- Chrysoberyl Var. Alexandrite
- Miniature, 3.7 x 2.7 x 1.5 cm
- Malashova Mine, Ural Mtns., Russia
Alexandrite is the rare and valuable color-change variety of chrysoberyl. This sharp, well-exposed 2 cm-across crystal is emplaced on a micaceous schist and exhibits typical moderate luster. The edges show translucence along with divergent red and green hues that show very strongly in different lighting (halogen vs fluorescent). Overall, this is a very respectable, display quality miniature from this historic gem crystal locality.
