Tiffany & Co. is currently selling its most expensive piece of jewelry ever.

"The World's Fair Necklace," unveiled in Dubai on Sunday, boasts a dazzling 180 carats of diamonds set in platinum.

The 578 total diamonds include 353 round brilliant cut stones and 224 custom-cut baguettes. The centerpiece is an 80-carat oval, flawless D-color (highest grade and virtually colorless) "Empire Diamond," getting its name from the Empire State Building in the retailer's city of origin, New York. The Empire Diamond was ethically sourced in Bostwana, cut and polished in Israel, then set in the jeweler's New York City workshop.

The centerpiece in the World's Fair Necklace can also be converted into a ring; a Tiffany jeweler will be on call to mount it onto platinum whenever the wearer chooses. 

Although the iconic jeweler has yet to reveal the price of the piece, industry experts estimate the cost is between $20 million and $30 million. 

Tiffany said the design for the World's Fair Necklace was inspired by a Tiffany necklace created for the 1939 World's Fair held in Queens' Flushing Meadow-Corona Park. That piece incorporated a 200-carat aquamarine stone and 429 diamonds.

The Empire Diamond might be Tiffany's largest and most expensive ever for sale, but it's not the retailer's biggest diamond of all time: That title goes to the famous 128.54-carat "Tiffany Diamond," which the company said is priceless and not for sale.
