Platinum Ring and Tungsten Carbide Ring

Many rings and wedding bands are constructed out of platinum, which is also a precious metal. While platinum is harder than silver and gold, tungsten carbide is much harder than platinum. Platinum only offers a maximum hardness rating of around "4" on the Moh's hardness scale. Platinum is also very ductile; a ring made out of platinum will bend under high pressures. Platinum rings are some of the most expensive rings on the market, they are usually much more expensive than tungsten carbide rings.
