SWMBO has an item of jewellery that hangs on a bracelet. Problem is that the clip holding it keeps on spreading and allowing it to fall off. I know I can get a jeweller to fix it, but, can I solder it using a soldering iron and normal Pb based solder, or must I find some silver solder, and "braze" it like in bronze welding?

p.s. MODS: Couldn't decide which forum to use, so feel free to move me.
