Alexandrite is the rare color-change variety of the mineral chrysoberyl. Its rarity is a result of its unlikely chemical makeup. Alexandrite displays the color change phenomenon because trace amounts of Cr3+ has substituted for Al3+ in the crystal lattice. This substation rarely takes place making alexandrite extraordinarily coveted.
