[For adults] Let's try gemstone polishing "Do-it-yourself rough stone polishing set" (for beginners: bicolor fluorite) with boulder opal *Subject to the rough stone polishing contest*

The `` Do-it-yourself rough stone polishing set '', which has been very popular every time it has been released, will be sold again with new contents.

This time, the stone chosen for the set for adults is bicolor fluorite . Because of its low hardness, it is easy to polish even for beginners, and each piece has a different striped pattern, making it a fun piece of jewelry to look forward to. Just like last time, the set includes all the tools necessary for polishing jewelry , so you can start working on it right away.

Additionally, as a Christmas present from Karatz, adults will receive an Australian rough boulder opal as a bonus . I was given a very old old stock by a local businessman. Please try to find the play-of-color effect that is typical of opal, which shines here and there.

I hope you will experience the beauty of gemstones while you are at home during winter vacation or the year-end and New Year holidays.

▶How to use a loupe

[Explanation of how to polish]
*Please watch the video for a more detailed explanation.

1. Soak the stone in water, then

First, polish it with a diamond file . There is no functional difference between the diamond file (white) and (red) in terms of polishing surface. (White) has a wide surface and is easy for children to use. Please use it when you want to make a large cut. (Red) is recommended when you want to carve detailed surfaces.

2. Fix the water-resistant paper in a wooden binder and polish the stone in a ``no'' shape while soaking it in water. The lower the number on the waterproof paper, the coarser the texture. Polish while changing from paper with a small number to paper with a large number (from coarse paper to fine paper).

3. Polish it to your liking and it's complete.

[Precautions when polishing]

・When sharpening, there is a risk of scratching and damaging your hand. Please be careful when polishing.

- Rinse off the abrasive that comes out while polishing with water from time to time, remove moisture with tissue or kitchen paper, etc., and check the surface being polished. If you continue polishing without rinsing with water, the polishing agent remaining on the surface may damage the surface of the jewelry. Please change the water accordingly.

*You will receive one rough stone.
