From where I’m sitting in my home office, there is an array of glacial boulders in the flower bed outside my window. I picked them from a farmer’s field (with permission) – a wide assortment and roundish. As a geophysicist, I only know three rocks, and all three are present: granite, not-granite, and maybe-granite.

I know big rocks, cool rocks, regular rocks
Closest to me, a granite or marble countertop that’s actually cool. My soon-to-be geologist friend was always pointing things out.
Oh, I forgot about that. I have granite in the bathroom. It is definitely granite. I know that one.

This is gold. Yoinked.
Presumably calcium oxalate
You should get those looked at ;)
Does my Orthoceras fossil pendant count as a rock?
Sure! Does it come with a story?
My wife caught me bashing gravel with a hammer one morning and asked what I was up to. I told her that I used to love digging for fossils and she took a note.
A few weeks later this showed up:
Not THIS one. But very similar :)
That’s a keeper! And the pendant is cool too ;)
A small beryl crystal I EDC, and a large specimen of silicified tuff from my claim that lives in my office.
silicified tuff from my claim
Oooh! What’s your claim? Anything cool?
The tuff was flow-banded, and the silica followed and preserved the structure. So not exactly agate, but there are sections that look much like it. Other minerals would be cooler, but it is nice lapidary stone!
Do you sell them raw, or just use them for your own purposes?
I am barely getting started with lapidary, like at choosing a saw right now. Eventually both, I hope (thus the claim).
Feel free to post project updates here. This isn’t !woodworking@lemmy.ca, so we won’t have anything like their traffic, but there’s probably quite a few rocks and minerals nerds here who would love to see updates! Myself included :)
For me, I have a monomineralic rock in my head made of apatite.
Some fluorine replacement going on in that mineral?
Maybe in elementary school… but I still have them so it likely worked. When I lived in town they started putting it in the drinking water so maybe that helped!
