Can Someone tell me what kind of stone is this?

[shkoumed]

I found this stone or rock or whatever I don't know what to call it, but I don't know what it is, can someone professional tell me what kind of stone is this and is it valuable or not?

Welcome!

Trouble with asking a professional is that you have to pay them.

My free opinion is that it is mica.

well I looked it up on google and I think you're probably right, it looks like mica, but how much should I pay to get someone professional? and where would I find someone professional?

You could send a picture to a geologist at a local college. I have sent pics of artifacts to local archaeologists and they are always more than willing to help me out.

Looks like it may have come from a normal mountain in southern florida. Thats just a guess.

Approximately 50 years ago my hobbies were rockhounding (hunting for minerals) and cave exploring. Sometimes the two got combined, when I encountered various interesting minerals inside a cave. I clearly remember seeing a large broken piece of Calcite. Your mystery-rock appears to have the same cleavage and fracture-pattern as the Calcite specimen I found in that cave. By the way, Calcite's color can vary, from almost like glass to honey (including dark honey) according to how much dissolved iron got mixed in when the Calcite crystals were forming.

Do you think your mystery-rock is "native" to the place you found it, or was it possibly carried there (such as, by a gravel- or stone-delivery truck). I'm asking because it's important to know what the Geology of your part of your state is. Calcite forms when Sedimentary rocks were deposited by ancient oceans... not created by fire (Igneous/Volcanic rocks), nor heat/pressure (Metamorphic rocks). For example, the mineral Obsidian (volcanic glass) is not naturally found in Florida, but people have actually found some pieces of Obsidian there because I arrived in a load of gravel.

I disagree about it being mica. Have you cleaned it at all? Water and a soft toothbrush alone, a little mind hand soap, too. It is interesting! There is one "rock" I don't know much about as I don't think we have any in my state, but it COULD be something like petrified wood. Otherwise, there are many minerals that grow in that type of pattern.
