I have seen hundreds of those rocks with pits/divots in them. Often, the rocks are "living" <-- that is, still part of the base rock.

Anyone that wants to find some can go to Roeliff Jannsen Kill in upstate New York. There are stones inside many of the pits, being swirled around.

This is not to say there are not actual man-made pits/divots, but you can find hundreds of them in that particular stream alone.

Crystal Skulls...

I've always wanted a crystal skull in my mineral collection but I could never find one that I could afford that appealed to me. I did finally manage to acquire one but it is not made from quartz — this one's Iron Pyrites.




Missed including a size comparison but it's about two by two inches, weighs about three pounds.

I found this "pretty green rock", that's what the lady called it, at an estate sale today. It was really really dusty from being on a top shelf for many years. I asked her what she'd take for it and she said, "would you pay a dollar for it?" It weighs 9.5 ozs.

Well, Did Ya ? Pay a whole dollar or did you work her down to 50 cents ?

Easily worth a buck, MM.
Could you tell me if it has a green streak or a white streak? (you recall the 'streak' thing from the garnet, right? I don't think this one will scratch your plate, though)
Kinda looks like Olivenite.

I tried twice, now I have two scratches on my plate. These are deep too, you can feel them with your fingernail. The scratches were white. The lady told me her father was in the army and spent some time in South America during the 1980's drug wars. This may have come from there.

I broke down and paid the whole dollar. I was feeling generous!

Whatever it turns out to be that's a beautiful specimen. I'd buy that for a dollar.

What?!
Wait, is this a standard unglazed porcelain plate? Steak is a Standard Test for discovering what a mineral is.
If it streaks white, then it's not Olivenite.

The area with a circle appears to be a crystal in the matrix. Crystal structure is another clue for identification.

Crystal Structure.jpg

The arrow is pointing to what appears to be galena, and it looks like there are several more inclusions elsewhere on the specimen. Sometimes you can narrow down what it is by what inclusion are in the sample. And one of the major clues is hardness, I always start with glass, does it scratch glass, if so, then does it scratch quartz, if so does it scratch tungsten.

BF -- That sure looks like galena to me.

I wonder what the Nike swoosh is just under the red oval... Looks like it probably is a fossilized baby dolphin.

Yes it's a standard unglazed porcelain plate and the green scratched it deep. The green also scratches glass deeply. The gray seems a little softer and it leaves a whitish residue on my plate. The gray is actually a yellowish gray color in person. The green is made up of many Hexagonal crystals.

It's a small spot that's almost black and it's the only example on the whole rock. Looks out of place.

Could this be corundum? It looks like the thing has tabular crystals. Try and see if it's triboluminescent when you strike it in the dark with your porcelain plate.

Un, yeah, that thought crossed my mind, but I remember when I thought garnet might be ruby.
That would make that a nice piece of emerald.
nevermind

Wait a minute even I know corundum makes Rubies and Sapphires it does not make Emeralds which are beryl. Beryl is lower/softer on the Hardness Scale and chromium is what causes its green color. Jus' Sayin'

Here are some pics of a few of the things I found during my recent excursion to South Dakota.

Long story here, feel free to skip to the pics. lol.

It was quite an experience. I blew a tire in a very remote area on the way back to my hotel from the ancient river bed that I was searching. I knew my tires were questionable and planned to change them out before the trip but ran out of time to the extent that I had to leave for SD a day later than planned. Anyway the stupid crank down spare tire release on my truck wouldn't release the tire. Luckily I had signal and was able to get a tow truck driver to help me with that. It was getting dark by the time that was resolved. Damn was I nervous driving through the remote wilderness area back to the hotel knowing I had no spare, the nearest tire shop was hours away and that I would not have signal for miles through that area. The next day we were to go out to an old mine's junk pile. That's the place I found the tourmaline and other things last year but I wasn't comfortable driving to the mine site without a spare (and crappy tires at that). So I made the decision to drive up to rapid city and get new tires which caused me to have to miss the trip to the mine, so I headed home from there a day early. Ah well, it's over now, I have 4 brand new tires and it was entirely my own fault. I knew I was going to be in really rough remote terrain on iffy tires. (Monty Python moment, "GET ON WITH IT!").

This is the ancient river bed we were searching. It is private land with permission to collect organized by a rock shop.

The main focus is fossils, while I spent most of time time looking for artifacts and nice rocks I did find some snail fossils including a pretty nice one.

This is just a piece with some calcite crystals.

I also found some prairie agate and chert specimens but I am giving them the mineral oil treatment right now so I don't have pics of those yet.

Here are the other rocks from my South Dakota adventure.

Some various cherts including moss agate, prairie agate, banded jasper also some quartz, calcite, and a piece of selenite. The prairie agate just right of the quarter is one of my favorites. I also really like the big moss agate on the right side of the container and the calcite in the lower left.

prairie agate
Looks like halite to me.
I've never heard that name for a specimen before, who gave it that tag?
That little red one down in the right corner looks cool.

Oh, I see, that is calcite, you said. I misread the whole post — sorry.
The agates are called "prairie agates" because of their location. <heh>

How old do you figure the snail fossil is?

The prairie agates also have a certain look to them. They tend to be less transparent than most agates and have wider, feathery banding patterns. The area we were in is also known for fairburn agates but so far I haven't found one that I would consider a fairburn. Like any other agate, prairie agates are predominantly chert/micro-crystalline quartz.

If I had to guess, 23 to 34 million years old (Oligocene period). That's a wild guess based on the age of other amphibious specimens found in the area.
