These are natural American Staurolite crystals that were found by me at the GA/NC border. They still have some mica schist and also some teeny dots of black garnet on them which gives them their shiny appearance. They are grouped by size and each one is basically one of a kind. #s1,2,3 &5 all are X’s . #’s4&11 have more than one X on them and are unusual looking. #’s 6&8 have an X with an extra piece of staurolite crystal on them. #7 is a double X with them superimposed on each other. #9 is a piece of staurolite crystal with an X and other pieces of staurolite growing out of it. #10 is a partial X and also a partial cross.
They are also 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.
They can be wire wrapped to make earrings or a necklace. These are the perfect size to use in a fairy house.
