I, ACQUIRED THESE JEWELRY ITEMS, AND SOME COINS FROM AN 81 YEAR OLD MAN, HE SAID HE HAS HAD THEM FOR SOME 50 YEARS PLUS, I AM UNSURE OF THE MAKER, BUT DID TEST IT, TO BE SILVER. IT IS A VERY LARGE STONE, AND IF ANYONE HAS ANY IDEAS ABOUT THE MAKER IF IT IS NATIVE OR NOT, OR IF I AM CALLING THE STONE WRONG, PLEASE LET ME KNOW. I WILL BE LISTING OTHER SIMILIAR ITEMS AS TIME ALLOWS. MANY THANKS; GEORGE NALL
