Is Arkansas the Top Diamond‑Producing State? No—It’s 4th in the U.S.

No. Arkansas ranks 4th in U.S. diamond production (mainly from the Crater of Diamonds State Park, the only public diamond mine). Globally, the largest diamond‑producing regions are:

1. Yakutia (Sakha Republic), Russia
2. Botswana
3. Canada

Arkansas’s output is significant for a public recreational site but tiny compared to industrial kimberlite pipe mines.
