These are very pretty, and can be used as a pendant with the pre-drilled hole, or do as I would do and glue a rhinestone in the pre-drilled hole, then use it as a cabochon to bead around!! :) These have a completely flat back and are carved in front for a three-dimensional effect. The entire Star is outlined with silver and measures 37mm across. Imagine a necklace and bracelet set made with these.....WoW!!
