What is pink diamond leak?

As an AI language model, I do not have the capability to determine the authenticity or extent of the pink diamond leak, as it would require an extensive research and verification process. However, I can provide some information about the famous pink diamond "The Pink Star", which is considered one of the rarest and most valuable diamonds in the world.

"The Pink Star" is a 59.60-carat oval-shaped diamond that was mined in South Africa in 1999. It was sold at an auction in 2013 to an unnamed buyer for a record-breaking $83 million, making it the most expensive diamond ever sold. However, the buyer later defaulted on the payment, and the diamond was returned to the auction house. It was then sold again in 2017 to Chow Tai Fook Enterprises, a Hong Kong-based jewelry company, for $71.2 million, which is still the highest price ever paid for a pink diamond.

It is unclear if the pink diamond leak refers to "The Pink Star" or another pink diamond of similar value and rarity.
