Sterling Silver Open Jump Rings

PLEASE READ DESCRIPTION BELOW :
Sterling Silver Open Jump Ring - un-soldered, open, smooth

** Please note that a jump ring can be described by it's inner dimension and/or its outer dimension as well as its thickness (gauge)
Example : If you have a 4mm jump ring (outer dimension) that is 18 gauge (1mm thick) , then the inner dimension is 2mm
Below you can see each jump rings description. So if you have a 4mm jump ring from another supplier (who calls out the outer dimension) , Here it will be called a 2mm (inner dimension) x 1mm (thickness ) in the drop down menu.
