A 102-carat 'perfect' diamond could become the most expensive ever sold to online bidder at ...

Sotheby's is set to auction off a 102-carat diamond that could become the most expensive jewel ever sold to an online bidder Only seven flawless white diamonds of more than 100 carats have ever been sold at auction While Sotheby's doesn't have an official estimate, comparable diamonds have sold for between $11 million and $30 million in the past, Bruning said.

If it's purchased by an online bidder, it would likely top the record for the most expensive piece of jewelry ever sold online - a pair of fancy blue and pink diamond earrings that sold for $6 million online in 2016 The stone belongs to an elite subgroup of diamonds known as "Type IIa," which are the most chemically pure type of diamond with the highest level of transparency While demand for everyday jewelry sold in stores has plunged - since people aren't visiting malls and shops as often, or wearing jewelry as often - prices for so-called investible diamonds have remained strong.

Sales of jewelry and diamonds online have also increased, as people buy more from home. . Source
