Shooting jewelry requires high equipment. Generally speaking, for precise control, M files are used. From my personal experience, there are many small apertures for shooting jewelry, because if you use a large aperture, it will be very blurred and the appearance of jewelry will not be clear. Here are some suggestions:
1. Good lighting equipment: at least 2 flashlights.
2. You should have a macro lens of about 100MM, otherwise it is not good to show the subtle texture of jewelry.
3. There should be a still life shed to avoid stray light from affecting the final imaging of jewelry.
