The Fantastic World of Tungsten Carbide

By Janine Carroll


Celtic Rings have a deeper meaning than your standard rings and wedding bands. Celtic rings symbolize love, happiness and life. The ever popular Claddagh ring has symbolized for ages the status of a person and whether or not they are single or if there heart belongs to another.

Tungsten is the perfect combination of unbelievable strength with style and comfort. Tungsten carbide is roughly 10 times harder than 18k gold, 5 times harder than tool steel, and 4 times harder than titanium. Tungsten measures between 8 and 9 on the Mohs hardness scale. (Diamonds are a 10 - the highest.)

Composition is usually 84% of tungsten and 16% of carbon and nickel. There is no cobalt in the composition of our rings. Cobalt will develop a negative reaction to your skin and will in a short time period will develop oxidation spots that cannot be removed or polished from your ring. This is due to the Cobalt reacting to the human body.

* Nickel-binder tungsten carbide is hypoallergenic, chemically inert and therefore will not oxidize, cause rashes, or irritate the skin. Good jewelers do not use cobalt as it can have an adverse reaction with the wearer's skin, sometimes causing a rash. Cobalt bonds with oils in the skin and leeches out of the ring resulting in oxidation. The oxidation appears similar to tarnished sliver, but cannot be removed by polishing or grinding. Nickel, on the other hand, does not bond with oil and therefore does not oxidize.

Recently, many of the Tungsten Carbide Ring companies have begun to manufacture Tungsten Rings and Wedding bands with Celtic designs circling the ring. Carved Tungsten rings have just recently emerged in the Tungsten market. Carved Tungsten Rings have deep inner grooves manufactured in the Tungsten ensuring the design and meaning will last a lifetime. Choosing Tungsten for your Celtic ring of choice would be a decision that would truly symbolize forever.
