About Amethyst: The inclusion of Manganese produces the lovely purple hues of Amethyst, the content of which determines the relative darkness of the purple (more Manganese a deeper purple, less Manganese a lighter, lilac color). Amethyst usually grows in geodes, which are hollow rocks with crystal-filled interiors. The surface of the interior is called Druze, which is a term used to describe a natural layer of crystals formed on the crust of a mineral, like, for example, the inside of an Amethyst geode. From the outside, Amethyst geodes often look like ordinary rocks, but inside they contain a wonderland of crystals.
Please note: Over time, Amethyst will fade in direct sunlight.
Size: Approximately: 11" x 8" x 1.5".
