Loading... Please wait...This is a listing for sterling silver (stamped .925) grommets for lampwork beads. Each individual grommet is stamped with .925 on the outer rim, so that everyone can see that they are sterling silver. The interior hole on these grommets measures 4.4mm and are a perfect fit for the Pandora and other European style bracelets. The exterior of the hole portion of the grommet (the part that would slide into the bead) is 5mm. I use 5/32 mandrels and double dip them, and they are perfect for these grommets; they ideally work on the 3/16" mandrel though.
