6x20mm 14K Yellow Gold Flat Marquis Charm with Jump Ring. These charms are perfect for engraving, stamping, or wearing as-is. Please keep in mind that these charms are completely blank, and are not stamped with a 14K hallmark. If you need a 14K stamp on your finished design but cannot engrave on your own, the easiest solution is to use a chain or clasp with a hallmark.
