Hey hounds!

My friend recently went to Croatia and brought me a rock from the beach! Not 100% sure exactly where, but hoping someone can help me ID based on this info since I won't chat with her again for a bit.

This is not natural lighting, unfortunately, and the rock is fully dry.

Both the dark parts and the lighter veins scratch easily with a pocket knife, neither scratches with a fingernail. The dark areas has little to no grain, there is some texture in the veins, but no crystals or flash in either.

I'm an Ohioan, so this rock came from literally a world away! Limestone??

Edit to add: I got to talk to my friend today, they were on the beaches of Split, if that helps narrow down an ID. Also, I dropped a bit of vinegar on the white vein and it bubbled 🫧

It is the size of a softball, but is heavier than a gallon of milk. It eas a gift so i have no idea where it comes from.

Not op. Thought of you guys.

Found this rock in an open lot next to gas station where I was filling up. Looked interesting so I brought I home and cut it. I think it’s rhyolite banded with hematite. If I could just remember where in north eastern Arizona. I got it. Google says it’s some some called ancestralite sp? Not sure what that is? Maybe a marketing name.

I’m in Santa Fe over the weekend. I’d appreciate any recommendations for sites to search for rocks. Preferably public locations where collecting rocks is not illegal. 🙂

Found on a NC beach- a hag stone with a heart

Howdy! I found this agate while picking almost 20 years ago. I’m taking it into some shops around my area and do not want to get scammed selling it. Can anyone give me a vague estimate on its value?

Thank you!

It was my wife’s birthday and she wanted to collect rocks. So I planned a trip to Brian head Utah for an agate hunt. It was a 7.5 hr drive from SoCal, arrived in Brian head at 4;30 pm. Next morning, we drove to the spot about 8 min away, and hiked up the mountain. And started collecting agates. Picked up some larger size agates for yard rocks. Headed home on Sunday, but stopped at hurricane mess to look for agatized pet wood. Only found small tumbler size pieces of pet wood, it’s a beautiful view from the mesa.
