Why this spot: Rockhounding locality: Ratanakiri means 'gem mountain'; its Bokeo area yields the world's best-known blue zircon, dug by hand from pits and tunnels and heat-treated to color

What turns up: rough and cut zircon (brown, becoming blue on heating), small amethyst and peridot in local trade

Access: Gray area.

Pits are informal artisanal claims, not a tourist operation: visit only with a Banlung guide who knows the diggers, and buy stones in Banlung shops as the clean lane
