Hardness of Tungsten Carbide Ring and Titanium Ring

Both tungsten carbide and titanium are harder than gold, silver and platinum. This is because the alloys used in both metals offer strength to these metals that under most circumstances are virtually indestructible. If jewelry made from tungsten carbide and titanium were placed under extremely abrasive conditions, such as the cut of a diamond, a tungsten carbide ring would prove stronger than the titanium.
