When you go to a jewelry shop and you notice the jewelry that is free to touch and wear, it gets really dirty and damaged and loses its beauty, you don't always need the shop keepers permisson to try it on but then theres that special jewelry at the bottom, behind the glass cabinet inside the special casing, to wear that jewlerry you need to get the shop keepers permission and he'll watch you the whole time making sure you don't do anything stupid like damaging it!

So whats the difference between the jewelry on the top? and the jewelry behind the glass cabinet inside the casing?
