Hainan: Tunchang Yanggeling crystal mine site

ROCKHOUNDING RESTRICTED DOCUMENTED

Where: China Inland · Asia · approx. 19.33, 110.1 (vicinity only)

Why this spot: Crystal locality: China's first and once largest natural rock-crystal mine (the 701 mine), now a flooded pit and geoheritage site

What turns up: rock crystal and smoky quartz from local shops, historic 701-mine specimens, none to self-collect on site

Access: Restricted.

Provincial cultural-heritage site since March 2025, no collecting at the pit; visiting the Tianchi crater lake and buying Tunchang crystal locally are the legitimate lanes, with a geology theme park and crystal DIY planned
