What I prefer to polishing with: Flourite is not something I cut, recommended polishes are wax lap with Alumina or tin oxide or chrome oxide Ultralap. Orient the table about 10 degrees off the crystal face to reduce cleavage problems.

Jeff's Comments: Cuts pretty easily, and can be a tough to polish. Watch the heat when dopping… Typically has silk and cleavage problems

Design Notes: About any designs will work well.
