    It's something to treat with caution - but most chemicals are, really. It's very effective on accumulated gunk in rings, providing there's no stones that won't handle it.

    Great thanks, if it doesn't go back I might give that a try.
    Thanks for your help.

    Seems its probably the gunk keeping it together.

    This was my worry!

    Thanks all for for your guidance. I have just finished it. I soaked in some boiling water and then blasted with my household steam cleaner, then had another go at heating and low and behold no more gunk bubbling up..phew.
    I burnished the cracked bit down and held in my third hand, used some easy 18ct solder i had lying around as couldn't find any 9ct easy.
    It's worked to solder down the little crack that had curled up and have polished out the surface scratches and hopefully she can wear again for a while (until new cracks appear no doubt!).

    Oh well done Maria - I think I might have ducked this one (after a bad experience with something similar!)

    Congratulations, Maria. A satisfied customer and a reprieved husband.
    Hope you don't get a flow of these now. Dennis.

    Oh gosh I hope not!
    She was over the moon with it and they've said they'll have me re-work into something new when it comes to it =)
