for his 7-year old daughter for $48.4 million. Yesterday it was announced that The De Beers Millennium Jewel 4 is hitting the auction block in Hong Kong next month, where it is expected to fetch $36 million.

And today comes the news that Shirley Temple’s Blue Diamond Ring will be auctioned on April 19th in New York City at Sotheby’s Magnificent Jewels auction.

The cushion-cut Fancy Blue Diamond is surrounded by diamonds and set in platinum. The ring weighs a very impressive 9.54 carats and is estimated to sell between $25 to $35 million.

“This was a treasured piece of jewelry that she wore and enjoyed her entire life,” said Frank Everett – sales director for Sotheby’s jewelry department in New York – to NBC.

Everett also told NBC that the ring had been sold by her estate to a private buyer and that buyer was now putting it up for auction.

It was originally purchased by the child star’s father George Temple in 1940. According to People it was a gift to celebrate both her 12th birthday and the premiere of her film The Blue Bird, Temple reportedly paid $7,210 for the ring which today adds up to around $121,810. Bargain.
