As in Chrome Tourmaline! Beautiful rich greens ranging from bright and lively
to deep and velvety make this type of tourmaline very desirable!
An interesting fact: Despite its name, chrome tourmaline's hue is not primarily
caused by chromium. Vanadium is the element that contributes most to
Chrome Tourmaline's highly prized intense green color and is the same element
that gives most emeralds their color as well!
