Does this rock look like it has minerals in it

I don't think it's tourmaline, I think pyroxene, or even amphibole, would be more likely. To be sure, you can test the hardness against a quartz crystal. The tourmaline will scratch the qtz, the amp/px won't. Nice rock tho

It's hornblende. Just did a scratch test with quartz and material is coming off the sample. Damn I really though it was Tourmaline because of how large the crystals were

Flint is chert (which is quartz)

The mystery of the blue feldspar like mineral has been solved. It is in fact, a blue feldspar. More specifically it's Cleavelandite, a variant of Albite. Turns out it's fairly common where I live. Here are some small ones I found.

gemstones are generally not of cobble size, lol. every single gemstone mine on the planet is currently being operated. we mortals must make do with less-than-gemstone-quality material.

thats a great specimen, but im not sure any asbestiform is rare. actinolite was discovered circa- expansion of roman empire era. prove to me it's rare, describe it further.

To be included inside of clear terminated quartz like that is only really found in an area on the China-India border in the boonies basically
>>
>>2754066
eh. maybe. just dont pay too much for it. it's just asbestos. one of many. in fact, one of the top five, if memory serves. actinolite has been mined for literally thousands of years, along with all the other asbestos minerals.
>>
>>2754068
I don't pay anything beyond what it's worth and only at wholesale prices directly from people who get it from the mine or very close to it

You're dense(like a rock) for trying to value it based on it simply being actinolite and you know nothing of valuing gems or minerals, it's more valuable than everything else I posted and I could literally find you truck loads of emeralds, rubies, diamonds, garnets, and tourmaline etc but to find clear terminated quartz with nice bright green actinolite is something that you will only pull from a rare pocket and it is immediately bought by collectors and people who sell to collectors (me) or make jewelry

Yes it's not as rare as a GOOD Emerald or Ruby but that's beside the point, that shit goes for upwards of 10-15 a carat

most likely you can find this mine here https://www.mindat.org/loc-3585.html
gold is usually dispersed as micro inclusions in sulphides, most commonly in pyrite and arsenopyrite, it is possible do find native gold in some veins and it forms very small leafs and wires
>>2754003
weathered biotite also has this yellow color, distinguishing those two by eye is basically impossible, normally in gneiss or pegmatite i would suspect biotite, phlogopite require magnesium source so it occur rather in some contact zones in those

listen, man. i know your type. i've worked with you, i've seen you get excited over finding buried treasures in the wilderness. bluntly, i dont care about you posting photos of gems you purchased online, had shipped to your house, cleaned up, and photographed. you have nothing to prove to me, don't sweat it, you do you. take this lightly: gems and minerals are scams 99% of the time. sellers will craft the best stories you can imagine in order to make a sale. dont get me wrong, you have great specimens. but theyre just that. specimens. anyone can buy gemstones in current year, we all have the internet.

i have a ~30lb boulder of some local amphibole and quartz conglomerate. you c'mon over to my place, i'll cut it up, and you can make some asbestos jewelry for yourself and me. on the house.

Most of us don't purchase gemstones. Every rockhounder does, in fact, polish some of their finds. just not many, because frankly, lol why bother its not worth it. we're perfectly content placing a handful of rough gemstones in a 4oz soil jar, labeling it, and putting it on a shelf to be forgotten for a few years. sometimes, we get together, smoke the ganja, and do stupid shit. like pool some our junk finds together, have a bbq, cut a bunch into fun shapes n shit, and store in an old wooden treasure chest that's actually only like fifteen years old, but i made it kinda look weathered and beaten. then we give them out at halloween to kiddies because a few of us just stick with the whole pirate theme for halloween every year. treasure chest full of roughly-cut junk gemstones kids wont notice, some laffy taffy and skittles.

also, it would take a shitload more patience than i have to cut and polish shit like this. i wont do it, maybe a grandkid down the line might wanna cut it. if you have any pals who rockhound, i guaran-fuckin'-tee it that you can simply show interest in any one of their specimens lying around and just ask them if you can cut or polish it for yourself. we all keep shit like that lying around to "brag" about or seem cool to the kids my buddies brought over. you give a six year old some big chunk of colorful chert, and that kid will be curious for hours.

