How do you polish rough tourmaline?
Use a high-grade aluminum oxide polish, about 1 tablespoon polish to 2-3 tablespoons of water, in a slurry. Add a small amount of vinegar to help stop scratches, though that’s seldom a problem. Apply the polish to the lap with a decent-quality watercolor paintbrush made for applying washes.
How do you get tourmaline out of quartz?
The only method I know of to assure the preservation of the tourmaline crystal is done by using a diamond saw to cut away the surrounding quartz. You should consider a jewelers trim saw if the specimen is relatively small or otherwise delicate, and remember that thin blades are generally preferable to thicker blades.
