Crystal Vase

The Crystal Vase is a Treasure found in "A Tangled Web" of Sly 2: Band of Thieves. It isn't booby-trapped, so it is fairly easy to get back to the safe house. It can be sold on ThiefNet for 546 coins.

Physical description
It is a translucent bluish-white Amphora-type vase.

Location
If you go to the top of the main building inside of the fence, you will be able to see that while facing the fence, there is something glowing at the top of it. This is the treasure.
