This thumbnail specimen consists of a few intergrown Alexandrite crystals. These crystals are in very good condition, showing no fresh damage, and have a good orthorhombic bladed form. Under normal indoor light, the crystals appear to be nearly black in color and opaque. It is only under a very bright incandescent light or under sunlight that one can see a rather faint translucence. Under the incandescent light, the crystals have a dull, red-violet color, and under sunlight, their color is a deep green. Their luster ranges from waxy to greasy. There is no base or host material present, and the piece is affixed to a flat acrylic base with a removable putty.
