Formed approximately 100 million years ago, this gorgeous stone had complex beginnings. Decomposing sea shell life killed by volcanic activity, had a chemical attraction to the surrounding sediment forming mud balls. Over time, decomposed Calcite filled cracks in the mud balls and crystals formed. A then wall of Calcite transformed into Aragonite, dividing the clay exterior from the Calcite centers. Because of this dividing wall (Septum in Latin) the geodes are called Septarians.

Amber, brought to international attention in the movie Jurassic Park, is a fossilized resin that fell from gigantic prehistoric trees 40 million years ago. Probably the earliest gemstone to be worn as jewelry, Ancient Greeks worshipped amber and included it in their mythology, considering the internal fossils and impurities gifts of the Gods. Many pieces have fossil inclusions. These rare preserved flora and fauna fossils have provided scientists with invaluable information.
