18X7mm Sterling Silver and CZ Clasp. These clasps are generally used for stringing. The holes are not big enough for the jump rings we sell, so they are best used with string or wirewrapping. If you want to add jump rings, you would have to specially make them and solder them closed yourself.

This item has multiple layers of plating on top of a 925 Sterling Silver base to limit color changing. The sterling silver base is first plated with copper, which helps the final grey rhodium layer stick better. It is then finished with a 1-3 micron outer layer of grey rhodium, which is very thick by industry standards.
