This question was asked on another forum. Apparently it was dug up by a potato harvester.

Is it a potato? They sell red potatoes at our local Morrisons that look a bit like that and they take some boiling. 😉

Looks like a pretty nice piece of carnelian to me (red agate) If so, should have a hardness of 7 (same as quartz) Where was it found?
Carnelian is found at Wheal Cock and Marazion in Cornwall

Where there's a mine or a hole in the ground.
That's where I'm heading for that's where I'm bound
So follow me down Cousin Jack

Almost certainly this a sample of red Jasper.
It it is found from Cornwall to Shetland.
Carnellan is orange, more translucent and of course rarer.
Agates usually are banded this is not.

It was found in Shropshire.

Looks like Hematite....Any idea of size / weight / Spg. grav?
Hematite is fairly heavy and dense, and the colour, as far as this photo shows, is about right too.

Dont think Hamatite, this looks to have a bit of a polish like its got a high hardness, sort of gemmy look to it. Easy to tell that anyway nick it with a grinder...

Looks VERY like red Jasper from the Lleyn (North Wales)

"Found in Shropshire"
You didn't find it on my wall did you ! 😮
I will be checking! :smartass:

Looks like jasperoidal silica. Basically chalcedonic quartz with micro-inclusions of iron oxides (both haematite and other gel oxides).

Thanks for that, very helpful, and to everyone else who replied. The chap did send a photo to the NHM. Their reply:

The NHM has got back to me and suggests it looks like Jasper or glass cullet chunk - I really don't think its glass cullet since I have seen that before. Either way the guy said both are not usually found in Shropshire so would have transported here by man or nature. He said there isn't many minerals with such a deep red colour.

It reminds me of stuff we used to get out of burn't out pit tips, not only red shale, but sometimes harder rocks where caught up in the intense heat, did it come from close by a reclaimed colliery? Or even a foundary?)

Always remember, nature is in charge, get it wrong and it is you who suffers!.

I don't really know but it was around Worfied if that's any help.

I'll go with Rufenig and John Lawson on this one - jasper. Loks too vitreous to be hematite. Maybe pushed around during the ice ages ?

It is jasperoid NOT jasper. Jasper would be opaque and have a different texture. Both are chalcedonic gel silicas but this sample is definitely jasperoidal silica.

Definitely NOT haematite.

Been to Mynydd Carreg today. Strange mists coming in from the SW. Thought the quarry was at the top of the hill, guarded by bullocks, spent a lot of time exploring outcrops with vague purple bits. The quarry itself is actually quite low down, and has huge chunks of jasper. Very nice. I notice jasper isnt a registered mineral on AN?

Followed up with a trip to Nant Ysgo to pickup 'manganese minerals' which turned out to be black bits of rock, presumably with manganese in it.
