Tungsten carbide in wedding rings is fast becoming popular due to its lustrous colour that polishes to an attractive mirror finish, and because the metal is incredibly hard - the hardest to be used in jewellery. Of course, no metal is completely impervious to harm - with hardness comes brittleness, and you must be careful to ensure your tungsten ring fits well enough not to risk it being dropped, or flying off the finger. Tungsten carbide rings are a very popular choice for those with hard wearing jobs because they resist scratches far more than other materials. Contrary to some people's beliefs, tungsten carbide can be removed from the finger in the case of a medical emergency. Whilst tungsten carbide can't be sawn off in the same way as gold or silver, it can be removed by cracking the metal in a vice or pliers. Whilst tungsten is too hard to be engraved in the conventional way, we can use laser engraving technology to engrave our tungsten carbide rings.
Tungsten carbide is so resilient that surface dirt can be cleaned with a soft cloth in a mild soapy solution. This cleaning process should not cause stains or scratching. Tungsten carbide rings cannot be re-polished like more traditional precious metals due to its hardness, however should retain its beautiful polished finish for years to come.
Tungsten Carbide (often just known as tungsten) is a chemical compound of tungsten and carbon. It is roughly 10 times harder than 18ct gold.
Tungsten carbide requires a small amount of cobalt in the alloy in order to be shaped. Many people are wary of cobalt as its use in jewellery is regulated by the EU. Our tungsten carbide wedding bands are officially cobalt free because they contain such minimal amounts to be within the EU guidelines.
Tungsten carbide is incredibly hard, so it's used across different industries where a metal is needed that withstand wear and tear. It's used in surgical instruments, skis, farriery and ammunition.
Tungsten (translating in Swedish and Danish to "heavy stone"), also known as Wolfram in Sweden, was first suggested to exist by Peter Woulfe in 1779. It took a further 150 years before it really started being used in the industry. The beginning of tungsten carbide production can be traced to the early 1920's, being used as the filament inside the bulb due to its toughness and resilience which exceeds any other metal.
Like gold, silver and platinum, Tungsten is an element #74. It is naturally occurring and is one of the main elements responsible for the development of human civilization. In 1922 the Germans developed tungsten carbide as the material used in making better cutting tool bits for precision milling and cutting of steel. In World War II, tungsten played an enormous role as the extreme strength of its alloys, made the metal into a very important raw material for the weaponry industry. Tungsten carbide has only recently started to be used within jewellery due to its extreme hardness and hypo-allergenic qualities.
