Description

First I have to note that this specimen is much better in person. The iron rose developed highly lustrous, razor sharp thin crystals. In the center you can see a tiny quartz crystals and some red rutiles are also intergrown. The assemble and the tri-dimensional visual impact are much better when you hold it in your own hands. The iron rose is set on a small snowy white, small matrix at the base. No significant damages to report.
