As blue diamonds are never abundant in the diamond industry, expert’s expect that the blue diamond price range will be from $1.5 million to $1.9 million.

Interested parties for the fancy intense 4.03-carat blue diamond set in a two stone pendant immediately registered for this sale on September 20. The Blue diamond comes with a GIA report and additional letter stating that the diamond has been classified as Type IIb.

The head of Bonhams jewelry UK and Europe shared that “blue diamonds are extremely rare and highly coveted” continuing by saying “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”.
