I put this on a small cross pendant that has a small bail.It is very sturdy,Ordered this for my daughter. Have a large quartz necklace and wanted a longer chain and heavier than the one it came with. It is really pretty and know she will like it.i like this chain. The hook is a little small. a few times i thought the chain was secure but it was not.I’m pleased with this chain. It seems sturdy enough and the clasp isn’t so small I can’t work it.Great buy! It was just as advertised and worked great with my locket. Length was perfect!
