This is a Bat pendant made from genuine polished Picture Jasper gemstone. It measures about 1 1/4 inches wide by 1 inches wide and comes with a black adjustable cord necklace. Note that each gemstone is a natural stone formation so no two pieces will be identical, however, each Picture Jasper pendant will be unique and have a beauty of its own. Jasper is an opaque rock of virtually any color stemming from the mineral content of the original sediments or ash. The various patterns arise during the consolidation process forming flow in the silica rich sediment or volcanic ash. Picture Jasper is a petrified or silicated mud that dripped into gas pockets in molten lava. It became superheated and then solidified forming the unusual banded patterns which are typical of this stone. It also aids in visualization and meditation. Whether you purchase this pendant for its beauty and geological formation or for its metaphysical characteristics, you will be sure to appreciate it.
