Does a fake diamond cut glass like a real diamond?

I am trying to find a Hydro Turf diamond-cut mat kit for my Kawasaki 750sx jet ski. I looked on their store and all i can find is diamond cut sheets. Anyone know where I can find these?

Does this add any properties or worth to an item? What is so special about being diamond cut, and etc? About the item which i am talking about, it is a mont blanc pen.
