1. Color identification:

Gold can be distinguished by color, and the colors of gold of different qualities are also different. When gold is red-yellow or yellow-red, the gold content generally reaches 90%. to 95% gold, while the gold content of yellow is generally above 80%, and that of turquoise is around 70%.

2. Sound identification:

Gold can be identified by sound. Gold will have a dull and low sound when it is hit and thrown, and has less elasticity. If it's flexible, make it. If the sound is long and sharp, accompanied by a clanging sound, it means it is fake gold.

3. Hardness identification:

Gold can be distinguished by its hardness. Generally, the hardness of gold is relatively low. Scratching with a pin or fingernail may cause scratches. And when the gold is bent, there will be wrinkles, which are usually fish scales. If not, it is fake gold.
