Comment: Spectacular tourmaline in neon green-blue. The images catch its color and precision cutting in exact detail and as in person. No inclusions. No window. A high-end gem in ring size. Close-to, or as good as, a classic paraiba tourmaline. It has long become clear that the amount of copper in tourmaline does not run parallel with color-quality. Some Mozambique tourmalines bring on the full magic of a paraiba without crossing the threshold for copper-content in testing, while some copper tourmalines remain dull. Not cheap but no-where close to the usual paraiba-ask. Six mm round will fill ringsizes upto 7. Color between blue and green, leaning more towards blue IMO. Pretty perfect.