Why would I destroy the natural beauty of the mineral by polishing it?

>>2754286
to reveal natural beauty of the mineral by polishing it
while there is no point in polishing shit from that pic, cutting and polishing is only method to reveal textures of a rock or for example vein
having rock crack open with hammer isn't more natural than cutting it, ofc nobody is doing that with automorphic crystals other than for chemical analysis

You really don't know anything about the gem and mineral business and it's so bizarre how stupid you are sitting here trying to talk about anything, let me guess, you think diamonds are valuable?

Let's get one thing straight retard, basically all rocks are paperweights and even if you carve it into something cool it's probably still a paperweight. There's nothing inherently valuable about them in a modern society except from a collectors point, to put it into your stupid modern brain in a term you can understand basically real NFT's that earth generated a long time ago and we can make more of some of them but can't make more of all of them-but they won't be the same. There's two types of rock collecting and it basically boils down to specimens and worked stones. Specimens are as the name implies basically a good example of a rock/crystal from a local and often something rare. You could not replace them legitimately unless you get really lucky and they hit a pocket of it somewhere on the planet that's undiscovered (Keep in mind China is deep in Africa right now taking all the shit that's in one of the only places the world hasn't totally catalogued so the chances of hitting a pocket is low). Worked stones are things like carvings, jewelry, etc. This is where 99% of the scam industry comes in because if you don't have something legit you just cut it to make it look cool (cabachons, carvings) and if you don't have a legit crystal formation but you have clarity you can just cut it into a faceted stone and make fancy high class jewelry.

I go to the worlds' largest gem and mineral show every year and have been there for the last ten years working and collecting, what do you do? Take this picture and multiply it by a thousand, and you still won't have the slightest idea of how big the event is. Most people really don't understand how much raw material of 99% of the common shit you would see in a Jeweler Cabinet is, you're one of those people.
>>
>>2754225
yes congratulations you've found several kinds that aren't green and the two green ones you've managed to link were collected long ago, one in the 50s(california) and the other hard to say but the guy is just a collector from looking at his uploads you can see he collected a different unrelated quartz from the area and photographed it and detailed when he personally collected it but for the green actinolite in quartz he just mentions the locale with not even a little history. Probably bought that one from someone who took him there or told him about the spot and he went there looking himself. Your Switzerland one isn't even the one I was expecting, because there is plenty from Europe that is all mined out.

I need a supply of it yesterday for jewelry and specimens, linking me mindat specimens as if those are accurate representations of what you could possibly hope to get is hilarious. Half of those sources are exhausted, most of it was collected long ago.

You cannot fathom the scale, no pictures would do it justice you'd just be looking at tents or a big quartz crystal, maybe a case or a tent like in pic related. Most of the serious dealing goes on behind closed doors with things that nobody wants to bring out into the public's reach. Every single hotel along the highway in Tucson turns their bottom floor into a showcase where every single room is a different mine owner, different jewelry store owner, different jewelry maker, artist, collector, etc. That doesn't even touch the pop-up tent showcase space that goes up where people rent 30x70 tents etc to peddle their shit


I can show you a picture of a massive tent with a bunch of booths but that doesn't do anything justice

I think these are calcite, but I'm not sure. What kind of vinegar do I need to do the acid test? All I have is distilled white and that didn't react with my aragonite sample at all so I figured it's not acidic enough.
>>
>>2755283
10% at least, but vinegar reacts very poorly with big crystals, it's much better with fine crystalline rocks like limestone (because crystals react easiest on the edges)
better to buy hydrochloride acid online
it can be also dolomite, baryte or fluorite, or their mixture, no way to tell from samples like this

it's possible, sure. good grades of ANY product are moderately valuable lol, i agree. however, if we're gonna use $ as the metric in a dick measuring contest, good luck against my ~40lb chunk of chrysotile conglomerate. and all it cost me was a little bit of fuel and beef jerky. betcha my chunk of amphibole gets a higher price at auction than some polished 10c piece of jade lol.

