Arusha: tanzanite buy lane for the Mererani mines

Where: East Africa & Indian Ocean · Africa · approx. -3.37, 36.68 (vicinity only)

Why this spot: Rockhounding locality: tanzanite exists only in a 7 x 2 km strip near the Mererani Hills; the mines are fenced licensed blocks, so Arusha's graded-dealer showrooms are the collector's lane

What turns up: cut tanzanite with grading certificates, tanzanite in matrix specimens at dealers, eyes-only: museum displays of rough and mining history

Access: Clean.

Buying certified stones in Arusha is legal and the only sane lane: the mining area is walled, permit-only and periodically closed to outsiders; export of rough over 1 gram is banned, so buy cut stones with certificates and receipts
