Matters needing attention in buying gold jewelry:
1, weighing. If the object is gold, it feels heavy, which is what people call "gold falling into the hand", and vice versa.
2. Look at the color. Pure gold will shine brilliantly in strong light, which other metals, including copper, do not have.
3. Review phonology. Gold jewelry was thrown on the ground with a plop sound. The falsetto is sharp and bright, jumping higher than gold.
4, folding soft and hard. Gold has the characteristics of good ductility and low hardness. Pure gold is very soft to fold, and copper bars are very laborious to fold.
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 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, so as to make the joint between the clasp of the bracelet and the earrings stronger, and the color of the part with flux should be lower.
