Alexandrite is the rare green variety (can be gemmy) of chrysoberyl that exibits a color change in natural and artificial light from green to amethystine (Alexandrite effect). This rare and excellent specimen features six-ling twin and macle twin alexandrite crystals aesthetically set next to each other on sculptural biotite schist matrix from the Carnaiba Mine of Bahia, Brazil. Both crystals are sharp and lustrous and exhibit the typical pleochroism characteristic of alexandrite - the color change of green to purple or red.
