What are Blue Diamonds?
As blue is one of the rarest occurring colours in nature, it is also one of the most desired natural coloured diamond hues. Blue diamonds are among the least common colours of fancy coloured diamonds, which themselves make for only 0.01% of all extracted diamonds. Blue brilliants are characterized by their high clarity, which, combined with their rarity, puts them in the top most expensive coloured diamonds.

It is not surprising, given that it is known for its calming and nurturing effects. For that reason, it might be the perfect choice, presenting it as an engagement ring to a loved one.

Famous Natural Blue Diamonds
This diamond weighs 31.06 Ct, while its colour has been graded as Fancy Deep Blue of IF clarity. It comes from the Kollur Mine in India, where it was mined in the 17th century. Then in 2008, it was bought by Laurence Graff who renamed it from Wittelsbach Diamond to Wittelsbach-Graff Diamond. After this transaction, it was repolished, which is now considered by many critics a bad decision due to the loss of its character and history.
