Comment: Once again, this natural tanzanite beats the heated standard blue versions that gave tanzanite its original trade-name. This gem shows blue, purple, green, violet and all mixes thereof plus all tone and hue combinations imaginable. See the two side-images from both sides: one sky-blue and purple, one deep violet-blue, plus the backside shots with green and lavender pink added to the show. While the heated blue gems can be magnificent in their one color, many feel they lack life. With 88% depth, we suggest a setting that will allow you the full view into the side to enjoy the many colors. See in the hand-shot below: left in green-blue, while the right side shines in violet-purple luster. No inclusions, no window, no treatments. The three 'nos' of a quality gem.
