The biggest white diamond ever mined just sold for nearly 22-million dollars.
"The Rock," as it's known, sold at Christie's annual Magnificent Jewels auction in Switzerland on Wednesday.
Christie's refused to name the buyer or even say where they live.
While the 21-point-nine million dollar sale price is breathtaking, it's a lot less than the auction house expected it to bring.
In mid-April, Christie's was hoping "The Rock" would fetch well over 30-million dollars.
