Lighten small sapphire stone

[SapphGk]

I have a mans ring with a tiny sapphire (maybe 10-12points?). The sapphire is very dark and light doesn't pass though unless it's over an LED. Is there an "at-home" method I can use to lighten it? It's set into a 14k white gold emblem which is set over 14k yellow gold. Will leaving it on the window sill on sunny days help the process along?
Thanks

No, there isn't anything you can do.

I was afraid that'd be the case. Not even using a torch to heat it would alter it?

You will melt the gold. Why not just replace the stone if it bothers you? A stone that size can be sourced by your jeweler and will not be very expensive.

I agree with Gene, a 10 point sapphire is very expensive and you are better off replacing it as there's no way to lighten the colour.

Thank you for your replies. I am going to see about this today at a trusted jeweler. I have been dabbling with some old rings and have improved my polishing/restoration skills. I've heated a couple rings to cause a patina and then polished them and performed some scratch removal with a Dremel and Rouge. Just experimenting. I wish I could find a guide on setting stones so I can learn. There are a lot of nice inexpensive stones out there at this size and it'd be a nice skill to possess. I seem to have accidentally stumbled into this and it's becoming a hobby. Not to take anything away from professional Jewelers, but I genuinely enjoy working with jewelry and would like to develop some basic skills. Can anyone point me in the right direction?

If you are interested in learning to set, Blaine's New Approach School or Revere would both be excellent choices.
