Angelina Jolie has some. So does Cate Blanchett. As do Evan Rachel Wood, Jennifer Lawrence, Lauren Conrad and Sarah Jessica Parker. What do these Hollywood stars and starlets have in common? They wear earrings set with black diamonds. This probably most exciting form of fancy diamonds is very much in vogue on the other side of the Atlantic. So trendy, in fact, that fashion icon Carmen Electra, for example, received an engagement ring set with a black diamond from rocker Rob Patterson. The aforementioned Jolie gave her husband Brad Pitt a pair of unusual cufflinks set with black diamonds. But black diamonds are not only in demand in the New World: they are also very popular with the public here in Germany, which could also benefit the jewellery industry.
