Create Gemstone for rendering

Is there a easy way to create the facets needed on a model of a gem for rendering. Tried converting to mesh but could not come up with the right settings.

Hello Et_Rec,

Below i is a link to a tutorial on how to build a diamond:

Thank you. Very useful. I usually measure a stone for the job, and make a quick loft to help visualize the job. I wish there was a passable way to convert to mesh just for rendering.

Hello Et_Rec,

Can you please explain why you need to convert your model to a mesh before you render it.

Thank you, Andy

The gem models I make have no facets. That’s what make a Rendered gem look real

Don’t know it this will help or not here is a .zip file that has at least fifty gemstone drawings for Rhino.gemstones.zip (232.0 KB)
All my best Danny
