how to make a diamond material

Is there a tutorial on how to make a diamond material for blend4web? I need to do something like this https://www.blend4web.com/en/demo/jewelry_3d_configurator/

Or if anyone knows the proper settings, please share your knowledge about this! It would be greatly appreciated

Thank you so much!

Hello and welcome!

We have a diamond material in the library (in PRO), so if you're serious about using Blend4Web in your projects, purchasing a PRO license sooner rather than later perfectly makes sense.
