Comment: Apple green tourmaline with a fine dense crystal. Classic shape and full size. Zero inclusions, no window and untreated. Great luster from a deep cut gem (see two handshots below, one in shadow, one in light). With 86% depth, this gem needs a high domed ring setting, there up to size 10 or, better, a pendant for which simple four prongs would allow an open and airy design. Excellent cutting visible in side image. Powerful color without blue, and just the right amount of yellow to enliven the green under full light. Not to be underestimated in size 10x9mm.
