The tungsten rings is now the ideal wedding rings, especially the mens tungsten wedding bands are very popular. When the tungsten rings became popular, some jewelers began selling "pure" tungsten rings. However, the use of tungsten alone can cause the jewelry to be easily scratched and destroy the beauty of the rings.
Tungsten rings is the alloy metal, in most cases nickel-binder carbide which gives tungsten carbide its "permanently polished" appearance. There are tungsten rings created using cobalt as a binder because it's cheaper. However the problem with using cobalt is that it bonds with oils in the skin, over time, the cobalt leeches out of the ring and can irritate the skin because of oxidation. Unfortunately once this happens no amount of grinding or polishing will remove the oxidation which is very similar in appearance to tarnished silver.
The main reason that quality jewelers prefer nickel-binder carbide is because it's hypoallergenic,it won't irritate the skin. It's also chemically inert, it doesn't bond with body oils so the problem of oxidation is eliminated. Using nickel-carbide allows jewelry designers to create wedding rings that are visually appealing and at the same time super-durable.
It's important to ask the jeweler which alloy was used in the Tungsten Carbide ring you want to purchase. Not every jeweler knows this information and if they cannot assure you that it's a nickel-carbide alloy, you can almost be certain that it's cobalt. Pure tungsten not only scratch very easily, they also shatter when dropped onto a hard surface. The nickel-carbide alloy supports maximum hardness and rigidity of tungsten and its tensile strength.
The growing popularity of tungsten rings proves that you can find more affordable and beautiful rings. Mens silver wedding bands or black wedding rings are popular with men.
