This jewelry set combines a large metal casting stone setting, 12x12mm square stone setting with 2mm ball chain around, and a regular 12x12mm square setting.
These large stone settings with 5mm jump rings will look great with round 6mm jump rings.
To open these loops just slide the plier tool inside the loop and strongly press on opposite directions till it opens.
Now you just need press it on both sides in order to close it again.
Have fun creating!
