Crackled Quartz and Sterling Silver earrings.  All decorative metal beads and the hooks are made of sterling silver.  I have used both clear quartz and beads whichhave a light blue tinge and contain many seams which give them extra interest.  These earrings also come with little rubber backs to reduce the risk of losing them.  The approximate length of these earrings from the top of the hook to the bottom is 42mm.
