A professional jewelry custom shop with its own designer. If you have good ideas and ideas, you can tell them and they will show you the design draft. Nowadays, most people go to a custom-made store to buy jewelry, or they basically choose some styles in the custom-made store to directly set loose diamonds. After all, you can see the effect when you have a ready-made style. A friend of mine got married some time ago and accompanied her to a jewelry custom-made shop called Clayan. There are many styles of ring holders in their house, all of which are ready-made. They also have their own designers. My friend drew a sketch for them, and the effect was good in the end. There are many custom shops in the city center, each with its own characteristics. How to customize and choose depends on your own preferences.
