The most expensive wedding ring in history

Walmart and Jewelry World are the latest major retailers to announce they will start selling rings made from copper and gold.

The news comes after Apple and Samsung announced their own partnerships to promote jewelry.

Apple announced its $20 million partnership with the U.S. goldsmith and jeweller Robert Green, who has been producing rings made with the precious metal for more than a decade.

Samsung announced its new partnership with an American goldsmith named Andrew Gorman. 

“We are delighted to partner with a company with such a deep history in making gold and silver jewelry and are excited to work with Andrew Golan on new designs for Apple Watch bands,” said Steve Jobs in a statement. 

Apple and Samsung have been partners in the jewelry space for years, but they have never partnered with the two top manufacturers of watches and wristwatches.

Apple and Sony both have partnerships with Japanese goldsmith Hiroshi Matsuyama, but only to produce jewelry.

Samsung and LG have made jewelry for years with goldsmiths in China.
