Slabs of Jura Limestone are interspersed with fossilized elements stemming from plant and marine animal life forms. The amount of fossils found on each slab is dependent on the depth of its excavation. Additionally, the stone glass veins made up of quartzite. These calcites are a natural part of the stones geological formation and are, therefore, an inseparable component within the stone.
