This bi-colored Elbaite crystal has a trait to it that I have never seen before. It has the standard hexagonal prismatic form with the equally common shallow, trigonal pyramidal termination, and is in very good condition, with only a few minor "dings", mainly near or on the termination. Its prism faces are heavily striated, but the entire crystal has a vitreous luster and is transparent but heavily internally fractured. The lower half of the crystal is a moderate pink color, and its upper half is a rather deep green with a hint of blue. What confuses me about this specimen is the abruptness of the color change. There is an uneven line that seems to represent a crack running at an angle through the crystal; on one side of this line, the crystal is pink, and on the other side, it is green. There is no transitional coloration whatsoever! This crystal would make an exceptional pendant.
