So ive found this rock 13 years ago. It has grey rock like around it. And on that grey is orange on the edges of this what looks like crystals orange and white. Then the crystals are a light almost see through. My camera on my phone doesnt work as well. There was a bubble of clay around it and i took it off. This was inside amd i washed it off this is what it looked like afterwards

The pics are a little blurry, but, I am pretty sure I see a fossilized coral on the bottom right of the first pic, if that is the case you most likely have a vug of "dog tooth" calcite crystals. A little bit of vinegar (like a drop, you don't want to ruin them) should make bubbles.
