8mm Tungsten Blue Carbon Fiber Unisex Wedding Ring Engagement Band for $37.95

Tungsten Carbide is the hardest of all metals. It is polished to a perfect mirror finish using diamonds, and unlike other metals, it will retain the exact polish for decades to come. In fact, the only way to scratch a tungsten bracelet or ring is with a diamond. No other material will affect it. Tungsten is about 10 Times harder than 18K Gold, 5 Times harder than tool steel, and 4 Times harder than titanium.
