Worthless, just beautiful. Gold plating means that brass or alloy is plated with a layer of gold, and gold is plated with thick gold. It is better than gold, which makes it look better as an ornament. The price of gold varies greatly, but as an ornament, it is more beautiful and fashionable than pure gold. Generally, fake gold is gilded, so you can rub it on the ground to see if it will fall off.

Burn the jewelry to be identified (don't melt the jewelry), and observe the color change after cooling. If the surface is still golden yellow, it is pure gold. There are two kinds of gold plating, one is homogeneous material and the other is heterogeneous material. Homogeneous gold plating refers to gold plating on the surface of gold ornaments. It means to improve the brightness and color of jewelry.

Gold plating of heterogeneous materials refers to gold plating on the surface of non-gold materials, such as silver plating and copper plating. Its meaning is to replace the color of electroplating materials with golden luster, thus enhancing the decorative effect of jewelry.
