RAPAPORT... A fancy intense blue diamond will lead Bonhams’ London auction next month, with the company estimating it could fetch close to $2 million. 

The pear-shaped, 4.03-carat stone has been in a UK private collection for more than 30 years, Bonhams said last week. The London-based auction house expects the jewel to sell for between $1.5 million (GBP 1.2 million) and $1.9 million, it said.

“Blue diamonds are extremely rare and highly coveted,” said Jean Ghika, Bonhams’ head of jewelry for the UK and Europe. “We are looking forward to showcasing this stone, along with other selected lots, in London, New York, Hong Kong and Geneva, where we anticipate considerable interest.”

Other items on offer at the Fine Jewelry auction on September 20 include a brooch featuring a square, step-cut, 4.83-carat, fancy grey-blue diamond as a center stone. The piece also contains two fancy dark brown-greenish yellow diamonds, weighing 2.51 carats and 2.38 carats, as well as a 1.90-carat fancy pink diamond. The entire brooch, dating from the middle of the last century, has a pre-sale estimate of $837,000 to $1.1 million.
