The material is attributed to this producer; its quarry origin or operating relationship has not been confirmed.
Gramazini's exact product page establishes Virginia origin and diabase type; its company page generally states that it owns more than 30 quarries. Reviewed official pages do not expressly assign this named material to its own Virginia operation. A March 2024 newspaper report supports a Virginia quarry acquisition, but the own-quarry rule is left excluded pending a retained primary material-to-operator statement.
