This is not a natural stone. I think it's a plastic bracelet. It's light and the colors are beautiful. For some reason, I really like these colors. Even with real natural stones, the colors often differ from the photos, and many of them are just not quite right. I think the second color is the closest. The third photo is for color reference only; the bracelets shown are not included! Please understand. The bracelets are only the first and second photos. The thread [elastic] may be loose, so please restring it. The quality is about the same as a toy, so please consider this before purchasing. Popular item! First come, first served! This is a used item, so please refrain from purchasing if you are sensitive to such things.
