Alexandrite, Fort Victoria, Zimbabwe (In daylight)
description: 2 3/4" ac. Acquired from Robert Sielecki in 2011. Alexandrite is a variety of chrysoberyl that is green in daylight and reddish-purple in artificial light. This is an outstanding Zimbabwean Alexandite specimen since it sports several sharp sixling twins on a well proportioned matrix. Sixling twins are a trait observed in mineral species that crystalize in the orthorhombic crystal system. The color of this specimen of Alexandrite dramatic and outstanding. I have seen thousands of inferior specimens of Zimbabwean Alexandrite during my travels to southern Africa and this piece was acquired from a lot of around 200 inferior specimens that Robert Sielecki imported into Australia from southern Africa.
