Leland Blue is a glass slag, by product from the pig iron factories. It was dumped along the shore to hold back erosion. Now jewelers have found it. It is cut into cabs to be set or drilled for beads. When it is gone, it is gone! The piece is a pear shape and bezel set into a sterling silver mounting with a bail of a nice size for your chain or cord. Designed by Linda. The over all size is about 2 1/4″ x 1″. A striking piece!!
