First, the gold content in gold jewelry is an important indicator of its quality. The national standards have clear regulations on the problem of gold jewelry content, that is, each gold jewelry sold by merchants must be listed to indicate its gold content and weight. The weight of the gold jewelry is all used in the national statutory unit.
. Gold jewelry is divided into 24K with the amount of gold (more than 99%gold content), 22K (91.7%gold content), 18K (75%gold content), 14K (58.33%of gold content), 12K (50%gold content), etc. Essence
. When buying gold jewelry, you can identify from the following aspects:
The color dislike: As the saying goes, gold is "Qiqing, Eight Huang, Jiu Zi, Ten Chi". The experts believe that the jewelry of 70 % of the gold is yellow, and 80 % of the gold is yellow. The pure gold is soft, and it is generally not used to make embedded jewelry. Therefore, all inlaid gold jewelry claims to be 24K and there must be fraud.
This: The proportion of gold is 19.3 grams/cubic centimeter, and the proportion is more related to the proportion. When the proportion is close to 19.3, the higher the pure gold. At 18.5, the gold contains 95%, and the gold contains 90%at 17.8, and so on. As long as the proportion is measured, you can know the color of gold jewelry. But most people can have a sense of precipitation.
Is to see the rhyme: The high -quality gold jewelry will have a dull slap in the cement floor, sound without rhyme, no strength, commonly known as "dead sound". On the contrary, the low -collision gold jewelry is thrown on the cement floor with rhymes and sharp sounds, and a slight jump.
The test soft and hard: the higher the color of the gold jewelry, the softer, and the more elastic. The real gold will have light marks with the teeth or needle. It will change color. Low -colored and fake are the opposite.
