Natural stone beads Calcite with marble look 8mm Ruby Red

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 calcite with coating and is impregnated and coloured. The natural properties of the rock are still present, but the solid form has been grinded to a powder form. The powder is mixed with resin or glue and poured into a mold to be able to guarantee quality. The pure form of the natural stone would possibly be too weak to hold shape without any altering. It is said that this type of natural stone has a calming and motivating effect.
