Stainless steel jewelry now comes in a variety of colors. A coating process far superior to gold or silver plating known as physical vapor deposition is used.
Physical vapor deposition (PVD) is a way of adding a thin layer of material to a surface.
If you’ve grown frustrated with the limited time you have to enjoy gold-plated jewelry, you need to look for pieces that won’t lose their golden shine, exposing the underlying base metal. I love to work with those base metals but covering them with a thin layer of 14k gold doesn’t work. At least not for long.
