Its discovery was relatively recent, and it has since become a celebrated addition to the world of gemstones.

Geological Formation and Sources
Tanzanite's geological origin is as unique as its color. It is found exclusively in a single location in Tanzania, making it the rarest of all birthstones. This limited geographic source contributes to its value and desirability among collectors and gemologists. The gemstone is a variety of the mineral zoisite and is known for its distinctive pleochroism, a property that causes it to display different colors when viewed from different angles.
The gemstone's formation process involves the interaction of specific minerals under unique geological conditions. While the exact details of its formation are not extensively covered in the provided sources, the rarity of its occurrence underscores its special status in the gemological world. The fact that it is found in only one location on Earth makes it a subject of fascination for geologists and gem enthusiasts alike.
Gemological Properties
Tanzanite possesses a range of gemological properties that contribute to its visual appeal and value. It is known for its pleochroism, which means it can show different colors—typically blue and violet—depending on the direction from which it is viewed. This property makes it a fascinating subject of study and a prized characteristic in jewelry design.
The gemstone's hardness on the Mohs scale is between 6 and 7, making it relatively durable but still requiring careful handling to avoid scratches and damage. Its refractive index and specific gravity are other important properties that contribute to its brilliance and weight. While specific numerical values for these properties are not provided in the sources, the mention of these characteristics highlights tanzanite's unique gemological profile.
The color of tanzanite is one of its most defining features, ranging from a deep blue to a vibrant violet. This captivating hue is a result of its chemical composition and the geological conditions under which it formed. The gemstone's color is often enhanced through heat treatment, a common practice in the gemstone industry to bring out the most desirable shades.

Care and Cleaning
Proper care and cleaning are essential to maintain the beauty and longevity of tanzanite. With a hardness of 6 to 7 on the Mohs scale, it is relatively durable but can be susceptible to scratches and damage if not handled with care. It is recommended to clean tanzanite jewelry using mild soap, warm water, and a soft brush. Avoid using harsh chemicals or ultrasonic cleaners, as these can damage the stone.
When storing tanzanite, it should be kept separately from other gemstones to prevent scratching. It is also advisable to remove tanzanite jewelry during activities that could expose it to physical impact or harsh conditions, such as sports or heavy manual work. By following these care guidelines, owners can ensure that their tanzanite jewelry remains vibrant and beautiful for years to come.
