Most black tungsten rings are made with a plate over the natural gray tungsten. This is why you'll see a wide range of prices for tungsten rings - all the way from $10 dollars to over $500 for designer bands with diamonds. There are different types of jewelry grade tungsten carbide, and rings made with quality tungsten carbide (which contain a low amount of nickel and a high percentage of tungsten and carbon) are priced higher than rings made with lower quality tungsten carbide grades.

Not only does the cobalt cause allergic reactions, but the cobalt reacts with the oils in the skin and can create a permanent stain on the rings.

While nickel in gold alloys can cause allergies in some people, the amount of nickel in tungsten carbide is extremely low plus bonded so tightly to the other atoms in the ring that allergy risks are low. Quality tungsten wedding bands are made with jewelry grade tungsten carbide compounded with a nickel binder. The Best Tungsten Carbide for Tungsten Wedding Bands Tungsten wedding bands are also somewhat heavy - just a touch heavier than 14k gold.
It is a common myth that tungsten carbide rings cannot be removed during an emergency - but they can be removed in the event of an emergency using regular jewelry removal tools. Tungsten carbide wedding bands have moderate heat and electrical conductivity properties - so if this is a concern for you, it might be best to go with a wooden wedding band or a stainless steel wedding ring (or remove the band when working in a capacity where electricity and heat pose a safety issue). The rings too are extremely resistant to scratching, and have a light gray color which can be darkened with brush finishing processes. Tungsten carbide rings retain many of the characteristics of pure tungsten metal - including a high melting point and high tensile strength. The result is a very fine powder which is then mixed with a binder - like nickel or cobalt - to create a compound which can be crafted into different shapes - like razor blades and wedding rings. Tungsten carbide is created by combining an equal number of tungsten and carbon atoms. Pure tungsten is too difficult to work with, so tungsten that is used for industrial applications - and in jewelry - is compounded into its carbide form. It is extremely durable and somewhat rare.īut tungsten wedding bands are not made out of pure tungsten - instead they are made out of tungsten carbide. Out of all the metals, tungsten has the highest melting point and the highest tensile strength. What is tungsten exactly? Tungsten is a chemical element, also known as wolfram, and it has some pretty amazing properties. Characteristics of Tungsten Carbide Wedding Rings
