#Rock Collecting

[reddpenn]

Now that I'm back from the gem and mineral show, here are all the Cool Rocks I came home with!

A cute little coral fossil! He looks like a cauliflower.

A Keokuk geode! These geode beds aren't far from where I live, and it's always fun to have local specimens.

Phosphosiderite! This purple stone comes from Chile. It's so soft that it has to be stabilized with resin before it's cut. This one is a cross section of a botryoidial formation!

Speaking of botryoidial, this Hematite! Botryoidial means it has a bubbly shape kind of like a bunch of grapes. The faces of the bubbles on this pieces are super shiny and metallic.

Dendritic chalcedony, from Turkey! It's a white chalcedony full of dendrites - branching formations of manganese that look kind of like trees!

A cabochon for my cab collection! This one is made from a material sometimes called "ajooba jasper." The pattern is actually a cross section of a bunch of colorfully jasperized bivalve fossils!

Speaking of jasper, this one is Blue Mountain jasper, from Oregon! The circles in this stone are what’s known as an “egg pattern,” and jaspers which have them (Blue Mountain, Imperial jasper, and a few others) are collectively known as “fine jaspers,” the most valuable jaspers in the world.

Hyalite opal! This stuff forms water-clear spheres that look like jelly.

It fluoresces bright green under UV light!

Now to show off this year's haul of awesome agates!

Dryhead agate, from the Bighorn Mountains in Montana! This agate is named after the many bison skulls found in the area. A weird shaped guy with awesome red and orange bands.

Bou Lili agate, from Morocco! I like the name of this one. Soft banding and very subtle, muted colors. I've heard that this locale can produce peachy colors too.

Bear Canyon agate, from the Pryor Mountains in Montana! Agates from this locale have very stark black and white banding.

Red Fox agate, from Argentina! Sometimes this material is also called "crater agate" because the area it comes from is near the crater of an ancient volcano.

A Blue Sky thunderegg, from New Mexico! Thundereggs from this locale often have this two pointed, saucer-like shape.

It fluoresces really brightly!

Dulcote agate, from England! The bands of this agate are full of calcite, which gives them a strange, distinct texture.

Malawi agate, from Malawi! See all the cracks in it? Almost all Malawi agates have them. Frequent earthquakes due to the East African Rift cause these agates to crack and fracture.

Paint Rock agate, from Paint Rock Valley in Alabama! This agate is very rarely banded, and usually just contains swirls of red and yellow color.

A big, unpolished slab of Montana agate! This agate is known for its clear banding and black lines and spots, which are caused by manganese dendrites.

It's best viewed with some light behind it!

A smaller piece with really amazing dendrites!

Here it is backlit!

Fighting Blood agate, from Hebei Provence in China! This locale is known for its super saturated reds and yellows. This piece has purple amethyst crystals growing inside! They didn't photograph well; they are much more purple in person.

A really weird Fighting Blood agate! This one lacks the bright colors typical of this locale, but makes up for it with that super cool spiderweb pattern!

And finally, as is tradition, I came home with some Ethiopian opals! Here are the five I got this year.

And that's everything I got at the show!

This is your sign to learn more about 🪨 cool rocks 🪨. Become a certified rockhound now.

I have something so important to tell you: Last week my sister and I smashed a bunch of rocks in half. It released something primal within us, and I am compelled to preach the one universal truth I now know; The key to life is to recognize you’re a certified Rockhound. A Granite Groupie. A real Basalt Head. 

Some rocks are almost made for throwing. A life like yours demands more exploring. Go on, my little #rockhound. Find a rock to smash open. The best part about your new hobby? In the absolute worst-case scenario, the rock is simply filled with more rock. What a beautiful thing.

Remus has an inexplicable collection of rocks—oddly shaped ones, smooth ones, and some that are almost glowing. He’s been collecting them since childhood, but no one knows why. They just seem to soothe him when he's anxious. Sirius discovers his collection during a late-night conversation and, in his usual dramatic fashion, decides to start his own “rock collection” as a way to bond with Remus. He picks up rocks from all over the place and even “gifts” Remus the ugliest ones in his pockets, making them laugh together.

Sliced ammonites in resin.

Ammonites are an extinct marine invertebrate that lived in the Paleozoic and #Mesozoic Eras, about 408 to 65 million years ago. ammonites were cephalopods, a group of predators that also includes, octopuses, squids, cuttlefish, and nautiluses.

Cool rock time! :D These are from a parking lot on the way to the public library :3 It was also nice and rainy, so it was easy to see the patterns and colours better.

The wispy, veiny-looking one is my favourite, because it has a mark that looks like a little heart on it <3

Silly Tears of the Kingdom video where a speed runner got a comment about “You finished the game too fast, now what are you going to do? Collect rocks?”

Speed runner said, sure, let’s collect all the types of rocks in the game. A spreadsheet makes an appearance.

Ok tumblr, I need help identifying these rock/minerals.

I got these from the “world’s greatest rock tumbler refill pack” from national geographic, if that helps. The ID guide from the pack is sparse and vague so it wasn’t much help.

I used google image search to id these as best I could. Thanks in advance to anyone who helps!

Every single time I go into a rock shop or an antique store or a junk shop or any other miscellaneous shop that happens to have rocks, I come home with a cool piece of jasper. It has become a meme among my friends that if I touch a rock it's probably jasper. It is correct disturbingly frequently. Anyway my favorite piece is a heart-shaped piece of desert jasper that has the most gorgeous blues and oranges in it. Do you have a favorite piece of jasper?

I have recently decided to try and collect as many of the "fine jaspers" as possible, the ones that make "egg" formations. So those are my favorites currently! So far I have collected two.

Here is imperial jasper:

And here is blue mountain jasper:

I think the egg patterns in these are super neat. Here, I have drawn a little diagram explaining why they look like that!

do you still collect human bones and hair as much now?

With the explosion having caused most of the humans to be mostly vapourized to skeletons that are frozen to the ground, as well as the permafrost, all the good stuff is hard to get at.

I HAVE raided a mausoleum, mostly for hair and trinkets, not so much for bones anymore, I collect pretty rocks though sometimes!

I love sparkly rocks, there was so much less of them back on earth around the manor, but in space, any really small asteroids will have TONS of pretty gems if I just break it apart, especially my birthstone, which is peridot!

Spectrolite, a type of labradorite found only Finland

[penguinonfire]

Meet, Exogyra Ponderosa. It's an oyster fossil from the jurassic and cretaceous period. It's also known as a devils toenail. I use to find these at my grandma's house as a child. That's where this one came from ❤️
