Amethyst is a macrocrystalline variety of the quartz crystals. Its violet color, sometimes intense, depends on the amount of iron (Fe+3) it contains. In this case, being amethyst geodes, this crystal is grouped into a cavity. Regarding its color, it may be colored by areas with transparent or yellow quartz. The points of amethysts tend to be darker or degraded to the colorless quartz.
