First of all, gold investment is mainly divided into physical gold, gold T+D, paper gold, spot gold, international spot gold (commonly known as London gold), futures gold, gold advance payment and people's livelihood gold, which are eight popular forms of gold investment. ?

Physical gold, buying and selling gold in kind by buying and selling gold bars and ornaments. Physical gold: in the form of 1: 1, that is, no matter how much gold is purchased in any currency, it can preserve its value, and it can only buy up, but not down, with a large amount of investment and complicated procedures and expenses.

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 it. 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.

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.
