It is said that stainless steel jewelry has high corrosion resistance, high temperature resistance and hardness, and the surface will not change due to the environment. It can maintain luster and smoothness for long-term wear, and is very similar to platinum. So how should we distinguish stainless steel jewelry from platinum jewelry
Let's first understand their characteristics so that they can be more easily distinguished. Platinum jewelry, also known as platinum jewelry, has high density, high ductility and low reactivity. It is a kind of gray white precious metal with bright luster and is not easy to fade. Stainless steel jewelry is resistant to weak corrosive media such as air, steam and water, and has rust resistance. Because it is easy to plastic, it can easily make the appearance that other jewelry can't make, so it is deeply sought after by the market
So how to distinguish between the two? Platinum can be determined by hydrochloric acid or acidic solution and will not dissolve in ordinary acid; Stainless steel can be put into the solution to see if there are bubbles. There is also a more direct way to see whether there is a platinum mark on the back of jewelry processing. According to national regulations, the back of each platinum jewelry must be engraved with a platinum exclusive mark: Pt or platinum (Platinum)
