Well De,
My first thought was 'Geode'.
Does it feel light for its volume? Geodes are
usually hollow with crystals inside.

The safest way to find out what is inside is
to find a person with a 'rock saw' and have them
slice it open.

>>>
A geode is a geological secondary formation within sedimentary and volcanic rocks. Geodes are hollow, vaguely spherical rocks, in which masses of mineral matter are secluded. Wikipedia
>>>

There are gem clubs which would have the necessary
diamond bladed saw. Or, when the gem show comes to
Virginia Beach I would try taking it down to the show
and see if there isn't a booth which sells and cuts
geodes - and see how much they would want to cut it
for you.

I have bought a couple of geodes, and my favorite
method is to have the guy cut it twice. Cut a slab
off one end (to give the other halves a nice flat
surface to stand on) then cut it in half. Makes for
a nice display piece (if it has nice crystals inside.)

Pretty picture. http://cdn-s3.touchofmodern.com/products/001/651/826/abe9183ed2c973f1d5c91426805dce60_large.jpg?1571271948

At some point long ago, I dug up an interesting rock - shown below. What you can't much see is that the rock is covered by flat, highly reflective stuff that I suspect is iron pyrite. But it's not the yellowish "Fool's Gold" pyrite I became so familiar with when I used to spend time in the rivers near Sacramento. This stuff appears silver. For some reason, the shiny parts don't show up in my photos as other than 'white.'

What I'm wondering is how best to break the rock in two without making it crumble. I imagine that there's some technique that's better than just smashing it with a sledge hammer. How do they do it in rock stores? A saw? Light tapping? I'd appreciate any practical suggestions.
