What kind of camera and lens do you use in diamond jewellery macro photography?

To shoot diamond jewellery I use Canon 5D Mark IV and 180mm prime macro lens.

I set up camera for RAW full frame format with pixel duplicating function.

Also you need a light tent to control the lighting. Plus a set of light diffusors.

Usually you have to use different light diffusor setup for different types of jewellery. 

For example sharp edges jewelry needs needs different light modifier than rounded shapes.  See attached pics.
