It might be the Meebo chat bar at the bottom of your page. Unfortunately the premium membership's no-advertisement incentive doesn't apply to Meebo as it is a third-party tool. For this reason, though, you have the ability to disable it:

Thank you TheGrobe for your interest. Your suggestion has worked, so now I do not have to begin looking for any of those cussed jewels!!
That's one of my biggest issues with Chess.com is the massive amount of ads on this site. I recently downloaded Firefox and got the adblocker plus addon, and now I don't get any of those annoying pop ups, Chess.com or Meebo related! it's awesome, and I don't have to pay for a premium chess membership that I don't need!

Adblocker plus for Firefox is an outstanding utility, but there is much more that comes with a premium membership than just getting rid of the advertisements. In my opinion it is still well worth the price of admission.
Where does the 'Begin your quest for valuable jewels' come from. Every time I open the chess.com page this annoying pop-up pops up. Does this happen to anyone else? It is something to do with Facebook.How can I stop it!
