This is a simple collection of 3 commonly used gem shapes for Rhino (round, oval, and emerald) . The gems are available for Rhino 6 and above. They may or may not work in Mac (please let me know if they work in Mac or not, I would like to know).
Check out my profile because I also have free and paid versions of a full gem library for Rhino. And I have free and paid versions of a full jewelry CAD kit for Rhino. (Always try the free version first to make sure everything works good on your computer, especially if you have a Mac or version 6 of Rhino. I have made all these on a Windows computer using Rhino version 7.
