The World's First All Diamond Ring

In March 2011, word broke out that Shawish Jewelers of Geneva had created the world's first diamond ring, a ring with no setting or metal, the story of this unusual piece of jewelry was featured on news and blogs across the world. Images of the ring has been released since and ironically it's of a similar shape to the plastic gemstone rings found in gumball machines. Well that only my opinion but check it out for yourself. 

The ring was created entirely from one single diamond weighing 150 carats and is expected to fetch around $70 million dollars. However, the making of the world's first diamond ring wasn't easy, it took one year to get the copyright and then multiple tests had to be taken to get the precision of the circle right. Diamonds are made from carbon and molecules that can change, so the colour can alter when trying to cut it.
