Yes, lighting is king, but I recommend using flash. Because there is enough light, you can have enough depth of field and the light can shine brightly.

If you want to express luster and texture, black and white cardboard is very easy to use. You should know the usage of black and white cardboard, where it is dark and where it is bright.

It is recommended to use a still life box. The light can be soft enough. Generally, as long as the light is always the main light, the rest of the effect is created by white cardboard with black background. White cardboard can be used to reflect light, highlight the edge of jewelry and show the outline of jewelry. Flash can produce crystal clear texture. For the effect, you can use a reflector, which is not expensive, about 40 yuan, big enough to shoot jewelry.
