These are beautifully cut and polished Septarian Spheres from Madagascar. A sphere is a round ball-shaped crystal shaped from a much larger piece of crystal. This shape emits energy equally in all directions. Septarian is unique in that it is formed as a result of volcanic eruptions and attracted dead sea life, chemically bonding them to the sediment and forming mud balls. They are composed of calcite, aragonite, and limestone. As the balls dried they shrank inside and had a tendency to create a distinctive pattern of 7 points in every direction. Septarian is also called Dragon Stone or Dragon's Egg because many people have come to know of the egg shape with black druzy crystals inside as something that looks like a dragon's egg. A grounding stone, Septarian allows for better tolerance and patience, as well as emotional flexibility. Small spheres weigh 50-150gms each. Medium spheres weigh 200-280gms each.
