Description

First of all I have to note, that this specimen is much better in person - all faces of this razor sharp terminated crystals show brilliant luster and amazing texture, photos just give you an idea of it´s true quality. The crystal is water-clear like cut glass. I show one photo with our label underneath, that should give you an impression of exceptional clarity. The dimension and the diameter of this crystal give a great visual impact to this specimen. One more indicator makes this specimen special: colorless rock crystal is much more rare than smoky quartz from switzerland generally, No significant damages to report and again - much better in person.
