There is a reason most chess sets are made of wood. Other materials like metal, glass, or stone feel "cold" to the touch and most players simply prefer the feel of wood. If you were buying it for display, then that is a different story, but for actual use I'd say bad call. Also most of these aren't really stone, but stone dust mixed with epoxy; tha's not necessarily a bad thing but many owners have an inflated sense of their worth thinking they're really hand carved stone. Just because something looks old doesn't mean it is. Folks are real good at making brand new "antiques".
Sorry to sound so negative, but you asked for an opinion and I gave it.
Hello,
I wanna buy a new chess set and I just found really interesting and good looking one. But I'm not really good on meassuring the prices dor those things.
Do you think it's worth to get?
