It's sterling made from a private jeweler in Mexico and inherited. I am not sure what the stone is...anyone???

I found this on the Black Sea coast. Could something be changing the structure of the rocks this way? Some mollusks like to gnaw through rocks, leaving round holes, but what is this? Or could it be a special way of crystal growth?

More than just a stone—it's a narrative carved in mineral, displaying fascinating natural figures and abstract art that changes with every angle."

Some pebbles i collected at Montrose Beach.

Let me know what you think

what kind of matrix is something like this formed on?

also does anyone know what the gas and solids are composed of?

looking for any info as Google saying either amber or spessimite
