Re: How to polish labradorite?
I have worked up about 20 pieces of labradorite this fall. I have gotten a great polish using the following method. I use these steps for all softer stones and achieve good results. After grinding out the preform, 1. sand with a worn out 220 grit belt, 2. 600 grit belt, 3. 1200 diamond belt, 4. 8000 diamond belt and 5. final polish is with a 50,000 diamond belt. The diamond belts that I use are 3M brand, kinda expensive but last a long time if you recharge them with the appropriate mesh diamond spray. Labradorite is a stunning stone if you can learn how to cut the slabs at the correct angle to expose the color. Every piece of rough is a challenge. I'm still working on achieving consistent results with the slabbing step of the game. Good luck.
