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
Wikipedia documents the single-source deposit, government Blocks A-D and export rules; Tanzanite Experience confirms its Arusha museum-showroom on India Street
