Tanzanite Gemstone Description
Tanzanite is a rare and captivating gemstone known for its mesmerizing blue-violet hue. Discovered only in 1967, it is found exclusively in a small mining area near Mount Kilimanjaro in northern Tanzania—making it one of the most geographically limited gemstones in the world.
Belonging to the zoisite mineral family, tanzanite owes its unique coloration to the presence of vanadium. It is typically heat-treated to bring out its vivid indigo-blue tones, often shifting between blue, violet, and burgundy depending on the viewing angle—a phenomenon known as pleochroism.
Tanzanite ranks around 6 to 7 on the Mohs scale of hardness, making it suitable for a variety of jewelry pieces, especially when handled with care. Its vibrant color and relative rarity have made it a sought-after gemstone for collectors and jewelry lovers alike.
