Osmium Tennis Bracelet

The term 'tennis bracelet' became popular after tennis star Chris Evert's diamond bracelet broke during a match at the 1978 U.S. Open, causing the game to be paused while she collected the diamonds. From this moment on, the bracelets with their flexible string setting and single strands of gemstones have become increasingly popular, not least because they were worn by no other than Princess Diana. 

The osmium tennis bracelet consists of 75 2mm osmium squares, embedded in white gold.
