BLUE DIAMONDS
Where blue diamonds come from
Rough blue diamonds mainly come from Australia, South Africa and sometimes from India.
Why they are blue
Blue diamonds get their color because of boron. They are extremely rare and generally are a little grey. Very few stones are mined each year.
In the world there is not a diamond that looks like another one.

Famous Diamonds
The biggest blue diamond in the world is the Idol’s Eye, 70,21 ct. Around 1607, the stone is said to have been belonged to a persian prince named Rehab. In 1947, the Idol’s Eye is sold to Mrs May Bonfils Stanton, Frederick G. Bonfils’s daughter, the publisher and co-founder of the Denver Post newspaper, who liked wearing the Idol’s Eye to breakfast every morning. According to a romantic tale, the Idol’s Eye has been torn from a statue’s eye of a Hindu deity venerated in India.
