time:2023-09-19 source:sznbone Views:

The main varieties of gold jewelry include rings, earrings, necklaces, bracelets, brooches, etc. When choosing gold jewelry, the first step is to identify its authenticity by:

Weigh the weight. Compared to metal jewelry of the same volume, gold has a higher weight.

The second is to listen to the sound. Throwing the gold jewelry onto the ground will make a "popping" sound, while those with low content will have clear and crisp pronunciation.

The third is to look at the color. The luster of gold jewelry lasts for a long time, with high gold content jewelry appearing in red and poor in yellow.

The fourth is to test the hardness. The higher the gold content of the jewelry, the softer it becomes. Use a hard needle to scratch it once, and obvious marks will appear; The imprint with low gold content is blurry.

Five is hand bending. True gold is soft and can be bent by hand, making it easy to bend but not easy to break, while accessories with color differences are easy to break and not easy to bend. Six is to burn with fire. Burn jewelry with high fire, real gold is resistant to burning and does not change color, while fake gold loses its luster and even turns black purple after burning. The seventh is acid test. Gold is insoluble in hydrochloric acid, sulfuric acid, and nitric acid, while other metals change when they encounter three acids.
