Granite slab 12"x18"x4" for $20 bucks... worth it?

[myjtp]

This is my first post but I have been lurking for a while.  I read many times a nice thick piece of granite is the way to go for stamping leather.  I had a guy message me off craigslist with this slab ( pic attached ).  I assume this is a crazy good deal and i should jump on it and he will DELIVER it to my house!  My question is ( probably stupid ) how can i tell if its real granite? Can you guys tell from this picture?

Thanks!

It needs to be smooth with no holes. You should be able to source a sink cutout from a local shop, or a defective headstone or...

unless you have a dedicated place on your bench for that beast, go for the thinner piece from a local shop that does countertops so you can move it when you aren't using it. I got an oval piece for free that is about 9x14x1 from a local shop

Worth it IMHO. 4" thick is way sturdier then the counter top stuff. You can sink it into your bench and it will work great. 

If there are any divets or holes just use a slow setting epoxy to fill it in then sand it smooth with sandpaper and a wood block.

I actually scored this piece for free a few days ago but I was wanting something thicker I can build a workbench around. But will this be good enough?

The piece pictured directly above is actually very similar to the piece I found in a basement at an estate sale with my wife.  I have been pounding on that slab for almost a year with no complaints.  Go with what you have man.

As for the photo above, I wouldn't care if it was genuine granite or not.  That behemoth chunk of stone is definitely worth 20 of my hard earned dollars.  That thing would be more solid than my garage floor when driving a tool over some leather on it.  DO IT DUDE.

And, unlike the sink and counter drops you get for free, no sharp edges that will constantly screw up your finished leather pieces.  those rounded corners are nice!   I'd say get it.

Don't know if that $20 would be worth the hernia from lifting it I am going to go with the others and say that a freebie piece from a countertop place works just fine. And anything that is free is worth saving up for.

I also agree! I got a block similar to that, an unfinished gravestone. I set it into a free workbench I got and it was amazing!!!! if he will deliver at no charge, go for it!!
