【Polishing Instructions】
*For more clear and detailed instructions, please watch the video.

1. First, soak the stone in water, then polish it with a diamond file. There is no functional difference between the white and red diamond files in terms of polishing surface. The white file has a wider surface, making it easier for children to use. Use it when you want to remove a larger amount. The red file is recommended for polishing finer areas.

2. Fix the waterproof sandpaper to the wooden binder, and while wetting the stone, polish it in a "no" shape (like drawing a circle). The smaller the number on the waterproof sandpaper, the coarser it is. Polish by changing from sandpaper with a smaller number to sandpaper with a larger number (from coarser to finer grit).

3. Once you've polished it to your desired extent, it's complete.

【Precautions when polishing】

・There is a risk of cutting your hands while grinding. Please polish with extreme caution.

・Occasionally rinse off the abrasive produced during polishing with water, pat dry with tissue or kitchen paper, and check the polished surface. If you continue polishing without rinsing, the remaining abrasive on the surface may scratch the gemstone. Change the water as needed.

*One rough stone will be delivered.
