The real Vietnamese placer gold is basically equal to gold, but its gold content is slightly lower than that of China gold. But the most popular Vietnamese placer gold on the market is actually copper-plated 24K gold, because its electroplating is vacuum-plated 24K gold, which has a long color retention time and is not easy to fade, and it contains real gold, and the test also contains real gold.
24K gold-plated jewelry refers to electroplating a layer of 24K gold on a certain material (such as silver, copper, lead, zinc and other alloy materials). The gold used for gold plating is not pure gold, and there is no 100% pure gold in reality. 24k is the color code of gold products. 24K gold is often considered as pure gold, but the actual gold content is 99.998%.
