    Default London Blue topaz color after ring resizing

    Hi,

    I guess it's dumb question, but I try to ask anyway
    I wanted to resize sterling silver ring with London Blue Topaz in it. I covered the stone with cooling paste, soldered the seam. After removing cooling paste I noticed that topaz turned almost colorless, very light blue shade. Is it possible to recover the color of London Blue topaz? Maybe reheat it without cooling paste, will it work? Thank you!

    I Don't think anyone here would know, but I don't think it would work. They start off clear and are turned blue by irradiation. Your best remedy now would be to unset it and replace it. Dennis.
