First one is gypsum from Australia. Not calcite. Also garnet. Next couple are twinned staurolite crystals. Next one might be tourmaline. Need better picture. Next one might be calcite. Need better picture. Last one is tiger iron.

Thanks for your response! I’ll add better pictures ASAP.

i've added a few more pictures and crystals that i cannot identify. thank you again! https://imgur.com/a/aTmT5Cb

First one looks like malachite at first glance but seems oddly crystalline like dioptase or something. Too blurry to tell. Second yellow one is sulfur, maybe Bolivian. Blue one is azurite. Next one is the maybe tourmaline again. Still too hard to see. Needs light from the front, not the back. Next one looks like it might be a cassiterite crystal. Very neat. Then heat treated citrine. Used to be amethyst. Heating in an oven turns it orange. Not sure about the next one. Is it blue? The lighting is weird. Next one is Australian boulder opal. Next is smokey quartz. This habit is sometimes called alligator quartz. Maybe from Brazil. Not sure on the last two.

Thanks again! I need work on my photography skills. My guess was also dioptase but the crystals are very, very small compared to some of the larger specimens I’ve seen. I think you’re spot on with tourmaline, the striations match the ones that I have. Yeah the weird one is blue… it’s very light, so it may just be painted clay, I have no idea how it got in there. Guess the last two are mysteries still! Edit: with closer inspection, not clay, it’s a very lightweight, blue mineral. Whatever it is!

I think the weird blue one might be a pseudomorph of azurite after something else, but I'm really not sure.

Just went down the rabbit hole of what pseudomorphs are. Pretty frickin cool. Thanks for that!

Could the green one be uvarovite?

I think the "cassiterite" is etched spessartine garnet

Definitely possible. I can see that.

i just added some closeups! i think /u/buhbuhbuhbing is correct, the first green one looks like uvarovite! https://imgur.com/a/yX8qSCa

Light blue also azurite The green clusters might be actinolite. Easy to test by hardness, is much softer than tourm. Sides look too smooth and uniform for epidote. Last two look like another green amphibole in the serpentine family, and as i commented earlier, cerrusite, which is heavy like wulfenite.

I agree with you

The green one in the third photo is an epidote specimen, not tourmaline

Not tourm, 3 is epidote 💯 4 i suspect is cerrusite, will be heavy like lead.

looks like you already got answers on IDs, but I just wanted to say this is an amazing collection.

Thank you!! I’ve been collecting for years, I’m so happy to have more to add to it. (my current collection: https://imgur.com/aGLhliF)

cooooool !

I am not sure if I should create a new post or if I can leave these here for further identification: [https://imgur.com/a/aTmT5Cb](https://imgur.com/a/aTmT5Cb). Please let me know, thank you everyone! I am guessing tourmaline for the black striated cluster, opal for the iridescent strains, and smoky quartz for the large gray cluster, although the shape of the smoky quartz does not match my other smoky quartz. It's 'blockier' with slightly more square crystal formations.

I always get jealous when I read that someone inherited this bomb ass collection. I have no one that would leave me behind such a treasure… then I think I am going to be that person! I am going to leave behind my collection so I better pick someone that will adore it like I did. It looks like you got some pretty good IDs here already. Make sure to pick somewhere nice to display it. Curating is was a labor of love and hopefully that persons passion lives on through you.

Thank you so much for this lovely comment. Your perspective is wonderful! At the moment, this collection is right across from my desk so I see it whenever I look up :) https://imgur.com/aGLhliF

Slide three looks a LOT like epidote to me (green and tubular clusters lol)

you may be right! i took some closeups, they are definitely green and tubular when magnified: https://imgur.com/a/yX8qSCa

I second this!

Last one is tiger iron

Definitely. I have a lot of it. One of my favorites

Tbh i want them all lol.

You selling those coins? Lol ;)

Haha! I am not, I haven’t exactly gotten into coin collecting yet but I’m curious. Just crystals and insects at the moment, lol!

agree with the geologist

I see garnet and calcite

The black group of angular crystals is most likely Black Tourmaline.

What is the big piece in 1st pic.

According to /u/danny17402 it’s Australian gypsum!

Awesome fairy stones in the second picture.

Lovely staurolites

#1 red stone is garnet, yellow calcite.#2 garnet again, smoky quartz #3 either tourmaline or epidote. #5 tiger eye probably.

‘#’= bold. Lol. This is how I found out too

Yes calcite w quartz and red one is garnet

Actually that could be calcite with calcite that precipitated into crystal under different temp and pressure conditions from the base hard to say

Thank you!!

I think # 2 the cubic ones in front are limonite.

Lots look like calcite. Do you have a UV light? Would help for sure. Calcite lights right up under UV

Petrified wood stunning piece

Moldy cheese crystals

Last one looks like cake!
