This style has a heaver sterling disc than its predecessors and an antiqued textured bail to accommodate the hand-hammered copper disc. The diameter is the same as the others and can accommodate the same size buttons. Our adjustable length neck cords of 4mm will fit through the bail opening. The over-all diameter is near 1 ½” (37.4mm) and the diameter of the center copper disk is 1 1/32” (26.1mm). A button between 5/8″ and 1″ in diameter (size of a US quarter) would best fit this mounting. If contemplating a button with a shank that can’t be larger than 6.5mm at its widest point. If the mounting instructions included with the item are followed, no harm comes to the button. This allows the one to change the button for a different look. The pendant bail on this piece can accommodate a chain or cord that is no wider or larger than 4mm US $87.00, INTRO PRICE $72.00. Click on image to enlarge. A neck cord is not included.
