An opalized shell ?

I bought a jar of rocks from a thrift store and found this fossil inside. It looks normal when dry but when it gets wet, more is revealed!

What would be the best process of cleaning and polishing in order to enhance it? A series of sandpaper grits? Or should I keep it in a jar of water and just leave it alone?

Help me ID this heavy baby!

Found this in the San Juan Islands when digging a new garden. It’s super heavy, very cold and impossible to break. We cut it with a diamond saw. The inside was so hard and had almost a granite like surface. It’s not magnetic as far as my fridge magnets are concerned. It’s leaves no mark when scratched on white tile. I brought it home because we have a lot of fossils here but it’s way too heavy like a big pile of iron. Any ideas? My friends think it could be a meteorite and don’t want me to continue to cut it open but I want to!!!!

Check Out My Great Lakes Epoxy Resin Decor - MI Fossils & Stones

https://ronnisrocks.etsy.com

I decided to create an Etsy page for my hand made coasters and rock decor. I collect all of the rocks & fossils myself along the shore lines of the Great Lakes in Michigan.

My real goal is to share my favorite parts of Michigan with people while also giving myself an excuse to take home “just one more rock” on my beach adventures.

Use the link above to check out my selection 💙

I am starting off small for now, but will be expanding soon - Stay tuned for more to come!
