"A one-off palladium Diamond Tsunami Ring designed by Paul Draper will be sold at auction, with profits going towards victims of Japan's Tohoku Earthquake.

Draper has gone to great lengths to ensure this ring is unisex, utilising black, brown and orange diamonds to accentuate the piece's aesthetics, alongside an engraved platinum collet set with six blue, white and brown diamonds.

Different aspects of the ring's design are intended to reflect consequences of the disaster, making it an entirely unique collectors item.

The collet houses a marquise shaped diamond, which represents one of the sea vessels that was washed inland under the force of the tsunami.

"I made the centre collet and master patterns by hand in two separate halves in order to overcome an impossible setting procedure," explained Draper. "To achieve the desired end product I then drew upon the specialist skills of six different craftsmen from differing sections of the jewellery trade."
