Brown stone tile-like thing found amongst my grandad’s things

Looks like a whetstone but I don't think I've ever seen one with partial holes like that so I may be way off
Thanks for your reply. It is about the same shape and weight as a whetstone but I don’t think that is what it is. The surface is very smooth and the material is not the same. My dad has actually said he thinks it’s made out of Bakelite, not stone as I first thought.
My father had something similar. He said it was a solitaire game played with marbles. He said he teach me how to play but I was a kid...
Thanks for your reply, Pigeon_from_Hell, I wondered if it was a game, but it is very small; it would be hard to move the pieces, the part where the dents are is only about 5cm sq and not deep enough to support pegs. And it’s very heavy, not a great design for a travel game 🤷♀️
It looks like those scratch stones to test jewelry and such for authenticity. Soft metals like gold and silver leave a mark (grind off a minute amount of the metal), but the stone is harder than other metals and doesn’t scratch or mark when it’s different, less-rare metals.
Edit: [here are some examples](https://www.google.com/search?q=gold+testing+stone&client=firefox-b-1-m&prmd=sinv&sxsrf=ALeKk002a_4wtBYx5iioH_xQ94n0ftHqMw:1598080563858&source=lnms&tbm=isch&sa=X&ved=2ahUKEwi0yNKCoq7rAhWWFTQIHY6yDMkQ_AUoAnoECA0QAg&biw=375&bih=545)
It also looks like a die for a drill press. You would clamp this beneath a board you’re drilling through, and drill the hole through your piece and into one of the holes. Multiple holes allows you more options when lining it up (using the other holes as reference to the drill hole’s position). My grandfather is a carpenter and has similar things attached to his drill press.
Thanks for your reply! I don’t think the material is abrasive enough to be a gold testing stone, but the drill press could be a feasible idea. Sadly, I can’t find any similar examples of this online...
