High-Quality Mixed Spinel 6mm, Inner Diameter 15.5cm These spinels have a very lovely color. They were displayed on a collection shelf, so they are in good condition. However, as they are natural stones, please refrain from purchasing if you are overly concerned about imperfections. I am an individual seller, so I would appreciate it if those who understand this would consider purchasing. ☺️ I am also selling other natural stones from my collection! I hope you will take a look. ♪
