This is a giant 10 x 8 x 7 cm crystal, perched on a natural stalk of stilbite matrix. It masses 1600 grams. The crystal is complete, and starkly geometric like a drawing from a textbook - rare in this size. It has a faint greenish hue to it, more evident in person and not exaggerated or even emphasized in the photo. Obtained directly in about 2005, from an Indian dealer.
