NEW YORK (AP) – A rare, 100-carat emerald-cut white diamond is going on the auction block in New York.

Sotheby’s says the internally flawless D color gem is considered “perfect.”

It’s being offered on April 21 with a pre-sale estimate of $19 million to $25 million.

Sotheby’s says it’s the only classic emerald-cut white diamond of the highest quality and over 100 carats to come to auction.

The rough diamond was mined in southern Africa and weighed over 200 carats.

Only five “perfect” diamonds over 100 carats have sold at auction in the last 25 years. A 118-carat oval-cut stone fetched $30.6 million at Sotheby’s in 2013, a record for a white diamond.

A record for any diamond is $46 million for a 24.78-carat pink diamond. It was set at Sotheby’s in 2010
