Comment: Classic shape for any tourmaline (rough tourmaline is found in long staff-like crystals, mostly). The finest indicolite can scare paraiba tourmaline to splinters, but this 2.52 here in a hint too dark for that challenge and needs full light to show-off. When it does though, as in our images (under natural light, indoors, window-side, no sun), the show is a fine one. This unique sprinkle of green in metallic blue makes for a indicolite-only hue, as fascinating as the famous 'brand-names' like pigeon-blood or kashmir-blue, only more affordable. No inclusions under the lens, simple but precise cutting and good size compete with some grey under-tone, cutting the price down but doing not much harm. As all our gems, it comes with full lab report and grading papers, so your grandkids will one day know they own a real gem and not a worthless synthetic mutant or a cooked-up wanna-be gem that had been on the unregulated market when grandpa bought it 50 years ago. If you keep your paperwork, the grandkids will also know that you helped fighting climate change and cruelty against animals. At 'Medium Dark 75' this indicolite does never black-out in full (the black stripes are a result of the cut) and it does not loose color even in dim light-settings. The shape calls for a pendant with dignified, non-flashy beauty.
