【Polishing Instructions】
*For more detailed and easy-to-understand instructions, please watch the video.

1. After wetting the stone, polish it with a diamond file first. There is no functional difference in the polishing surface between the diamond files (white) and (red). The (white) file has a wider surface, making it easier for children to use. Use it when you want to remove a lot of material. The (red) file is recommended when you want to polish fine details.

2. Secure the waterproof sandpaper to the wooden binder and polish the stone in a circular "no" motion while wetting it. The smaller the number of the waterproof sandpaper, the coarser the grit. Polish by changing from sandpaper with smaller numbers to larger numbers (from coarser grit to finer grit).

3. The process is complete when you have polished it to your desired extent.

 

【Precautions during polishing】

・There is a risk of cutting your hands while polishing. Please be very careful during the polishing process.

・Occasionally rinse off the polishing residue with water and dry it with tissue or a paper towel to check the polished surface. If you continue polishing without rinsing, the residue remaining on the surface may scratch the gemstone. Please change the water as needed.

*One rough gemstone will be delivered.
The photos are examples, and you cannot choose the color or shape. Please understand this in advance.
