Maybe it's my age or maybe it's my monitor but I really can't see it well enough to even make a guess which is a shame as I enjoy these rock identifying threads!

Is there any chance at all of bigger pictures? please

It is cold but i tried a magnet i have on it and nothing. No magnetism at all. I was interested in if enyone knew what kind of rock it was. No biggie. Thank you everyone for your opinions.

The Experts are here, can't do much with the photos provided. If OP is really interested in identifying the rock we'll need better pictures.

If it's Jet it will leave a brown / black mark if you rub it across a rough surface like cement

Edit to add
You can also do a pin test on it,
Heat the end of a pin and push it into the stone, does it go in? does it smell of anything?

here in florida we have agatized coral it can be may different colors including black look close at it see any astrik looking shapes on it? not sure if thats what you got there or not it kind of looks more like foslized bone. i have done road work and seen lots of base or shell rock as you called it. and yes its from florida. i hunt arrowheads alot of them in florida are made of agatized coral we dont have many types of local stone. hope this helps

I took some pictures of what I have, you can see if it resembles any of them...it would be hard to determine which stone it is, especially with the pictures you have being so small!


media.abovetopsecret.com... ...click ATS pics!

A lot of Jet jewellery isn't actually made of Jet though, I guess it depends how sure you are that it was Jet in the first place

its a black stone used in jewllery over near where i live i think, theres not many places its found in abundance, bet yeah it looks like unpolished jet to me



You must be in my general area (somewhere near Whitby ... I'm the other side of the moor) because as far as I know that is one of the few places where we get Jet from ... in fact I thought that stretch of coast was the only place you can get Jet from.

I tend to go against the Jet route myself because it looks a little bit too smooth whereas Jet appears more cleavaged ... like coal ... but could be wrong (it's been known to happen before)


I'm more inclined to think it's some form of Tektite ... from the pictures shown it could have metamorphic qualities which would support the heat that would have been involved with Tektite as a meteorite residue (the smoothness) ... but if that guess is correct it would be metallic ... can't tell from the pictures if it's metallic ... failing that I'll go with obsidian (again because of the metamorphic look to it ... and of course the colour)

if its coral...it will have a network of tubes or tracks...much like an ant hill "cut away view"

Here is a coral knife I have

files.abovetopsecret.com...

but it can come in black...and it has viens....for lack of better words....

I would agree with you that it's unlikely to be Jet.

I also like the word cleavaged and intend to start using it in everyday conversation

I grew up in the Sarasota area, thus my name here, LidoBeachJesse. I agree that your rock has a good chance of being fossilized bone. Florida has a lot of fossils. I have a similar "rock" on my desk, only it is larger and easier to identify as a fossilized rib bone. It is black and heavy for it's size. You might try the South Florida Museum, www.southfloridamuseum.org and see if they can help you.

Didn't I read on the snow thread that your girlfriend has been held-up at the airport due to the weather ... I think the sooner you get her picked up the better my friend ... love it ... it is a great word though isn't it ?

You are correct I've only my cats for company at the moment.

For the OP there is a little ebay guide here that might help you discern what your rock is
