The most fundamental difference between gold and gold is the difference in gold content, and the difference in gold content has caused other differences, such as color, hardness, and value preservation.
1. Different gold content
Because the gold content is different, the two will also be different in color. Generally speaking, the more gold there is, the darker the color will be. The color of gold is a little lighter than the color of gold, which means that the color of gold is more yellow.
3, the hardness is different
The purity of gold is higher than that of gold, the price is more expensive than that of gold, and the value of recovery is higher, and the space for preservation is larger.
