gem mining
A site where precious or rare stones are extracted from the ground by surface collection, digging, or blasting.
A gem mine is a site where precious or rare stones are harvested from the ground, either through surface picking, digging, or blasting.
The stones are recovered from a natural deposit. Surface collection can be sufficient; a tunnel or deep excavation is not required.
Cutting or selling gemstones recovered elsewhere is distinct from extracting them. A mineral mine has a broader mineral-extraction purpose with gemstone mining expressly separated.
