Kintsugi-ed a selenite dish… what can I use to clean off excess epoxy?

Hello, I bought a 1cm aragotine on a fossils and minerals fair , and I have searched on internet that aragotine glows under uv light but the one I bought doesn't glow. Is it just some aragonites that glow or it's probably fake?

Question about my Aragonite 

Chromite from Iran 

Every now and then when the river dries up the black rock/mineral shows up, could it be coal?

Could these be coal deposits?

Need help identifying soft mineral. 

Hi everyone, i come to you because i am about to start an intership in january and one of my main task is to do petrology on thin sections cut inside metamorphised limestone (marble) and it is a kind of rock that i am not familiar with, i was looking for a book to have a reference and help identify minerals, if you have suggestions i'd be taking them happily

Thank you in adavnce

Hello everyone! 

I'm sharing my little find with you, a fluorite that I picked up myself in the Auvergne-Rhône-Alpes region.

I hope you like it!

Two different minerals would like help with 

Tektite but from what origin?

Rutilated Quartz (Rutile inclusions in Quartz)!

Extremely densely packed Rutilated Quartz (Rutile fibres included in Quartz)!

This was found in Southern California, Banning. I’ve never seen anything like it.  How was this formed? In the rock producing crystals or surroundings? The little pockets hold crystals. There are empty pockets wondering if those crystals fell out. Also wondering if I cut it will the inside be mostly chalcedony? The look to be going deep inside of the rock all the crystals. I’ll post a link to a video I took too and posted on Imgur since I couldn’t upload video directly with post.

Apparently this is basalt and chalcedony. How was it all formed? 

I won these in a raffle - cool juxtaposition of natural and manmade (bismuth). Any thoughts on what’s inside the geode?

my first rock and mineral show

Is this cinnabar in common opal?

My first Sampleite video on Reddit! Look at that powerful reflection of light!

I was (somewhat accidentally) gifted this specimen in early February in Tucson, AZ at Gem&Jam festival by one of the vendors. This festival happens during the famous Tucson Gem Show each year. He told me to come pick a free stone out of one of his “give away” boxes with the less valuable stones that they would give out for free to entice people to come to their booth. 

I dug around for a minute and nothing felt like it spoke to me until I found this one. I had never seen anything like it, and I’m usually pretty good at identifying the more common stones/minerals. I told him “I want this one!” and he immediately dropped his smile and said “Uh-oh, they’re gonna be mad at me for giving you this. I had no idea it was in this box. Do you have any idea what you just picked?” I said “No, but I’d love to know!” He told me the darker cola-colored formations were called Axinite and that one of his friends actually mined it from the only Axinite deposit in the United States and that it’s mostly only found on the other side of the world in Russia. 

He said that this was a very valuable and rare mineral and basically acted like I hit the jackpot in a box of crappy free stuff. I can’t remember super clearly since it’s been almost a year now, but I think he said the greenish clear stones in it are either Epidote or Prehnite. 

What I want to know is—does anyone have more information on the ID or value of this? I definitely don’t plan on selling it since I have a lot of love for this piece and the way it found me, but I would love to be better educated on it since it’s special to me!

P.S. I have fairly small hands for size reference and some of these pics are in .5x zoom so my fingers look strangely sized at this angle.

Axinite Valuation

<div class="md"><p>Thanks in advance</p>

Thinking of buying this golden ring, seller says that there is a sapphire and 2x small diamonds. is it REAL or no DEAL. The gold stamps are there tho.

I found this out in my yard and thought it looked really cool! Unfortunately I had no clue how to figure out what this is… until now, people of Reddit I hope I’ve come to the right place. Ps I’m in central Florida if that helps any.

Interesting rock or fossil?

I don't see this discussed- why are there two forms of Desert Rose? Are there more? Is one rarer than the other? What's the difference and is it okay to call both of them Desert Rose (even if it is somewhat of a trade name)?

Is this Stellerite or some other mineral?

<div class="md"><p>Could you tell me what material it is?</p>

Identification 

I know that this is majorly chrysocolla and that this is a prismatic quartz form … but, how did this happen?

As far as I understand, quartz can’t pseudomorph into chrysocolla, but that’s what it looks like to me. Or has this chrysocolla crystallised in the shape of a quartz point while filling in the spaces between other quartz points — kind of like a negative-crystal “filling”?

If anyone has any idea of what had to happen here for this to emerge, please let me know!

What happened here?

<div class="md"><p>Last pic: pinky for scale</p>

Got this tiny thing as part of a free gift in addition to an agate I bought. Any clues?

Can someone help me ID this? Was handed down but not sure what gemstone it is. Thanks in advance!

Gemstone ID?

Both the rough and polished are from the same mineral claim here in BC, Canada

Moss agates are one of my favorite stones, this is one of my best specimens. I’d love too see everyone’s favorite mossy ones look like

I’m finally starting a mineral collection sorted by minerals found in each state, does anyone know a good place to source stones And gems from?
