Comment: Tourmaline on the rare yellow side of the spectrum. Coming from one of the best German gemstone facetter, this artful cut is never cheap but always worth the extra dollar if you like your gem to be perfect. No inclusions. The color is an earthy greenish yellow, as one might expect from a mature blossom in autumn. See side images showing the green axis of the gem, while the face-up is mainly yellow.
