Don,t have the slightest. Where you found it might give someone a clue,general area.

Did you try a 12lb sledge hammer?

Did you try a 12lb sledge hammer?

Yes I did. I also used a hammer and chisel and a drilling kit and I totally destroyed it. Harder than 8. Thinking spinel?

Looks like quartz. What kind of tools did it break?

So you destroyed the 12 lb sledgehammer.
It doesn't show impact marks.

Harder than quartz. Rotary kit. Scratches quartz.

I didn't destroy the hammer, of course, but it didn't do anything to the specimen.

I don't know if this helps but this more grey bit on the side has some kind of greasy, waxiness to it. Does that help?

Looks like quartz conglomerate to me, or at least some type conglomerate.

I agree it's some kind of conglomerate. Any tips how to break it up without totally destroying it?

Rock saw. If you do not have one I would bet someone near you that does cabochons and/or members of a rock, gem, and mineral club have one. Google your area for clubs near you. They will be glad to work with you I am sure. Stop beating on it till you talk with them is my advise.

Good luck and let us know how it goes.

Most the photos are poor quality. Not sure what tools you used that broke, care to elaborate? Quartz, which this looks like, cannot be drilled by standard metal bits. It is about 7 or 8 hardness, you will have to look it up.

Quartz and granite , it's everywhere . I've never seen a rock that a sledge wouldn't crush.

Try a vise.

Try a vise.

Looks like the O.P. is already rockhounding / prospecting. Isn't that a bad enough vice?

Periwinkle kryptonite

I would be very careful with that rock. Periwinkle kryptonite. A non-canonical variety. Exposure to periwinkle kryptonite causes Kryptonians to lose all their inhibitions.
