Behold, the first all-diamond, diamond ring. From the Shawish website:
Shawish secured the copyright for the all-diamond ring one year ago in Geneva. It took one year to get the copyright and Shawish had to undergo multiple tests with the design to get the precision of the circle right using special laser equipment to cut directly into the diamond. The most important aspect is preserving the integrity of the diamond and of course the most difficult phase is precision cutting an entire stone into a ring. Shawish is now in search of the perfect hand to create the £43million, 150-carat masterpiece.
Apparently that hand has been found, because according to Styleite, the first one is now for sale for $70 million.
