Sterling Canyon wants you to walk into your favorite department store and proceed to the jewelry counter. Check out the black diamond collection. Beautiful aren’t they? And expensive too. Look closely and you’ll be surprised. There are several ways to make a white or clear diamond black. In the old days, an inferior white diamond would be placed in a setting like in a ring. Behind the diamond would be placed a small piece of foil. This would cause the light entering the diamond to bounce around and not exit the crystal properly, giving the black appearance. You’ll find this trick in antique jewelry and possibly in cheap chinese-made jewelry.
The more modern method is to radiate the stone. The crystal is bombarded with neutrons, turning the stone a dark green which appears black. Look at the stone with a jewelers glass. If the stone is green on the edges, it’s been irradiated. A natural black diamond will be black through and through. The nice thing about irradiation is that the color is permanant. The bad thing about irradiated stones is that they are a poor quality diamond that is over-priced. Sterling Canyon doesn’t want to see you make a fatal high priced mistake. If you want a black diamond look, go with artificial. Or pay for the real thing. Your bank account will be happy either way.
