A nearly complete Alexandrite cyclic twin comprises this thumbnail specimen. It is in good condition, showing what appears to be a small amount of relatively fresh damage, and shows reasonably good orthorhombic bladed form- though the cyclic twin shows some inconsistencies, it is obviously properly formed. Though its color is essentially black, one can see definite green highlights under fluorescent light that are absent under incandescent light. The crystal is opaque even under bright light, however. It has a rather dull luster that ranges from waxy to pearly. There is no host rock present, and the piece is affixed inside the included thumbnail box.
