I have one from Altinay but didn't cost anywhere near that. They have one or two on their site right now for much less than that, so I'm guessing the one you're referring to had some other features such as bamboo. Unfortunately prices have gone up across the board though...the currency isn't worth what it used to be.
Whether it's worth any amount of premium or not is up to you. There is a bit of controversy as to what if any real difference there is with this type of block. All I can tell you is that the one I have does have a subtle difference in the surface...as
@didimauw said, it appears slightly transparent on the surface layer...and I do not detect this appearance in any of my other meers. So if you want one, Altinay is the only seller that tells you up front that's what you're buying.
Mine has been coloring very slowly. I've smoked it almost every day, and it's actually been coloring even more slowly than average for some reason. I'll have to post a current pic later when I have time, but the thing is you really can't see the "translucent" aspect very well at all in a pic for some reason...it just doesn't come across...you really have to be looking at it in hand.
This is the stock pic when it was new:
