Three answers. In the right order.
From mystery object to useful context.
StoneScope is designed around the questions collectors actually ask: What is it? What might it be worth? Why?

Not a geology lecture.
A decision-ready result.
Identification is only the beginning. StoneScope surfaces the details that make the result useful — confidence, market context, comparable specimens and the visible reasons behind the estimate.
