I would seriously spend time at some flea markets or antique malls, to search out a few vintage stones. Use your fingernail to test how fine the stone is. I got dozens of stones for a pittance of their value-Washita, hard & transluscent arkansas, etc. if real greasy, probably not a natural stone. Look for a fancy, carved case-meant the owner valued the stone.
These used stones pretty much ready to go with a bit of cleaning. For lube, get some Marvel Mystery Oil or some Norton honing oil and have at it.
