Gemgen includes the following operators:

Add Gem

Add > Mesh > Gem — creates a new parametric gem object at the 3D cursor with the default cut type (Round).

Set Good Proportions

Resets crown, pavilion, table, and size parameters to balanced, jeweler-standard ratios for the current cut type. Available from the Gemgen panel in the N-panel sidebar or Object Properties.

Reload Gemgen Addon (development)

Press F3 and search for Reload Gemgen Addon to hot-reload the add-on from disk without restarting Blender. Useful when developing with a junction/symlink install.
