Description

The photos don´t do justice to the specimen - all faces all around are highly lustrous. Looks like a disco-ball when you see it in person. With only moderatley backlight color becomes even more intense, seems to glow inside. Really a spectacular, eye-catching specimen! And it is really a complete sphere with only small contact at the bottom. Hard to photograph, much better in person. No significant damages to report.
