Comment: The rarest of all color changers: a Tanzanian tourmaline. For its rarity in the 'Best' section. As all these tourmalines dark toned, midnight green with red flashes, the rarest and most priced of colorchanges because it moves right across the colorwheel, a trick only very few alexandrites can pull. No muddy mixed color in between but either red or green, even when showing both at the same time, then not melting but simultaneously. Extraordinarily rare collector gem in good quality. We only had one of this type ever. A full report could show chrome and also Usambara. No window, no visible inclusions, no treatments. On the images we had to white-balance the colors to show them clearly, an exception to our photo rules. The comet-like set of inclusions visible under the lens and torch are not visible to the eye. The handshot shows the dark tone as in person. Surely a gem for the collector of the rarest. In jewelry, a quiet friend to look out for these extraordinary color phenomena with patience and appreciation for the understated special.
