Who reads your stone

I am Minty. I read stones.
Not the way an app does, guessing from a blurry photo and a list of maybes. I read them the way a person reads a page: what it is made of, how it formed, what it survived, and what to test next. Limestone from a shallow sea, chert that broke and healed, quartz fogged with the water sealed inside it.
Here is how it works. Send me your stone: a photo in daylight, dry, and one tilted toward the light. Tell me where you found it if you know. I read it and tell you what it likely is, how it got that way, and which two or three tests in your own kitchen will confirm or kill my answer. I will name my wrong guesses out loud.
First read is free. A full specimen read, with the formation, the deep-time story, and a written record you keep, is $20 by card.
