Counting all of the Alexandrite crystals that are embedded in the host rock of this hand specimen would take too much of my time. There are at least 50 that are visible, and I would guess that many more are embedded in the schist matrix. They are generally in excellent condition, as only 3 or 4 are damaged or broken, and the largest of these has visible dimensions of 0.5 x 0.4 x 0.2" (1.3 x 1.0 x 0.5 cm). Though almost all of the crystals are either intergrown with each other or mostly obscured by matrix, several have noticeable and reasonably good orthorhombic prismatic or tabular form, with moderately well-defined edges and clean faces that possess a pearly-to-vitreous luster. One of the crystals, though broken, has even formed a cyclic twin that is at least 75% complete, and may be totally complete (see the close-up image). All have a deep forest-to-emerald-green coloration in fluorescent light or sunlight that changes to a dull red-violet or even red-brown coloration under incandescent light. Opposite the main formation of crystals are several smaller Alexandrites that are sticking out of the matrix- I believe that there are larger crystals underneath these.
