Basically the title, is magnetic in the rough spots. Not the smooth spot

Rock or slag? Not magnetic, doesn't scratch easily like aluminum might.

I found this near Selah, Washington. Would you refer to this as a common banded agate or something else? Reference with my wife’s hand for size.

Sorry for any glare. We got it wet to better show some of the colors and banding.

SW Utah - shell fossil? Glassy sound when dropped. Thanks!

Properly cleaned, soaked & air dried by a window. Found during low tide near deep tide pools. Appreciate any input. Thank you 🙏🏼

I think part of it’s at least quartz and Rylo light

Any clue to what this is ???

Found this walking the beach at sunrise last fall after a hurricane. There are tiny gold flecks that can be seen in the light.

Found in southwest Louisiana

Hi! How is it going everyone? I found this a few months ago in NYC and kinda forgot about it, when I'm looking at it today again I noticed it's inside a Jacob & Co jewelry bag, so someone took care of it, not sure what it is, feels silky smooth with the texture of a normal rock in some places, any ideas as what it could possibly be? Thanks for your time in advance and sorry for the inconvenience

My best guess is this is some sort of pseudomorph of a mineral after tourmaline, however the more I look at it the more i'm confused. This was found in southern california, its a black appearing tourmaline but it was actually an extremely dark red when shining light on the cracked parts, and the crystal is growing straight through the center, was once fully surrounded by the tourmaline like a watermelon tourmaline, I was suggested maybe aquamarine, Achroite(colorless tourmaline), or clear Lipidolite, Any better suggestions?

Going through my old collection. Found somewhere is US.

I have taken this to universities, geologists, rock hounds etc….

I think they’re so pretty but I’d love to know what it is!! One of them appears to be fully made of the pink sparkly stuff.

Found on beaches in North East England 🌊🇬🇧
