Gold purchase:

1. Style is an important factor in determining the value of gold jewelry. Style not only determines the decorative function of gold jewelry, but also determines the technological value of gold jewelry.

2. The fineness is the purity of gold. The higher the price, the more expensive it is.

Generally speaking, if you want to pursue higher value, then the brand will be better. Of course, it doesn't mean it's not good.

4. Choose gold ornaments with heavier weight, so that you can make many pieces to wear by yourself.
