Have you ever wondered how tungsten carbide stacks up against titanium and other materials commonly used to make men’s wedding bands? Which is better, tungsten or titanium? Below is the Mohs Scale of Mineral Hardness, a qualitative ordinal scale of mineral hardness or scratch resistance, based on the ability of one mineral sample to visibly scratch another mineral sample.
The Mohs Scale below includes common materials used in the jewelry business. To give you a better picture of the hardness of these materials, we included fingernail and tooth on the scale for comparison.
As you can see, diamonds get a perfect “10” for being the hardest and most scratch-resistant material on earth, which means nothing can scratch it except another diamond. Tungsten is the hardest and most scratch-resistant metal, but nonmetals such as diamonds, sapphires and other hard crystals can still scratch it. If you’re thinking titanium, bear in mind that it’s far less scratch-resistant than tungsten.
Often, materials on the lower part of the Mohs Scale can create tiny dislocations on materials higher up on the scale. But even though these microscopic dislocations are permanent and sometimes even disruptive to the harder material's physical structure, they aren’t regarded as scratches according to the Mohs Scale determination of hardness.

Pros: Most scratch-resistant metal and very affordably priced. Very easy to remove in case of medical emergency — no cutting or sawing. Hypoallergenic
