How to judge whether the necklace is pure silver?

Whether jewelry is pure silver is mainly judged by luster, texture, elasticity and oxidation degree.

1, pure silver has a soft luster.

As shown in the picture, there is pure silver on the left and nickel-plated silver ornaments on the right. Pure silver jewelry is soft and moist under the light, while electroplating products will refract light and feel dazzling visually.

2. The texture of pure silver is smooth and delicate

As shown in the figure, the pure silver on the left feels more delicate and smooth; There are concave and convex notches on the surface of the nickel-plated silver ring on the right, which is rough to the touch.

3. Pure silver is more elastic.

Pure silver products have good toughness and are not easy to break when forced to bend; In order to reduce costs, some black-hearted manufacturers use hollow or internal silver powder, which is easily broken.

4. Pure silver is easy to be reduced after oxidation.

The pure silver ornaments that change color due to oxidation will slowly restore luster after wearing for about a week, as shown in the left picture. On the right is a nickel-plated silver-plated necklace, which cannot be recovered no matter how long it is worn after oxidation.
