The silver diamond auction is real. Although the silver-inlaid diamond may not be as expensive as other gems, it is still a real gem and can be used to make jewelry. Silver-inlaid diamonds are generally a mixture of more expensive gems and cheaper gems, including diamonds, pearls, rubies, sapphires, emeralds, tourmalines and so on. And these gems are real, just at different prices. In addition, silver-set diamonds are also made of real silver, so they can also be called real gems.
