Is anyone familiar enough with stone to tell if this is granite, marble, or soapstone? I don't think it's soapstone because it doesn't take scratches from a finger nail, it does sand pretty easily though, which I'm not sure if granite would do. It was in ugly shape when I got it initially, it had some deep rings (indented in the stone) from where a candle stick was probably left on it for years - I was able to sand those out fairly easily with some 80 grit paper though. Currently it's at a 220 grit sand (did 80, 120, 150, 220) so I'm wondering next steps. If it's granite do I have to sand it up to 2000 grit to get it to darken up, or can I leave it rough and rub some mineral oil on it? All help is appreciated. Pic related is after rubbing it with a wet cloth

Here it is dry at 220 grit

it looks like marble to me, usually marble will be softer than granite thus causing it to scratch abd sand easier. when we polish stone we will go up to 3000 with pads but if all you have is sandpaper 2000 will be good. its also a good idea to clean it with acetone inbetween pads to clean it well

sounds good, thanks for the info. Is a liquid sealer needed at that point?

its not necessary, depends what youre using it for. sealers are usually for countertops or tops where you know youre going to get lots of liquid on. the problem with sealer is its pretty expensive for a one time use

Contractor here.
I've polished a few countertops.
It looks like Marble. You can get it looking like a mirror if you get some sanding pads and a Makita.

then you're good. You could wash it and seal it, but I think sealing stone is a gimmick.

it's limestone. the large flying saucer shaped thing toward bottom right is an oyster fossil (as are most of the other ones, including shard)
This would have come from an intertidal zone (brackish) are of a shoreline.

It's not necessarily a gimmick, for some granite countertops it definitely is because slabs will be resin filled before they're shipped but stone like marble it can help with kitchen and vanity ware

Also good tip with the car polisher and microfiber cloth, that'll get it shining like a mirror
