The universal symbol for womanhood was use as an 18th-century botanical sign. This setting is specially designed to accommodate the Female Symbol Fancy Stone, and comes in three versions: 00 C is unplated, with no holes and a closed back, and is mainly used for soldering and post-plating in the jewelry segment. H2 O is the opposite: it has holes and an open back, but it comes in three plating variants: unplated, gold plated, and rhodium plated, and is primarily used in sewing. 1T O has the same three plating styles, but comes with a ring on top and an open back, making it perfect for hanging, rather than sewing, and particularly useful for DIY projects.
