Finally got the time for the scratch test. It appears to be the same. Similar look, and feel. Would you agree?

Yeah I would, had it been hindustan it would have gouged a lot more. And you would have commented on how soft it felt :D
Doesn't look quite like a Purple slate (Llyn Melynllyn) to me, but maybe it looks different in the hand than in the photo? Here's a few shots of mine for reference:

Dry, wet, and with slurry. The purple tinge should be fairly apparent as in the last photo, I don't know why the camera didn't pick it up in the first two. I've also got a Black Welsh slate that imparts a better finish, and the old Salmen's Yellow Lake (The English translation of the Welsh 'Llyn Melynllyn') was another good Welsh slate finishing stone that was often grey/black and commonly found with green splotches if I remember right. Those fellas are hard to come by, and I regret letting the last Salmen's I saw up for auction get snagged out from under me. :rant: :cen
From BHW1980's pix, the lighter, pepper-surfaced stone looks like a Washita or soft Arkansas. The slate looks nice. Maybe a UK Cambrian silkstone? Doorsch might know...
Nah, the slate isn't a silkstone. The other stone may be a Washita.
Without key identifiers slates are near impossible to give a location to. As a rock it appears worldwide and in just about every colour combination you can imagine. For a silkstone variant I would want to see a sleeve and have dimensions that are imperial, and common to other silkstones. Most are in the region of 8x2x1 or 8x2x1/2.
There is absolutely nothing stopping that stone been a locally found stone in the USA. Or an imported one. The only thing you can do is test it and be happy to call it a slate of unknown origin.

Got them lapped last night 3-4 hrs for the big one ouch.
Now I'm questioning if they are the same,
1. Color - smaller is clearly white, while the big one is really yellow. Age?
2. Slurry - small one produces what seemed more of a green ( I'm sure the sandpaper played a role as to the color but should have been the same)
3. Time to lap - the small one lapped real quick, seemed softer.

Silkstones usually have a slight amount of "figure" in the surface (like chatoyance with certain woods) in addition to the other identifiers (cardboard sleeve or box and most are 8" x 2" x 1" though there are smaller variants as well). Sawmarks are also often distinct.
The slate in question could be anything. Vermont slate, Dragon's Tongue, Llyn Melynllyn, Yellow Lake, etc. Could be a no-name slate too.
