These settings are beautifully designed to securely hold Swarovski 4754/S Starbloom Fancy Stones, and come in three different versions: 00 C is unplated with no holes and a closed back; it’s predominantly used for soldering and post-plating jewelry. H2 O comes in three plating variants: unplated, gold plated, or rhodium plated, with holes and an open back, and is largely used in sewing. 1T O shares the same three plating options, but the ring on top and open back lend it to hanging projects (rather than sewing), and make it especially suitable for DIY.
Swarovski 4754/S Starbloom Fancy Stone settings are made of either brass or tombac. Standard platings include Gold and Rhodium.
