Black is not the typical color you think of when you hear the word Amethyst, but this Amethyst includes Hematite inclusions that give it this dark coloring. When inspected closely with a light, however, you'll see that familiar lavendar hue.
Black Amethyst energy is very similar to that of purple Amethyst, but with a highly grounding and Earth connectedness flair. The inclusions of hematite make it extra protective and ideal for intuitive work. Plus, did you see it sparkle?!
