These types of huge perfect specimens always take my breath away when I am able to see them in person. To think that this kind of stuff just kinda exists buried in the earth...

I am a part of a local mineral club which hosts several "field trips" a year to various mineralogically interesting locations (most of which aren't accessible as an individual, like private land and special digs at active mining/quarrying sites on their days off). I have never found anything even remotely as beautiful as the specimens shown, but the small collection of mildly interesting things that I've smashed out of the earth with my own 2 hands is amazingly satisfying to me. You don't even have to be a super dedicated "rock nerd" to take part, I highly recommend looking for local mineral clubs to join if this even remotely interests you. It's really a ton of fun!

That’s what really sucks about rockhounding as a hobby. In the US we have a blessing of public BLM lands where we can collect, especially in the West, but most of the interesting specimens in museums and fancy collections come from mines or some unique geological occurrence on private land. Getting them requires dropping lots of money or getting into commercial mining. The best most of us can really hope for is some small piece from tailings.

There are a few species you can sometimes find in washes when they get buried during massive floods, but other than that most museum quality specimens are impossible to find for rockhounds.

I still bring my trusty Estwing rock hammer everywhere but it kind of takes the wind out of the treasure hunting aspect.

Well, that's kinda how it has to be, right? If art museums displayed the artwork anyone can paint, they wouldn't be interesting to most people. Most museums are about displaying the stuff you otherwise wouldn't be able to find, buy, or make. It's still fun to learn to paint, even if you're no Rembrandt.

To be fair, there are some museums that go for depth instead of scarcity and I personally find them more interesting. The Computer History Museum does this pretty well. They have some truly unique items, but also plenty of stuff you can buy on eBay, just presented and explained well.

It's very common for art museums in Japan to have a room dedicated to paintings from local residents. As one would expect, the quality ranges from "why would you show this to anyone" to "can't believe how amazing this is". I always enjoy going through them.

I live in the northeast USA, there are very few public collecting spots around me. It makes me really sad listening to people who have been in the hobby for a long time talk about all the amazing collecting sites they used to frequent before they were paved over with parking lots or condominiums and whatnot. There isn't a whole lot of "wild open space" left around here to poke about in. Another big factor for keeping the public out of collecting sites that do still exist is that some people can't be bothered to be respectful in their collecting.

The Loudville lead mine in Easthampton MA, which used to be open for public collecting, recently closed due to irresponsible collecting and severe erosion. They closed off the entire recreational trail system, which has far reaching affects far beyond the rockhounding community.

I'd collected once at Loudville shortly before it closed and found a couple scraps of Pyromorphite, some tiny Wulfenite you need a microscope to see, and some Malachite. I am sad that I can't go back, now.

I don't expect, or really even want to find museum-quality specimens, I just want the ability to explore the minerology of my home region on a physical and personal level.

Just this past weekend I pulled a plate full of rare tellurides out of Otto Mountain for a Caltech PhD. You have to be very observant to find a good spot to acquire minerals out of the ground, but excellent large specimens are still out there to be pulled.

It isn't that difficult to find excellent mineral specimens, some boulder-sized, on National Forest and BLM land in the mountain West. There are many places where people have never been or where a fantastic-looking mineral deposit was ignored because they were too small (common with e.g. copper minerals).

Most of the ones I've found were incidentally discovered while hiking around off-trail in the boonies. I do always bring my Estwing with me just in case though.

Finding specimens is not that hard or inaccessible if you are determined. Virtually any place on earth has its own geomorphology history. Start by looking at geological maps to learn what kind of rocks/minerals you can find in your surroundings and look for old/active mines, quarries or any activity that excavates soil, etc. Specimens can be found sometimes in land deposits from these activites.
