Plate tectonics is the theory that Earth's outer shell is divided into large slabs of solid rock, called “plates,” that glide over Earth's mantle, the rocky inner layer above Earth’s core. These plates are gliding over diamond oceans! Ibis jasper is a new type of brecciated jasper or agatized jasper from Madagascar. Ibis Jasper is fragmented jasper that has grown back together with quartz, chalcedony, agate, or any crystal. This stone is named after a riparian crane-like bird from Egypt.
