The largest Kashmir sapphire to hit the block, according to Sotheby’s, and several stones weighing more than 100 carats are on offer.

The sale will also include an 80.45-carat step-cut Colombian emerald and diamonds set in a brooch/pendant estimated to go for between $2.5 million and $3.5 million.
Meanwhile, at the Sotheby’s New York Magnificent Jewels sale on April 15, bidders will have the chance to own an 82.54-carat oval-shaped Madagascar sapphire and diamond necklace.
The lot is estimated to garner between $200,000 and $300,000 but will sell with no reserve, meaning there is no minimum price for it.
The jewelry auction will also offer a Cartier ring set with a 43.35-carat emerald-cut fancy vivid yellow diamond ($2.39 million-$3.1 million) and an unmounted 39.88-carat emerald-cut D color, flawless, Type IIa diamond ($3.9 million-$5.2 million).
