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

"Do -it-yourself gemstone polishing set " was born from the request of our customers who wanted to have fun touching gemstones up close and personal, and wanted something that parents and children could experience together.

This gemstone is harder than other gemstones, so it is recommended for those who want to polish it carefully and take their time [for intermediate users] . We have selected iolite in a size suitable for polishing gemstones, so you can enjoy its pleochroism. After polishing, please enjoy the pleochroism by looking at it from various angles.

This is a set that includes tools used for polishing rough stones and the rough gemstone [iolite].
With this set, you can enjoy the experience of polishing raw stones right at home.

[How to polish]
*Please watch the video for a more detailed and easy-to-understand explanation.

1. Place the stone in water, then

First, polish with a diamond file . There is no functional difference in the polishing surface between the (white) and (red) diamond files. (White) has a wide surface, making it easy for children to use. Use it when you want to sharpen a large area. (Red) is recommended when you want to sharpen a fine surface.

2. Fix the waterproof paper to a wooden binder and rub the stone with water, drawing a "no" shape. The smaller the number of the waterproof paper, the coarser the grain. Polish the stone by changing from the smaller number to the larger number (from coarse to fine).

3. Once you have polished it to your liking, it's finished.

[Points to note when polishing]

・When sharpening, there is a risk of cutting your hand and injuring it. Please be careful when sharpening.

・When polishing, rinse off the abrasives that come out with water from time to time, remove the moisture with tissue or kitchen paper, and check the surface being polished. If you continue polishing without rinsing with water, the abrasives remaining on the surface may scratch the surface of the gemstone. Change the water as needed.

*You will receive one rough stone each. Please note that the photo is an example and you cannot choose the color or shape.
