With the increasing price of material, the price of gold and diamond jewelry is increasing, too. However the style is still following the same pattern, which can hardly meet people’s need for presence of individuation and changeable fashion. With this marketable demand, modern silver jewelry comes to the fashion stage, which makes largely up to the silver market. The style of silver jewelry is abundant and the price is reasonable; and it can follow the step of fashion, which makes it suitable for any clothes. All in all, silver jewelries are everyone’s favorite. So how to identify the quality of silver jewelries becomes especially important in this condition.
Firstly, we decide on the color. The higher puritythe jewelries have, the whiter they are. The surface of jewelries seems evenly sparkling. But if they contain lead, the jewelries will present a dark grey; if they contain copper, the ornaments will look vulgar and not glossy.
Secondly we decide on weight. The intense of silver is a little bit larger than that of other metals. Normally, aluminum is light and silver is heavy and copper is between them. So we can totally feel the weight to guess whether it is silver or not at the first place. If the silver jewelry has a large volume but a light weight, we can make the first impression that it is silver but other metals.
Thirdly, we decide on the hardness. The hardness of silver is lower than that if copper but higher than that of lead and tin. We can use a needle to scratch the unnoticeable place of the jewelries to test its quality: if there can not be left any trace, it is copper jewelry; if there can be easily left some trace, it is lead or tin jewelry; if there is a light trace, it is silver jewelry.
Fourthly, we decide on the sound. There is no flexibility and a loud bang when you throw a silver jewelries into the floor. The lower sound there is, the worse the jewelry is. On the other around, the better the jewelry is. If it is a copper one, the sound will be sharper and louder, and the rhythm will be short and quick. If it is a lead or tin one, there will be a stable and short bang without any flexibility.This paper from the http://www.jewelryshopvip.com