i bet if i cut some cross-sections, i could get something similar to this. entirely different parent material composition though. but what are we talking about lol? this is /out/, we find rocks. /biz/ occasionally has a gemstone thread, but it usually dies out without much input.

yeah i mean, don't get me wrong. ive had an inspectors and supervisor/contractor license for years. amphiboles really are neat. it's just a shame we haven't figured out a reliable way to keep people from disturbing the shit, inhaling the fibers, living with quartz needles in their lungs for twenty years, then suddenly die.

once we figure that out, asbestos is gonna make a come-back.
>>
>>2755828
shit, im a little blazed. meant to also type a neat fact. in the ahera industry, there are three things that we are allowed to automatically assume are not potentially asbestos containing material: wood, glass, metal. asbestos has never been used in developing building materials constructed from wood, glass, metal.

however...a few rare exceptions exist. one notable example for asbestos in glass is spacecraft. glass viewing windows on spacecraft is constructed of some ultra high tech recipe involving the use of some asbestos, probably chrysotile but i dunno. i also recall hearing from an old dude some old dance or performance floor he once saw fibers embedded in. gut instinct correct, someone made a solid piece of glass flooring with asbestos tossed into the mix.

It's only bad if it's the fibrous stuff right?
>>
>>2755848
correct. the only reason asbestos is an issue is because of its fibrous structure. the actual literal physical and chemical properties are the perfect combination to be inhaled, get stuck in lungs, and never break down or go away because...it's quartz. it's non-reactive. scar tissue builds up over decades.
>>
>>2755852
Oh thank God. I though my fancy hornblende was dangerous for a moment there.
>>
>>2755856
for the life of me, i cannot recall the name of this light blue amphibole i found in boulder city nevada, just a short drive over. its well-rounded and weathered, likely bottom of the ocean like fiddy million years ago.

i've seen specimens of the same amphibole both as fibrous and as well weathered like an ocean pebble. ive got a specimen of the latter, perfectly safe. just dont fuckin crush it and snort it. geologists lick rocks frequently, so i think this warning is warranted.

>The researchers first found the fibrous blue and green amphibole mineral lining fractures in Miocene granitoid plutons in an area of the McCullough Range south of Las Vegas.

this is certainly what i'm trying to remember. i feel like i recall it being named something else though. but im sure im splitting hairs on memories from like fifteen or twenty years ago. geology field trip with metcalf out to boulder city, went to a few outcrops, picked up a couple light blue specimens. i actually tried finding it yesterday. it might be in my one singular box of mish-mashed rocks i like but have no clue where i got them. oh well, its not rare.

nah m8. minerals that meet the definition of asbestos are only ever dangerous to human health when they are fibrous (and also airborne). every asbestiform has fibrous and non-fibrous varieties available for you to find in the wild. doesnt have to be contained inside anything lol, read a book or go outside and look for yourself

I think they just pulled a picture off the web but the fact that several pieces are multi-colored and not from differential uptake suggests it's the real stuff. And yeah, it gets it's color from chysocolla and malachite. But at 100$ a carat for cut stones you better believe people are faking it.

>>2756810
it looks like rough Chrysocolla/malachite/azurite unless it's a piece of Gem Silica and then it is basically Chrysocolla with the hardness of Chalcedony. The reason it's valuable is because Chrysocolla, a bright blue, is often extremely delicate and cannot be polished without extreme stabilizing(glue) and even then it often doesn't work well. Gem silica is basically already stabilized in the Chalcedony. They search and search the piles of Chrysocolla for a tiny piece of Gem Silica

Hey, southern anons. My boyfriend and I are going on a week-long rockhounding trip, from up north so we’re hitting Kentucky for geodes and making our way down to Arkansas, going right to the Carolinas, and back up. Any notable spots to go and visit from all of these states? We do our own research, we have some spots picked out, but I’m always open to recommendation.

