Don't know if this link is what you had in mind (this one looks like cut stone). If not, this is from the Fireplace Xtrordinair site & there are lots of other pics.... Here is a link that might be useful:

I know this doesn't really help, but we bought a stone mantel directly from a manufacturer in California - but I am sorry I don't recall the company name. We paid 1/2 the price that mantel direct charges. I do know that there are MANY manufacturers all over, so do a search for "precast mantels manufacturers " or "architectural stone manufacturers" and other search terms. We were very pleased with our mantel - shipping from California to TN. The freight was around $300.00 and we needed about 4 men there to move it - all and all though, it was half the price!

Thanks kippy, yes my mom is going to make cushions. Pal I guess you're right about the floor but the old fireplace covered the floor corner between the hearth and the wall. So it is unfinished wood. So it would be less work to cover it back up again and I think if I stained/varnished it that it would never look completely right anyway. What do you think of the style I posted? My house is a typical McMansion neo eclectic so it doesn't have a lot of style direction one way or another. Annie everyone I've spoken to about the crown thinks that I would for sure have to do the whole wall over and possibly the whole room if I mess w the crown. And I'm not thrilled with the look right now anyway. Though taking out the rough hewn beams and lion heads lightened things up, the whole space feels so so heavy to me.

Sorry, but that is 'stone' that is made using light weight concrete. If you touch it, it might feel like stone but it's not. You can add a mantle. You can purchase them already made if you like on Amazon, but the hard part is that the wood has to be scribed to the face of the stone and that will take a skilled carpenter to do that. Here are some options to bring the room out of the 70's. You can Limewash over the stone if you would like a lighter tone.
