Cutting Corundum cuts and polishes at varying rates on different facets. Dont cut with a bonded lap at any finer grit than 600, otherwise an orange peel effect will make polishing a nightmare. Pre-polish with 8,000 grit on ceramic, zinc or copper lap helps speed up final polishing immensely.

Polishing Ceramic with 100,000 or 200,000 diamond spray, or zinc lap with 50,000 or 100,000 diamond. BATT can be used as a polish lap, but is a little soft for corundum.

Comments Orient for best color and yield. Corundum cuts and polishes differently on different facets.
