Where geology concentrated the stones.
Gem deposits cluster in particular settings: pegmatite provinces, marble belts, basalt fields and the gravels eroded from them.
A deposit is local. The knowledge needed to understand it is global.
Comparing a new occurrence with well-understood deposits elsewhere — their host rocks, their gem chemistry, their mining history — is one of the most useful tools in evaluating an opportunity.
