The Blue Heart Diamond

The Blue Heart Diamond was found at the Premier Mine, South Africa in 1908. The 30.62 carat heart-shaped, brilliant cut blue diamond was faceted in 1910 from a 100.5 carat rough.

Mrs. Marjorie Merriweather Post was the last private owner of the diamond. She purchased the stone for $300,000 from Harry Winston in 1953. She gifted the Blue Heart Diamond to the National Gem Collection in 1964.
In 1997, the GIA graded the Blue Heart as a natural fancy deep blue diamond with a clarity grade of VS-2.

The record-setting auction prices of blue diamonds over the last few years has attracted considerable attention. While blue diamonds are rare enough to be extremely valuable, they are abundant enough to have and sustain a market. Its thought today the Blue Heart Diamond could be worth $ 60m or more.

The Oppenheimer Blue. 14.62 carats, fancy vivid blue. $60m or $ 4.1m per carat
