Collectors all over the world are buzzing about the Pink Star, a 59.6 carat oval mixed-cut pink diamond that is the largest internally flawless fancy vivid pink diamond the Gemological Institute of America has ever graded. The sparkler is set to make a rare re-appearance on the auction block come April 4, when it will be awarded to highest bidder at a Sotheby’s sale in Hong Kong.
Aside from the rarity, the stone's backstory makes it all the more interesting. The diamond was sold by the auction house for a record-setting $83.2 million back in 2014, but the winning bidder failed to pay for the pretty piece after investors backed out. For undisclosed reasons, the second-highest bidder wasn't approached to purchase it and the gem instead remained in the Sotheby's inventory.
The Pink Star is estimated to be worth well over $60 million, but experts suggest that the stone could fetch upwards of $100 million when it sells—making it the most expensive diamond in history.
A girl can dream, right?
