Monarch Stone International found a recent  news article that discusses the quest for drilling deep into the earth’s mantle.  Scientists hope to retrieve the deepest types of rock ever extracted from beneath the seabed.  The plan is to set a drill rig in the Pacific Ocean, somewhere near Costa Rica.  Monarch Stone International is known for sourcing unusual and beautiful stone from quarries near and far, just not sure about access to one that is 6km below the ocean floor!
