Matters needing attention in buying gold jewelry:

1. Weigh. If the object is gold, it feels heavy, which is what people call "gold falling hands", and vice versa.

2. Look at the color. Pure gold will shine brightly under strong light, which other metals, including copper, do not have.

3. Review phonology. Gold jewelry is thrown on the floor and makes a plop sound. The fake sound is sharp and bright, and it jumps higher than gold.

4. Fold hard and soft. Gold has the characteristics of good ductility and low hardness. Pure gold is soft when folded, and copper bars are laborious when folded.

5. Use acid. Gold is insoluble in acid, but it will react with acid solution because it is mixed with other active metals such as copper.

6. Carefully check whether the jewelry has burrs, whether the chain body is straight, and whether the buckles, interfaces and ear clips are safe. When buying gold jewelry, we should pay attention to the use of flux in order to make the buckles of bracelets and the joints of earrings stronger, and the color of the parts with flux should be lower.
