This a natural piece of American Staurolite crystals in matrix that was found by me at the GA/NC border. There is some mica schist and also some teeny dots of black garnet on it which gives it the shiny appearance. There are several staurolite crystals in this piece and it's small enough to display anywhere. It measures 3 x 6 x 8cm.
This is the state crystal of Georgia. The legend goes that when Jesus died on the cross that the angels and fairies cried and their tears turned into crosses when the hit the earth. They are also believed to have metaphysical powers.
