The most sensational feature about this stone, however, is its surprising ability to change its colour. Green or bluish-green in daylight, alexandrite turns a soft shade of red, purplish-red or raspberry red in incandescent light. This unique optical characteristic makes it one of the most valuable gemstones of all, especially in fine qualities.
It is rare to find alexandrite weighing over 0.25 cts. Stones less than 0.50 carats can be worth several thousand dollars at retail prices. Stones over one carat may retail for ten times this amount, and stones over three carats may cost up to $100,000. Fine large alexandrite, above five or six carats is extremely rare.
