2mm Chain End a 2mm chain end that is available in 14kt yellow and 10kt yellow. With quality in mind, our chain ends are manufactured in Italy. The chain end allows the jeweller to have an ending on which a jump ring and or clasp can be attached, thus allowing proper closure. Our chain ends are made to be bent and pinched (adapted to your particular style). These chain ends must be soldered to the chain. Different widths are available in order to match to the chain width. For example a 6mm chain end would work with a 6mm chain or may be adapted to fit a narrower chain.
