Shine bright like an alexandrite.
Were you ever into mood rings? But maybe disappointed because all your ring ever seemed to tell you was that you were "stressed"?
Alexandrite is like a mood ring but SO MUCH BETTER — it's a gemstone that changes color in different lights.
Observe as this alexandrite goes from blue (in ambient light) to a sparkly purple under incandescent light (as in, from a lightbulb).
Depending on where alexandrite is mined, the stone's color spectrum can vary. High-quality Russian alexandrite can be green in daylight and deep purple or even red in incandescent light.
