Take as many grams as you want, from eight to nine grams to the heaviest.

Pay attention to the following points when buying gold bracelets:

1, if you want to choose a brand enterprise with good reputation, don't be greedy for cheap brands, and the price of gold is relatively transparent, obviously lower than the market price, so be careful;

2. Remember to ask for invoices, which is the core of protecting consumers' rights and interests;

3. Gold can be detected, and the gold jewelry detection institutions under the national technical supervision department are located in major cities, so it is relatively easy to detect the composition of gold jewelry;

4. Choose a regular merchant who promises to buy back, and the quality can be guaranteed. The testing standards of gold products in China are very strict, and the supervision of regular merchants from raw material purchase to storage to processing and sales is generally standardized.

5. Understand the current market price of gold and the factors that affect the price of gold. The price of jewelry gold will fluctuate with the international gold price, market supply and demand factors and other reasons. If consumers understand the influencing factors of gold price, it will be more conducive to buying affordable gold bracelets at the right time.

6. Whether the gold has white highlights, cut the gold bars or gold jewelry with scissors and observe its cross section with a magnifying glass. If you see a bright white spot, it means that gold and iridium are mixed together, because gold and iridium cannot be mixed together.

7. To measure the specific gravity, first measure the weight of a pure gold bar with a balance, then put the gold bar into a measuring cup and pour water to drown the gold bar. Then put the detected gold bars into a measuring cup and observe whether the scale of water rises or falls. As long as there is a change, it means that gold bars are not pure gold. But if it is gold jewelry, this method is not applicable, because there is air in gold jewelry.

8. Real gold is not afraid of fire. Put gold jewelry on the fire for a period of time and observe its changes. Because iridium will combine with oxygen in the air to produce oxidation reaction, gold bars with insufficient purity will turn gray; And pure gold will appear bright red after being baked by fire. However, this method may have some damage to jewelry.
