Tarnish is when the silver turns black. This is very common and is nature’s way of “Oxidizing”. Like Steel rusts, the color is Brown, and Sterling Silver will Oxidize or Tarnish, turning yellow and darkening to black.
Unfortunately, some of my customers will Tarnish the silver faster than others for reasons I don’t understand. But I have started using an Alloy that doesn’t Tarnish as fast, but I can not guarantee that it will not Tarnish.
Please use a simple silver/gold polishing cloth if my work tarnishes. For a $20 fee plus $7 shipping, you can send it back, and I will make it look new again. Please see the “Repair and Sending Items Back question” Sending items back for Repair and Exchange.
