Frequently Asked Questions

• Q: What sanding sheet should I use for hand sanding gemstones?
  A: Diamond sanding sheets are the best choice for hard gemstones — they last much longer than silicon carbide and maintain consistent cutting performance. Silicon carbide wet/dry sheets are a more economical option for softer stones and general stone work.
• Q: Can sanding sheets be used wet?
  A: Yes — wet sanding is strongly recommended for stone and lapidary work. Use water as a lubricant to reduce heat, extend sheet life, and produce a better surface finish. Silicon carbide wet/dry sheets are specifically designed for wet use.
• Q: What grit should I start with for hand sanding a rough stone surface?
  A: Start with the coarsest grit needed to remove existing scratches or saw marks (typically 120–220 grit), then work progressively through finer grits (400 → 600 → 1200 → 3000) before applying a final polish compound.
