The Discovery of Tanzanite: A Modern Gemstone Story
Tanzanite was discovered in 1967 near Mount Kilimanjaro in northern Tanzania by a local Maasai herder. The striking blue-violet crystals were soon identified as a new variety of zoisite. Recognizing its rarity, Tiffany & Co. introduced the gem to the world and named it “tanzanite” after its country of origin. This discovery marked the beginning of one of the most fascinating stories in modern gemology.
Tanzanite vs. Sapphire: What’s the Difference?
While both gemstones share captivating blue tones, tanzanite and sapphire differ in origin, structure, and rarity. Tanzanite, a variety of zoisite, is found only in Tanzania, while sapphire, made of corundum, is sourced from multiple regions worldwide. Tanzanite displays pleochroism, showing blue, violet, and burgundy hues under changing light, whereas sapphire maintains a consistent blue. Sapphire is harder and ideal for daily wear, while tanzanite’s unique color play and exclusivity make it highly collectible. Both stand out in fine jewellery — one for durability, the other for rarity and brilliance.
