Description

What a fantastic crystal from more recent discoveries. It shows fantastic luster and the saturation of purple color is among the very best world-wide. And it is not just a single crystal - it shows a wonderful contrast with the addition of light violet lepidolite at the lower third and at the bottom. The photo only gives you an idea of luster and intensity of color - in person it is simply breath-taking! No significant damages to report, barely visible repaired.
