Only 70 kms from Arusha, Tanzanite One Mining is the largest and most sophisticated mine of the precious blue-violet gemstone, tanzanite, who, in association with The Tanzanite Experience, offer mine tours through their visitors centre, situated in Merelani. Discover the intriguing universe of tanzanite from mine to market, through a geological/mining presentation and, for the more adventurous, a tour into the mine’s first ever JW Shaft. Proceeds of funds generated from mine tour entrance fees and tanzanite sales will be used to support further community upliftment projects within the area.
