Features of Tungsten Jewelry Tungsten steel and tungsten gold are relatively hard metals in the world; their hardness is second only to diamond.It won't scratch, has a relatively high weight, and produces jewelry with a stronger texture.Tungsten is also a relatively rare material.Nowadays, tungsten gold is gradually being used as a jewelry material and is widely popular in the market. Why choose tungsten? Tungsten jewelry has the characteristics of being durable, resistant to fading and deformation, with a diamond-like luster at a much lower price than diamonds.Tungsten jewelry is a popular accessory in Europe and America nowadays, and young people really love it. Traditional gold and silver jewelry struggle to attract fashion-forward youth who seek individuality.Tungsten jewelry has also become a choice for gifts due to its special properties. How to identify tungsten gold? 1. Determine by weight: The density of tungsten gold is higher than that of titanium steel and other jewelry, so it feels substantial when worn, with a heavy metal feel. If it feels light when worn, you can be sure that the material is not genuine tungsten gold 2. Determine from hardness: The hardness of tungsten is 8-9M on the Mohs scale, close to natural diamond's 10M, equivalent to 10 times that of 18K gold, 4 times that of titanium, and 5 times that of stainless steel, ensuring no wear and tear. You can use a blade or a file to scratch the surface; tungsten gold material won't show scratches 3. Determine from time: Tungsten jewelry, due to its special material, has the characteristics of not discoloring and being highly resistant to wear and corrosion. No matter how long it is worn, it will maintain its luster. If after wearing for a while, the surface oxidizes and rusts, develops marble patterns after production, or fades and turns black, it can be concluded that the purity of the tungsten is not high or it may be mixed with other substances 4. Determine from Appearance: The first two points are to identify whether it is made of tungsten gold material; this point is about how to distinguish whether it is good tungsten gold jewelry.Tungsten Jewelry and Clothing Same material and style, but the price ranges from tens to thousands of yuan. The key difference lies in workmanship and attention to detail. A good tungsten jewelry no matter which angle you look at, the color is uniform and cool silver degrees.
