Sources & method
How American stone is researched, what the records establish and where to check the evidence.
Coverage
Quarried currently lists 337 materials and 102 public company profiles, organized into 101 producer listings for browsing. Related companies can share one listing while their quarrying and fabrication roles remain separate. Material listings include natural expressions, selections and supplier ranges; they are not a count of distinct deposits.
Coverage is growing. No listed stones does not mean a state has no quarries. Producers do not pay to be listed, and inclusion does not require membership in an industry organization.
Browse 101 producer listingsHow we research a stone
Producer documentation, industry directories, technical reports and quarry records are compared to establish a material’s name, American origin and producer relationship. Source links and review dates let readers trace those findings.
Extraction country, state, quarry/operator and MSHA identity are checked separately. Evidence for one does not establish the others. A verified state can be shown without claiming a particular quarry or MSHA record.
Supplier-stated U.S. origin is labelled separately. A listing whose U.S. origin is unconfirmed stays public only during a dated, active review; it is removed from discovery if that review expires without supporting evidence.
What the evidence can tell you
A source-check date records a review of available information, not a quarry inspection or confirmation of stock. Active and Intermittent are regulatory classifications, not promises of present production or delivery dates. An MSHA mine ID identifies a regulatory record; it is not a quarrying permit.
Materials may remain listed when an associated MSHA record is marked Abandoned. The status, record date and confidence of the association are shown separately. Current marketing does not override MSHA status; current stock and the supplying quarry must be confirmed with the producer.
Photograph sources, credits and permission records are retained with the research. A source credit is not permission to reproduce an image. Representative photographs do not define the full range of a current order. Confirm origin, range, finish, dimensions and suitability with the producer before specifying, and request current physical samples.
Sources and research records
The research draws on producer documentation, the Natural Stone Institute catalogue and dated MSHA records. Individual records carry their source-check dates; regulatory snapshots are not real-time operating information. NSI catalogue coverage does not imply membership.
The expandable lists below include public listings and records retained for research or historical context. Their totals can be larger than the public catalogue because an archived record is not necessarily a current source of supply.
Detailed research notes and source evidenceCurator disclosure
Quarried’s curator operates Sylacauga Marble Quarry and has an ownership interest in it.
