A customer has just brought in these 'earrings' . He inadvertently put them in the fire with the wrapping! They were well and truly roasted.
They are 9ct white gold and Tanzanite with a tiny diamond at the top.
Can anyone advise me about cleaning white gold? I have tried but the colour is slightly yellow and looks pitted. Also 2 of the Tanzanite stones are cloudy so I think they are damaged. One 'diamond' also has lost its sparkle.
He is hoping I can either mend the earrings or take out the stones and put them into something else. He paid £150 for them - so not cheap.
To mend them I will have to remove all of the stones and re-attach the components somehow. Not used to working with 9ct white gold.
In your opinion(s) do you think it is worth a) mending them, b)putting the stones into something else or c) tell him not worth it.
Also, is it possible to solder sterling onto white gold? Is it ok to use silver solder?Click image for larger version.  Name: P1040232.jpg  Views: 62  Size: 42.8 KB  ID: 4151
