Comment: Deep duck green at day light, changing to an orange red at night, and in some light angle glowing with a fiery blood red. Not to be confused with bi-colored stones. This is real color changer. Quite a catch for the collector of rare earths, but also a one-time-only opportunity for jewelry with a color-change gemstone. Green-Red changer tourmaline is even rarer than Alexandrite (though less expensive because less famous).
