A spectacular large crystal, just HUGE and deeply colored, with multiply-phantomed crystals to a whopping 5 cm (2 inches!). MUCH BETTER In PERSON...when backlit, this piece GLOWS with colors subtly changing from green to blue throughout. It is, like the above specimen, one of the best from here that I have seen for sale and is representative of older material, as opposed to what is being mined here today.
