My parents have 3 or 4 of these, on the ground they look like button mushrooms or even eggs (I get caught everytime). If it's some sort of geode I'd be curious to crack it open, it is rather heavy for it's size. But I'd hate to open it if it's just stone. It is very smooth and it hasn't been tumbled by me at least. Petrified egg? It's about 1" or so across  |

Hey Tweetie, It's not an egg. Contrary to popular belief, petrified eggs don't look much like and egg. They normally look like humpty Dumpty fell off the wall and all the Queen's men put him back together again.
Around here, rocks that acquire that shape naturally are usually the softer rocks. Things like Dolomite, Marble, that sort of thing. In rivers and streams they can become very round and are often that same color and texture.

ps.
You might try and see if vinegar reacts with it. If not, try scaping a little powder off and see if that reacts.

What will the vinegar do? - it does have a rather hard surface - haven't tried scratching it yet - getting kinda attached to it lately... *mother hen, covering her eggs!*

Hey Tweetie, I use Muriatic Acid (Hydrochloric Acid) but vinegar is a mild acid as well. If the rock is Calcium based it will react and bubble off Carbon Dioxide. Dolomite will only do it if powdered.

Should I take a chance and whack it open? - what am I losing really, may have a surprise inside - some sort of deadly powder  |

That's pretty neat, didn't you ask your parents where they got them? I'd be dying to find otu what's inside ... ;D but I don't know if I'd want to whack it either. Please let us know what you decide to do.

Be careful if you do whack it open. I did one on the side walk the other day and it bounced back and smashed my finger. I have one I would love to open but can't make myself do it. It's funny that we become attached to rocks.

You can also put some water on it and see how quickly it absorbs the water. I had a rock similar in looks and texture, and when I went to wash it it litterally soaked the water up and then when I checked to see how hard it was I first tried to break it apart and it literally fell apart in my hands. I don't know what it was I just tossed it under the pine tree.

Tweety,
I have no idea what it is but it looks so nice, I'd just keep it as is.
