There is something that has been bothering me ever since I began reading the cheap glass thread that I have avoided bringing up because I really don't want to create a stir about it. I used to be in the clothing industry at the retail level and there was the tendency for one manufacturer to knockoff or copy another as an accepted way of doing business. An expensive dress with the designer name would be given to a local or, usually, a Chinese manufacturer to duplicate. That dress might be sold for 10% to 30% of the retail price of the designer dress. It might be as well made but would usually be at least a little less well-made, but would be within the reach of regular middle-class people rather than just the very rich. It was an accepted way of doing business and the only people that were truly annoyed by it where the designers themselves.
This was duplicating or copying, but not counterfeiting. Counterfeiting is when you duplicate a product and try and sell it as if it were actually the original product and not a copy. That is what these vendors are doing when they put a company's logo on their glass copies rather than leaving them unmarked. As someone said before, duplicating may be considered "the sincerest form of flattery", but when duplicating the label, it is just plain counterfeiting. The idea is for vendors down the retail path to sell the items as if they were created by their designers.
Personally I will not buy a piece that has a designer name on it that I know is not made by the designer. Nor will I order a piece that might come with a designer label on it. That of course is the only way to prevent manufacturers from counterfeiting when their only concern is how best to sell the product they have made and they have no laws or standards that prevent it.
Far be it from me to tell other people how to wear their morality hat, but I thought it important enough to at least mention it in this thread for people to consider. Many countries in the world do not care about original art, patents, and the laws that protect artists and designers. I personally don't think that is a better way, and if you ask one of those content creators you will likely find how discouraging and demoralizing it may be for them, especially if they are not a large company that can more easily absorb the competition, legitimate or not.
So to be clear, I am not in any way discouraging the copying of product whether it be glass pieces or designer dresses. I do think it is important, however, that during the course of our purchasing decisions that we keep things like this in mind. And I think it may also be useful to remind our (in this case) Chinese manufacturers that part of the reason we don't want them putting original designer labels on their product is not just how it looks.
....maybe now they can answer us here 
Did they give you any clue how thick it was? If it is 5mm I may have to own that.
I would definitely order multiple if you had these product!
