It’s rare and it’s pink.I’m talking about a 5-carat pink diamond, will be available in Hong Kong by Christie’s.Some says this pink diamond would be one of the most expensive diamond on sale. The pink diamond also, called “cushion-cut” ring by famed jewellers Graff Diamonds, is expected valued between $5-$7 million.Perhaps this would be a world auction record for a pink diamond since a 19.66-carat stone that sold in Geneva for $7.4 million in 1994.
