This behemoth came to me at a local Rock Shop - he was hidden on the bottom shelf, in the back. 5 of us were standing there talking about labradorite when he flashed the entire room - a brilliant beam of blue exploded from him and dazzled all of us. I said "oh my" stepped forward some 40 feet, knelt down and reached behind a multitude of mixed stones - mostly malachite and pulled him out. He actually purred..and I did to.
Teacher stones are rare, this one has shown me worlds and been my confidant.
Includes 1/2 dollar (50 cent piece) for size contrast
