Vivid Green Chrome Tourmaline · 4.60 ct
Afghanistan · 4.60 ct
Chrome tourmaline takes its colour from chromium and vanadium rather than iron, which is what puts it in the same green register as tsavorite and emerald. The same chemistry keeps the crystals small, so a stone of any size in this variety is worth more than it looks. Afghan.
