Phantoms Crystals

Phantom quartz is a variety of quartz, or "rock crystal", that, over the course of millions of years, forms over earlier minerals that already existed. It takes its name from the particular structure of its crystallisation: each crystal displays the outlines of numerous smaller crystals, known as phantoms or "Ghost Crystals” they can appear as a complete crystal "within” another or as spectres of colour such as when an Amethyst Phantom occurs in a Quartz.
