The crystal shows steel-blue color and the translucency is so good, that it didn´t need any backlight to make these two photos. There is a small intense red-purple zoning along some edges and also at the end-point. Further there is a small horizonatl crystal in this most inetnse purple color at the end-point. A very ey-catching color-combination with lustrous faces. No significant damages to report.
