Comment: Darker than expected blue green tourmaline from Nigeria. Ever-since the Chinese buy all tourmaline to ward-off Fukushima radiation we cling to any reasonable rough we can get. This turned out to be really dark blue green (the rough seemed more open). However, if you like it dark and want a real gemstone this is a good deal. Giant looks, no window. No inclusions.
