Can I get away without removing the stones

[Caro]

I have this really lovely little band ring in 18ct gold. It's bead set with tiny angelskin coral cabs and diamond chips. It's very delicate and needs some TLC.

It had to be cut off so I need to close the band again.

I've never soldered 18ct but if I use a gallon of thermogel to protect the stones will I get away with it? Otherwise I'll be looking for someone with a laser
