Look at printing. If it is a gold jewelry product, everything will be printed with gold or thousands of gold. This is the national requirement that gold jewelry needs to be printed, mainly by going to a regular jewelry store to buy and watch the printing, which is generally true. But there is a problem that it is not obvious whether the gold content can meet the requirements of gold. This method can only rely on regular jewelry stores. The density of gold is 19.32, just a little bit, with a heavy feeling, not fake. If a gold ornament looks big and feels 1 0g, but only1and 2g, then the gold ornament may be fake. This method is based on experience, and people who don't understand it should not use this method.

Generally speaking, when real gold is thrown, it will make a dull sound of "poof, poof", which has no charm and elasticity. Gold has charm, sound and elasticity. The greater the elasticity, the longer the charm and the worse the quality. The sound of fake gold is generally a "Dangdang" sound, and the sound has a lingering feeling, and it beats violently after landing.

True gold is marked with sharp objects, which will not break after bending, while fake gold or low-grade gold will break easily. Look at the color, color: Many people know that gold can be divided into pure gold, k gold, real gold and fake gold according to its color. Generally, pure gold with a color above 95% can be called pure gold; The color of yellow is about 80%, which can be called real gold; About 70% yellow can be called k gold; About 50% gray yellow can be called fake gold. Check the official symbol of gold. Generally 999 or 990, or 10K, 18K, 22K, 24K. Anything below 10K is not considered, because the gold content is too low.
