First of all, you need precious stone materials such as shadow purple jade. There are several sources. First, bt hs sw dropped, (basically impossible, the trade union will take it away, and you may get it if you go to the sw team). Second, you can buy it yourself in ah, usually 30-40. Third, you can change with your own brand. The gem merchant 15 on the right side of the entrance of Shacheng New Island is a brand.

Second, if you want to cut gems, you need to find jewelry processing. Generally, you can cut gems and money for him, and then you can only get several kinds of gems in fb. I forgot my name. Boss got it in yxfb, and it's basically a mess. You can also buy finished gems directly on ah, generally ranging from 40 to 80.

Third, if you want to set gems, press shift+ right click on the equipment. If a gem has been set, it will overwrite the original gem. After the gem is set, you can't take it out. Be careful. Some jacks have extra properties, and gems can only be effective if they are completely matched. That's basically all. Besides, you are fs, so am I, haha.
