Description

A really fine pseudomorph sample - large, well developed azurite crystals formed this amazing cluster, they are completely replaced by malachite. The crystals are partly glossy and chatoyant - this indicator is much better in person and also the color is more impressive when you see it with your own eyes. No significant damages to report.
