The title says it all. I found this stone, or crystal, in my yard, and I really like it. I like crystals and interesting rocks. But I would like to know what it is. My best guess, based on its shape, it that it is a geode that had been in running water. It definitely has crystal properties; it sparkles when looking at it from various angles, though the photos don't show it. I'm also guessing that it is smoky quartz. I'm not going to break it open, it is a great stone to hold and play with. It is slightly smaller than a big bic lighter.

Any geologists out there?

I am no geologist, but I too love rocks and crystals. I have a collection of all sorts of different crystals.

One of them even looked slightly like this, except more round like a ball and was rougher looking. Although mine was rougher looking it could be due to not being in running water. It was found sitting under a tree one day in my grandparents yard as a kid. It sparkled in the sun light, and even under normal house hold lighting if held close enough.

Since my grandfather is a carpenter, and has many tools at his disposal, we decided to cut it open with a table saw that was made for cutting tile. Made a perfect clean cut through the center of it. It turned out to have crystal formations on the inside of it, which explained the sparkling effect on the outside. We believe it is just some type of quartz, since quarts is fairly common to find. Its not a very strong crystal formation either, you can easily break off a chunk by simply touching it to hard.

They are cool too look at though, being bright white, with almost a smokey effect to them. Like looking through a clear glass bottle in bight sunlight that is completely filled with thick, dense, white smoke.

I too love breaking open interesting rocks. I found this, which was pretty big, and broke it open with a hammer. This is on of five large chunks, the first photo being the outside (next to my lovely 13 crystal skulls), the second is what is inside.

That looks to maybe be citrine? Or a mixture of that and quartz. I have a few Citrine crystals and those are some of my favorite. I love the color and the shape that they form when its just citrine not mixed with quartz.

The shape of the stone in the original post looks like a fossilized animal dropping. Perhaps a cast of the void left once the dropping has decomposed?

It kinda looks like some kind of fossil to me as well.
That or some kind of quartz matrixed in another mineral.

Where are you? Just like flora and fauna, different types of minerals are present in different areas. Quartz and other crystalline stones pick up various colorations from the surrounding minerals.
Geology depends upon geography.
In Georgia, where I grew up, you can find red quartz in the red clay soil, fir example. If you check out some local geo books, you can find what is common in your area.

I'd have to go with fossil as well. It looks like a fossilized shell of some sort of mollusc. Just a guess

Hey there 112233,

I am a gemologist, jeweler and lapidary (by trade). I agree that this rock appears to be a fossil, although it seems that it has been wholly petrified. Meaning, the original organic life form has been 100% replaced by the mineral which inhabits it's organic appearance and form. So while amber and similar fossilized substances have been transformed through the millenniums, this intriguing stone has replaced the prior shell, entirely.

My guess would be either quartzite or feldspar? Impossible to identify from a picture alone. Regardless, what is most appealing is the state of METAMORPHOSIS. Is this not what we psychonauts are actually undergoing, as well?

IMHO, heightened levels of experience without transformation and integration, are simply a rollercoaster ride into the infinite possibilities of self-aware frequencies of consciousness. May we all crystallize in like manner. Rock on, good people!

I like your crystal skull

Hmmm, yes, that's interesting. I've never considered the fossil angle, but I like it. And thanks Rising Spirit for that explanation, that's very cool.

I always liked to joke that it is a chunk of unicorn horn, or the pineal gland of a dragon. Now how would I smoke this.......that would be totally metal to smoke the pineal gland of a dragon.
