It's not one of the usual Crystalex pieces we see. They have more going on than in this piece. The surface treatment is different, for example. The Crystalex pieces have areas where the piece has almost been irridized. I've not seen enough of Suhajek's other work so I can't say if this is or isn't by him. I'm quite sure it's not part of the common Crystalex series, though. Writing to him seems the best option.
