Arusha, a bustling city in northern Tanzania, is renowned not just for its proximity to the Serengeti and Mount Kilimanjaro but also for its rich deposits of gemstones. Among these, Tanzanite stands out as a rare and captivating gemstone, known for its striking blue-violet hues. This article delves into the story of Tanzanite, from its discovery to its journey to becoming a sought-after gem in the global market.
Tanzanite was discovered in 1967 by a Maasai tribesman named Ali Juuyawatu in the Mererani Hills near Arusha. The gemstone was initially mistaken for sapphire due to its vibrant blue color. However, further examination revealed it to be a previously unknown variety of the mineral zoisite. The gemstone was later named “Tanzanite” by Tiffany & Co. after Tanzania, its country of origin.
Tanzanite mining takes place in the Mererani Hills, the only known source of this gemstone. The mining process involves both artisanal and large-scale operations. Miners extract Tanzanite from deep underground using a combination of manual labor and machinery. The rough stones are then sorted and graded based on their quality, color, and clarity.
Ethical and sustainable mining practices are increasingly being adopted in the region to minimize environmental impact and ensure fair labor conditions. Organizations and companies are working with local communities to promote responsible mining, improve safety standards, and support economic development.
Tanzanite’s unique blue-violet color sets it apart from other gemstones. The gem’s color can range from a deep, saturated blue to a lighter lavender, depending on the angle of the light and the stone’s orientation. This pleochroism makes Tanzanite a fascinating and dynamic gemstone, prized by collectors and jewelers alike.
Compared to other gemstones like sapphire and emerald, Tanzanite is relatively soft, with a Mohs hardness rating of 6.5 to 7. This means it requires careful handling and proper setting in jewelry to avoid damage. Despite this, its captivating color and rarity make Tanzanite a highly valued gemstone in the market.
