This is worth every bit of the asking price just as a world-class, huge and gorgeous calcite crystal. But when you add the flashing purple and blue chalcopyrites at the top, and PHANTOMS inside, it just amazing! The crystal is complete and perfect all the way around, and from any direction, it shows a dozens flashing sub-terminations. The luster is intense! Each of the "sub" crystals on this compound crystal contains its own sharp phantom. At the top, where the crystal grew against the top of the pocket, it took away a bit of the matrix with it, and these amazingly colorful chalcopyrite crystals (there is one small contact cleavage in this area which doesn't matter at all). 20 x 9 x 10 cm
