Gems in the sunken City

Hi,

I got the first gem from the cute little mermaid, used it in the door in front of this moving room, went to the door that opened, killed the craps and have the 2. tablet. I learned from other postings that the 2. gem must be somewhere near the 4 traps there but I absolutely can`t find it. It was not in the chest where the tablet was inside. So I can`t go on right now. I thought I could take the gem back and open the 2. entrence outside the sunken city but I couldn`t find a way to open that door either.

There are 3 glowstones altogether.
In the cage area after you raise the cage you should find a hole in the floor through which you can swim.

One the mermaid gives to you
one is in by the crab traps
the third is in the room that has the 6 tunnels coming off the side.

Thanx for your answer Wyv. Unfortunately I already read that in other postings and I know it has to be there but it isn`t. I swear! I searched the whole area after the crab traps. I went through the hole that was there after I pushed the buttons in the crab- room. I found one chest at the end of the tunnel in the small room. There was a the 2. tablet inside but no gem. It can`t be there... Very strange and frustrating.
