Amethyst is a variety of Quartz, mined from geodes or crystalline clusters, all across the world. Amethyst gains its colour from the presence of manganese and iron found in sections of clear Quartz. Its hue can vary from pale red-violet to deep violet, depending on the iron content, and may vary from transparent to opaque.
We recommend that you do not roll your semi-precious stone dice on a surface harder than they are (i.e., glass or wood tables). We suggest you roll them in a dice tray to prevent possible chipping or breaking. See more about caring for Semi Precious Stone here
