This crystal of gem-clear quartz, which has been polished along its faces to give a better into its interior, contains a wonderful phantom crystal! It is made extra easy to see and well-defined due to a sprinkling of some unidentified mineral on the faces of the phantom, clearly delineating its outline. Phantoms form when a crystal stops growing, and then is enveloped by a later generation of growth. Sometimes they are very difficult to see, unless, as in this case, something happens to be deposited on their surface . . 8.2 x 3.1 x 2.5cm
