Multiple Brazilian schist-hosted Emerald deposits contribute to laboratory reference collections.

Bidirectional relationships

Documented gemstones

Occurrence and production are separate claims. A production label is date-bounded and does not guarantee quality, origin determination, or market value.

Documented occurrence

Emerald

Authoritative evidence documents this gem at the location; this does not by itself imply commercial production.

Production not assessed

Occurrence is documented, but production status has not been assessed.

Sources & verification

Sources are deduplicated across the geographic record. Current-production claims receive explicit review dates; a map point never substitutes for geological or production evidence.
