[On sale from 10pm on 6/19] [Koshu Precious Stones Plusthree] Synthetic Moissanite 12mm/5.570ct Loose Stone Patch

Moissanite has a hardness of 9.5, second only to diamond, which has a hardness of 10, and a higher dispersion rate than diamond, sphene, and demantoid garnet. It is actually quite a suitable mineral for jewelry. It is extremely rare for it to be produced naturally, so the ones that are commonly available are synthetic gemstones. This is also synthetic moissanite. Moissanite comes in a variety of colors, so it's fun to collect them. Please enjoy this dazzling sparkle in your hands.

This is a collaboration piece with Caratz for the new Koshu Precious Stone Kiriko Plus Three Type by Yoichi Fukazawa, the creator of Koshu Precious Stone Kiriko . You can enjoy the intricate and detailed reflections of the glass from any angle.

Moissanite has a high hardness of 9.5, making it a Koshu precious stone cut that is extremely difficult to polish, with the final polishing (process of adding luster) taking a full day for two pieces.
