Let's try gemstone polishing "Do-it-yourself rough stone polishing set" (for intermediate users: iolite rough stone)

From requests like "I want to enjoy gemstones up close and touch them," and "Are there any experiences for parents and children?", we created the "DIY Rough Gemstone Polishing Kit".

This rough gemstone has a higher hardness compared to others, making it recommended for those who want to take their time and polish carefully [intermediate level]. We have chosen iolite, which offers pleochroism, and is sized for gemstone polishing. Enjoy the pleochroism from various angles after polishing!

This is a set of tools for polishing rough gemstones and a rough gemstone [iolite].
With this set, you can enjoy the experience of polishing rough gemstones at home right away.

【Polishing Instructions】
※For more detailed and easy-to-understand explanations, please refer to the video.

1. After wetting the stone, begin by polishing it with a diamond file. 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. Please use it when you want to remove a larger amount of material. The (red) file is recommended for polishing fine surfaces.

2. Secure the waterproof sandpaper to the wooden binder and polish the stone in a "no" shape (like drawing a circle) while keeping it wet. The smaller the number of the waterproof sandpaper, the coarser the grit. Please polish by switching 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 hand while filing. Please polish with extreme caution.

・Periodically rinse off the abrasive residue with water and use a tissue or paper towel to remove moisture, then check the polished surface. If you continue polishing without rinsing with water, the abrasive 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 be aware of this beforehand.
