Gorgeous, NWOT, handmade stone PopSocket phone grip. It includes both base and top. It is one of a kind and handmade. FROM THE RETAILER: These are real polished pieces of Septarian Nodules from Michigan Lightning Stones sliced gemstone that have been added to a genuine PopSockets phone grips. These stones have all been selected to fully cover over the top of the 1.5 inch diameter plastic socket. These are real hand polished natural gemstone pieces with a natural black and white and sometimes brown brecciated (crackle fissure) pattern inherent to the stone, so each one is a little bit different. These cabochons have been polished on the top and sides but not underneath (underneath is where the PopSocket is attached). More about Lake Michigan Septarian nodules, also called Lightning stone: They are made when clay combined with an iron mineral called siderite somewhere around 50 million years ago. These concretions are believed to form in part through bacterial activity. They become fractured and the fractures fill with calcite brought in by ground water. The result forms lightning like patterns on a dark background. Septarian stone is said to bring the wearer confidence, patience, and emotional flexibility.
