Hello,
I purchased this stone on ebay on a whim. I've become interested in natural stones
and would like to start using them.
When this stone showed up I got excited as it turned out to be a 7" x 1.5" x 1.5" stone.
I would like to identify the kind of stone it is. The first picture shows the bottom
of the stone. The second picture shows the top of the stone after I lapped it
with sandpaper.
I tried it on a chisel and it appears to cut fast. It can create a burr very fast.
Do you guys have any idea of what it could be?
Thank you,
Rafael
