A jewelry factory that has been working for a long time won't lie to you, but there are some exceptions.

I suggest you do this,

First, what style do you want to make? You can design it yourself first, or see if there are any styles you want on the Internet.

Second, when asking for a quotation, you should have a bottom in mind. You know, the current price of gold is around 270, which is an original price. Estimate the weight and then count all kinds of processing costs. If it is lower than the estimated quotation, it is recommended to be cautious.

Finally, maybe you can find a piece of processed jewelry that may satisfy you.
