How is tungsten carbide jewelry blackened?

April 12, 2010

Hello, I work in the jewelry industry and find your site fascinating. There are so many cross-over applications! I just know there is someone who can fill me in on the current practice of how the patterns are achieved on tungsten carbide rings. I understand a little about laser tech and wanted to know how the black color is applied. Any info is very helpful, thank you!
