Comment: Rich deep blue-green (not 'neon') tourmaline from Afghanistan. Free of inclusions. Big face, no window. 80% depth give the colour strength but do not produce a heavy belly in this cut. Classic and precise cutting from Germany. IMHO, such quality is the future of coloured gems: durable, clean, untreated and fully coloured (why? because there is not enough emerald to go around, and all the fake colours will be dead cheap industrial material).
