Tourmaline (multicolor and doubly-terminated) with Albite (ex Tom Campbell Collection)

Item Description

A wonderful polychrome Tourmaline crystal from the most famous Tourmaline locality in Pakistan. I have seen many Tourmaline specimens from Stak Nala for many years and the one characteristic of that many of them lacked was decent color. This attractive DOUBLY-TERMINATED crystal features several colors ranging from a colorless "Achroite" basal termination, then a beautiful yellow-green color which gives way to an olive-green color, and a very dark (almost black) green hue throughout the prism which is capped off by a vibrant pink pyramdial termination on the other end. The crystal has great luster on the terminations and the prism faces, which is not common for this material. The final touch to the piece is an attractive "flower"-like "rosette" of white, bladed Albite (var: "Cleavelandite") flaring off of the Tourmaline. PLEASE NOTE: The piece is repaired, so please keep this in mind when bidding! Great quality and form for the material. Valued at $1750 retail. From the worldwide collection of Tom Campbell.
