Comment: Dark as sin. Otherworldly ultramarine greenish blue in this Indicolite, a rare variety of Tourmaline. The wide brilliant cut gives us a serious diameter of 8.5mm, able to fill even a big sized gent's ring. Fascinating colour play in sunlight. Not black in low light. There is one inclusion but it is hard to find even under the lens. IGI certified, unheated, no window (too dark for that). Precision cut but the round is a hint oval if you can see it, hence no 'excellent' in cutting grade though this will not be visible after a setting. Special bargain for a special ring.
