anyone know what type of stone this is? is this a grave marker?

[Dan R.]

Looks like Coast green.

[theresrocksinmy]

Whats a Coast green? Can you please tell more about it

[Dan R.]

Your pic looks like blocks of this in a wall.

Coast green is a stone we used as a substitute for Costa Smeralda about 12 years ago when the Costa was scarce. Not sure of it's origin.

What are you using this stone for?

In rough block form, ConnaMarble from Ireland would be very similar. maybe even identical?!?!

I have to say Dan I'm impressed by this knowledge.

Dan R is The Godfather of the stone industry. thank you for sharing the knowledge Dan!

Thanks.
Happy to share my thoughts.

Don't be too impressed, as I am not sure exactly what it is. I could be dead wrong!
Just giving some avenues for research to find the right stone.

I just found the stone in the wall of the foundation of the basement of a house that is older than 1840 from ohio in the united states. There is a few of them. Its strange because you have all this cinder block then a few of those in the wall. And one guy who is half right haha half of the time said its a grave stone. And I was like I don't know about that. So I looked on google and this forum came up. I do have to vote impressive knowledge on what kind of stuff it is.

The cinder block is only about 3 foot high around the whole house, then sandstone / other block / rocks is under that around the house. It looks like they did it the raise it up maybe.

1840 Ohio. I would think it may be some local stone. Hard telling. It may be that there were some commercial buildings with the same stone & the stone used for house foundations may have been excess from those larger projects.

I doubt anyone on 1840 Ohio imported marble or granite for house foundations.

looks to be in great shape for 170+ years old.

As far as a headstone, what is the size and thickness of it. At that time, there was no standard sizing for monuments, as each was hand cut to each order. At least that is how is was with our company in the late 19th century, up to WW!!.

Fresh (relative) chisel marks would be an indication that it was re purposed. this is not unheard of in many places around the world. People from all over always seem to scavenge usable durable materials like rock.


After looking at the pic more closely, That very well could be a portion of the monument. To me, it looks like a base piece, meaning that an upright tablet sat on top of this. The faint rectangular outline with the chisel marks in the center would not erode, as it was covered by the tablet. the outside 3" was exposed to weather and eroded to a smoother finish. The lower right portion looks like the tablet portion may have been damaged, as evidence by the erosion beyond the straight edge.

Look for apiece that matches the length of the inner rectangle. It may have an inscription on the back side. The side out would probably be more rock pitched than smooth. Although it could be finished, which would be unusual for that era.

Interesting...

There was a update on the house that raised the basement up a bit where that part of the stone shows.. Its only about 3 foot. What year it was done. I honestly have no idea.. maybe 60's?

your knowledge has been amazing so far on this. As for the size its cemented into the wall its a bit less than 16 in × 8 in. thanks again.

[theresrocksinmy]

and I can't view the other side because it goes under the porch which is all cement.

[theresrocksinmy]

I guess my question also is.. has anyone ever seen anything like this before at all? another person said it was just a fancy block. But there is only a few in the basement that I can see of.

[Collier]

I think it's definitely locally quarried sandstone. The largest and oldest sandstone quarries in the US are in Ohio. Cleveland Quarries, Briar Hill, and Waller Brothers. Most foundations in Ohio and PA from the 1800's are Sandstone, I didn't think cinder block was available until the early 1900's. It is very common to find stones mixed in with different marks and of different shapes, as it was common to repurpose things or pull from multiple sources. I supplied a job a few years ago that required using four different types of sandstone to match the existing for an addition.

Look for a piece that would match the dimension of the inner rectangle. The back will be exposed, if it is there. So, the one dimension would be about 12"-14" x 3-4" thick. The height may vary, but probably no taller than 26" or so. If it is re cycled, the tablet could very well be a broken (thus irregular) shaped piece with the 12-14" dimension intact. The 3-4" thickness will be impossible to ascertain, as it will be buried in the wall.

Interesting story. Probably used cinder block on the raising project in the '60's.
