If you're having trouble opening the jewel box, try this:
To open the jewel box follow this pattern: 1st number the jewel spaces, start at the top one as # 2, and count up clockwise until #8, needless to say the jewel space to the left of #2 is called #1. Once you do this, do the following. Start with #4 and move jewel to #1, then start on #7 move to #4, then start on #3 and move to #6, then start on #8 and move to #3 then start on #2 and move to #7, then start on #5 and move to #2, finally start on #8 and move to #5. This will unlock the jewel.
