We've went from 4C to 37C to 0.7C over the last couple of days. The Windows, Furnace, and Air Conditioner all thing the humans have went crazy.
Funnily enough, our Air Conditioner is set to hold the temperature at 24C.
I think you should set up a little fan to cool your jewels. Be sure to leave them exposed with the fan on high whenever you think the Good Lady is awake. If you can angle the wind so that it blows over the jewels, then continues on to the good lady's face ... that might help with the window situation ... especially if a little flatulence occurs. OR.... that might result in the jewels being processed through the fan blades. Either way, it would be amusing for us readers. ;-)
I have set up a little fan!! It's an old fan I took from a PC so happily for me the blades are held behind a cage to avoid precisely that sort of accident. Hehe.
We don't have Aircon in this country. There is little need apart from one or two weeks a year and then we throw open the Burglar's doors!!
