Because tungsten is approximately 10 times harder than gold, it is a top choice when searching for a more scratch-resistant material for wedding bands. The metal has even been referred to as having a "permanent shine" by some. How does the look of an older gold or silver ring compare with a newer one? Dents, scratches, and wear marks often make it appear older than it actually is. It happens to metals such as Sterling Silver, White Gold, Yellow Gold, and Rose Gold.
