Silver base for 12mm Round cabochon

This is a silver coloured base which has space for two 12mm round cabochons to be attached- back to back to make a bead. The base has a raised seam around the edge so once the cabochons are glued in place- they look like part of the base. It also has a hole it can be strung. The base was made in Germany and you will need to buy the cabochons separately as they are not included.
