Electroplating thousands of gold is gold plating, using copper or some common materials. It is plated with a layer of gold, which has the luster of gold, but it is easy to fade and the price is not expensive. There are dozens of gold-plated men's necklaces, and the price of agate is also very cheap. A string of agate bracelets is generally ten or twenty pieces, and dozens of pieces are better. However, your three 200 yuan models are not expensive either. You can have fun, but don't be a baby.
