alexandrite
Green-to-red stone
Alexandrite is a rare gemstone prized for its dramatic color change—green in daylight, red under incandescent light.
A variety of chrysoberyl, it ranks among the most valuable colored stones.
The alexandrite in her ring shifted from emerald to ruby as she moved from the window to the candlelit table.
