Tanzanites are a rare and valuable gemstone known for their mesmerizing hues of blue and violet. They are a variety of the mineral zoisite and are found only in a small mining area near the Merelani Hills in Tanzania, East Africa.

Tanzanites are relatively new to the gemstone world, having only been discovered in 1967. Since then, they have gained immense popularity among jewelry lovers and collectors for their unique color and exceptional brilliance.

The color of a tanzanite can range from deep blue to violet-blue, with the most prized stones having a vivid and intense blue hue. Tanzanites also have a distinctive property called pleochroism, which means that they exhibit different colors when viewed from different angles. This quality adds to the gemstone's beauty and makes each stone truly one-of-a-kind.
