Amethyst – Natural, Specimen, Purple
Sometimes during a crystal's formation, a new layer grows over a transparent crystal. When the growth of the original crystal resumes, it's left covered with a "shroud." These inclusions of now indistinct, almost transparent crystals are called phantoms. This amethyst specimen contains pyramidal phantoms.
