According to IDEX Online, a 31.62-carat Fancy blue diamond pendant necklace is expected to earn between $10 million and $15 million at Christie’s Magnificent Jewels auction next month.
The GIA has assessed the pear-modified brilliant stone as natural colour, VVS1 clarity, and probably Internally Flawless. “Set amid round diamonds and pink diamonds in platinum and rose gold,” the stone says.
Another pendant necklace will be featured in Christie’s Magnificent Jewels auction on December 6. This one has an 86.64-carat pear brilliant-cut diamond as well as 78 pear brilliant-cut diamonds ranging from 2.50 to 0.50 carats totaling 87.73 carats in platinum and white gold. It is expected to sell for between $5 million and $7 million.

Blue diamonds are a type of diamond that has all of the inherent properties of the mineral except for the addition of blue colour in the stone. They are blue due to trace amounts of boron in the crystalline lattice structure.
On average, a 0.5 carat light blue diamond costs $26,280. Deep blue and vivid blue diamonds are much more expensive, costing around $75,000 for a 0.25 carat diamond. Blue diamond prices rise as colour intensity and carat weight increase, reaching $100,000, $200,000, and beyond.