Kentucky specifically seems to be a little hard to find spots that aren’t on private property. Would love to hear your experiences traveling and rockhounding.
>>
>>2756871
90% of what you find outside on the ground will be Quartz, Jasper or Agate and often a bit of flaky Mica. Jasper and Agate are extremely similar, agate will often have more translucence or the ability for light to shine through it. Jasper is almost always 'shiny smooth with no translucence' and agate is almost always 'rough but translucent'. There are many different types of 'named' jasper that are all extremely unique looking and so you can easily tell that is that type of jasper - although you finding a particular kind of jasper in your back yard is extremely unlikely as they usually have specific pockets.

Certain types of jasper were really abundant back in the day and now they are becoming valuable because the sources have been exhausted. Other types have a trade name and that trade name is only applied to certain material that came out of specific mines (for marketing purposes) like the Tiffany Jasper out of Utah, which has gone through many phases of 'Oh this is all we're gunna get of Tiffany Jasper!!!' and then next year they find another 'pocket' right next to mine they were about to 'shut down'
>>
>>2756942
dont go rockhounding unless you already picked out a spot to travel to. you dont wanna be aimlessly wandering around a new site youre unfamiliar with in a different state. pick one site near a road youll be traveling on, then stop there for lunch and a walk.

if its geodes n shit, find a decent river near your travel route. eat lunch, kick rocks around the river sides, continue after finding some geodes.
>>
>>2756942
That is such a wide range you could spend the entire week at any single spot. Basically everything out east is private land and you'd be best creating an account on mindat and finding some obscure guy who owns property that would allow you to come rockhound for his Galena or some such bullshit.


I can sufficiently tell you that from my years of experience in the business, the locations on the eastern seaboard that people give a shit about the rocks found there are few and far between. You're looking at Herkimer New York for Herkimer Quartz, Southern Arkansas for diamonds, Mid-Arkansas or Southern Missouri for Quartz, and literally no-where else unless you're looking for really obscure non-flashy shit.

yup. here's a piece of southern nevada jasper with some iron. we dont really have any magnetite, but we do have iron scattered around occasionally. only piece i have with a big chunk of black iron. our jasper is pretty much only blood red. its got that real waxy feel.

planted it in my front yard. real good juxtaposition between light brown soil and green cacti.
>>
>>2756965
Some of those aren't even jaspers. Meant to mention unakite before since epidosite grades into it. It's altered granite. Rainforest jasper is a rhyolite. Bumblebee jasper is a travertine.
>>
>>2756968
>>2756967
We're cool with finding any rocks, including less flashy ones. We also know we could spend an entire week at just one site, but we don't have too long, and we're covering a lot of ground (so many states we have never been to). We spent last year in North Carolina and went to some big sites over there (emeralds and beryl at the mica mine). The mica mine was actually super cool, I want to go back there because we didn't smash open the rocks like we should have to find more.

We're going late August, so I know we're in for some shit weather wise, but we're doing the planning now. Have some spots picked out like I said, just trying to find perspective from people down there.

Funny you mention Galena because we have some from up here already. Really have to stop digging in lead soil though.

Also hoping to find some fossils or teeth.

I will have to ask him what sites he has picked out already.

Completely separate note (only slightly related to artifacts)- was there a big Native American presence down there? I know up here there was, I know in the west there is, but I've never heard or read about it down south. Just interested, maybe I can find a quartz arrowhead.

Another separate note, I reccomend going to the Great Lakes for rockhounding. So much fun! Found an ammonite and had a blast.

i'm all for taking whatever i find, just be aware about fossils. you can grab all the invertebrate fossils you want. feds get involved if someone catches a person selling a vertebrate fossil.

the blue in quartz is caused by the tindall effect, the same thing that causes the blue in the sky

reason i ask about layers, is because if it looks like it has a laye ror shell, id guess a geode. also do an acid test, quartzite shouldnt react right?
