Geological context

How the occurrence is understood

National Diamond production documented in the USGS 2026 summary.

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.

Current production

Diamond

Recent, date-bounded evidence documents active production. This status requires periodic review.

Current production verified

National production documented by USGS Mineral Commodity Summaries 2026; this does not verify every mine.

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.
