Missing one item and 1 jewel

[llanita]

I am missing the very top right item in Treasures. It's a yellow orb on a stand, and I don't which island it's from.
I am also missing 1 yellow jewel from Monkey Island, and I've looked at the monkey island tutorial, including the monkey island gems tutorial, I've also changed the background color of the jewel several times and still can't find it.

I am at a loss.

That item is on Guardian Mood where you will be able to go after you find that last gem.

Ok thanks, but I cannot find that last gem.
The utility says I'm missing a yellow jewel on Monkey Island, and the rainbow says I'm at 99%.
I have scoured that island several times, the jewel background is colored a bright red, I have viewed both the Videos on Monkey Island a couple of times each, and that gem is not on that Island.

I have version 1.02

Ok, I finally found it. I had to destroy all the buildings and it was behind one of them. I thought that any jewel behind a building would show up regardless.
