This town is the center of emerald trading, the actual stones are mined a few kilometers away.
Proximal to the Shakiso mine, the host rock to the emerald pegmatite is dominantly talc schist with minor chlorite. The ultramafic rocks overlap the schist rich in mica and chlorite. It is inferred that ultrabasic rocks are the main rocks for the mineralization of emerald.

Other gemstones are also mined (Stephan et al., 2019).
