A #macro #photograph of an #amethyst #crystal merging into its #rock #matrix. The #deep #purple merges into a #yellow layer, a #white layer, and ending in #green rock. Amethyst is a kind of #quartz, which is crystallized #SiliconDioxide #SiO2 that is colored purple by #IronOxide #inclusions in and on the crystal. This #dramatic change in color took place over an extremely long time.
