One of the world's rarest and most fascinating gemstones throughout history is the alexandrite, a gem variety of the mineral chrysoberyl which possesses a "night-and-day magic" that changes the color of the stone from a bluish emerald green in daylight to a warm red with hints of orange in incandescent light.
Alexandrite has a distinguished and glamorous past having been first discovered in 1830 near the Takovaya River in the Russian Ural Mountains on the occasion of Czar Alexander II's 21st birthday, and was thus named alexandrite in his honor.
Alexandrite can be found in jewels of the period as it was well loved by the Russian master jewelers. Victorian jewelry from England also featured sets of small alexandrites. Mining in Russia lasted less than 100 years and reached its peak in the late 19th century. Alexandrite was then later discovered in Ceylon and Tasmania.
This exceptional stone is cut to allow the play-of-light and to capture its phenomenal powers to its fullest extent.
