Amazing Adventures Around the World

I am having a problem figuring out what to do on the final puzzle. I think a lineup the gems on the wheel. And then what. I am really stump.

Any help is truly appreciated.

Thanks.

[b]I am also at that point and can't seem to figure it out. I will ask prpldva about it and she if she has played it yet. She is a true gem when it comes to these games.
