A tropical ocean of rare and sparkling blue diamond protected by shoulders of glittering diamonds and set in an 18ct white gold band paved with more diamonds is the Chopard Blue Diamond Ring valued at nearly £10 million and one of the most expensive pieces of diamond jewellery in existence.

Blue diamonds take their colour from boron deposits which gives the diamond its distinctive ultramarine, aquamarine and sapphire glow. Rare, expensive and decidedly exclusive a blue diamond ring isn’t for everyone.

The diamond in the Chopard Blue Diamond Ring weighs 9ct alone and its flawless appearance challenges all rings that stand beside it. In real terms, this beautiful ring would cost over £1 million per carat.
