Natural stone beads Chalcedony (Quartz) 6mm matt Multicolour Dark Brown

Our popular natural stone items are scientifically investigated by Hanco Zwaan, mineralogist at the Dutch Gemstone Laboratories in Naturalis. During this research, it became clear which type of rocks the beads are made of. The editing process of the items was researched as well, so that we can tell you exactly what materials your natural stone collection is made of!
This item consists of chalcedony. That means the bead actually is made of natural stone and a coating or paint has been added. The solid form of the rock has not been altered. It is said that this type of natural stone has a calming effect.
