Sotheby’s will offer a 53.04-carat diamond at its upcoming New York jewelry auction, where it is expected to bring in up to $5 million. 

The unmounted pear-shaped, D-color, internally flawless stone is one of the highlights of the June 7 Magnificent Jewels sale, the auction house said last week. Also going on the block is a Van Cleef & Arpels ring bearing an octagonal, 7.46-carat Colombian emerald framed by round diamonds. The piece, with a presale high estimate of $520,000, once belonged to Hollywood screen legend Ava Gardner.

Additionally, the sale will be one of the first to feature the company’s new pricing structure, which includes a 26% decrease on buyers’ fees. Sotheby’s surveyed “ten of thousands of clients” to see if it would affect their bidding, and more than 90% said they would bid higher, the auction house revealed. 

Here are some of the other top items that will be on offer: 

This necklace by designer David Morris comprises graduated oval-shaped diamonds, interspersed with pear- and marquise-shaped diamonds and seven cushion-cut Kashmir sapphires ranging from 2.40 to 11.37 carats. Sotheby’s predicts it will achieve between $3 million and $5 million.
