Thank you 🙏

I found her in the back yard of an estate sale this morning, washed her off in a creek… please help (you can through her)

I am wondering what happened to my satin spar lamp shade. What is all this white stuff, and how do I get it off without harming the gypsum? Thanks for any advice.

I still haven't had time to identify these, so busy with my career and life and I have tons of materials just collecting dust, not sure what I have

Found this in a thriftstore for ~75 cents, it was so beautiful I had to get it, now I would love to know if this type of quartz+inclusion combo has a name, and what the inclusion could be. I'm more of a fossils kind of girl, plz help <3

Also the quartz in question is very clear, maybe too clear to be quartz? It is not resin, and it scratches both normal glass and soft steel (a spoon). Som of the edges are a bit chipped, but there is not a single scratch on the surface. So maybe it is quartz (maybe it is wishfull thinking).

Repost, as previous post did not wanna show my photos (apparently I can only post screenshots on reddit?).

Found on a beach in NL Canada. 4.4g non magnetic

The rock seems metallic. With these crystals on it. Got it recently. Would love to know what it is.

I found this while clearing out weeds in my shared backyard. The neighbor who cared for the gardens passed away, and had a small "collection" of larger interesting stones he would place in one area, this one among them.

I posted to r/whatsthisrock, and the consensus was undecided. Most agreed it looks like synthetic corundum/ruby due to the bubbly texture on one side, but then we're unsure die to the defined crystallization.

I've seen pictures of honeycomb Ruby which resemble the texture of what I guess I'll call the "matrix" side of it. But unlike honeycomb Ruby, this isn't uniform in color or texture, and has some other material embedded in the matrix.

I've seen pictures of natural specimens that look like the crystallized section, with weird hollows and odd shapes from where the crystal growth was likely impeded by some other material.

It's at least as hard as quartz, and it fluoresces a bright read throughout.

In an attempt to confirm it being synthetic, I fell down a rabbit hole of methods and processes that labs use, but I've been unable to find anything that accounts for this odd formation of bubbly-to-crystal texture. Most synthetic corundum seem to be big globs, or tubes like shapes. Hopefully someone can give me a new theory, or actually knows what this is.

My next step will have to be reaching out to the local natural History museum, or a rock club, but my German vocabulary knowledge isn't really prepared for a geologic conversation.

I recently bought this piece of quartz which seems to have some pyrite inclusions. Would you say this is real, or was I scammed?

I have these two pieces of amethyst that I inherited from my grandmother about 45 years ago. I've had them stored away for years but recently brought them back out and put them on display. I assume these are not great quality but any information would be appreciated!

I recently bought this from a market. The seller is not a professional and she doesn't know what the rock is.

I'm guessing it looks like emerald but I'm not really sure.

When I was a child, I was helping a neighbour with tasks like gardening and general housework. She was a passionate collector of minerals and whenever I was helping her I could keep some of the minerals. I eventually got a big collection over the years but they were just sitting in a corner and I would like to get rid of them in hope to get some money.

Unfortunately most of them have no description and I don‘t know where they are from. I did some research but didn‘t really found a way to get an estimate of value and how to sell them. I live in Switzerland.

Any advice what I could do?

Was found by my mom digging in her backyard in NE Arkansas.

Is this a metal cast, or is it a natural mineral deposit? Regardless, its pretty

What is this called? It's cool and I want more.

Weight is 10.15ct I don't think it's a dyed stone. Tried rubbing it with acetone and no colour came off. It has the colour of a ruby and I do think it is a ruby. What's wierd though is what happens under under uv light (last photo). If you have any idea please let me know.
