Hello all, this is my first post since my return to Orchid 1/4/99
looking forward to participating again now I am not so busy.
Heat treated topaz.
Does anyone know if there is a residual danger of radiation with
such stones in particular topaz sourced from Thailand. We have 2
sky blue topaz from there which was reasonably cheap and am
wondering ifthey were safely irradiated, any would be
greatly appreciated.
Diamond.

the girdle of brilliant cut diamonds. eq a serial number.
Best wishes from New Zealand.
Gerald.
