Historical Background of Tanzanite
Tanzanite was discovered in 1967 in the Merelani Hills of Tanzania. This discovery marked a remarkable addition to the world of gemstones. The stone was first thought to be sapphire due to its striking blue-hued beauty but was later recognized as a unique variety of the mineral zoisite.

Gaining recognition, tanzanite was later designated as the official birthstone for December by the American National Retail Jewelers Association in 2002, further consolidating its place among significant gems.
The situated exclusivity of tanzanite adds to its historical intrigue. The availability of this gemstone is limited purely to its geographic source in Tanzania, making it rare and sought after.

Grasping this formation process enhances appreciation for tanzanite, both in terms of its aesthetic appeal and its valuable geological story.
The Unique Conditions for Formation
Tanzanite is a variety of the mineral zoisite, and the conditions necessary for its formation are both specific and rare. Mainly, these conditions include a unique convergence of heat and pressure over millions of years.
Two key factors play a role:
- Temperature: The formation of tanzanite occurs at 500 degrees Celsius and higher, a rich geological setting often not found globally.
- Pressure: Extreme pressure tends to occur during tectonic events, which further facilitates the synthesis of delightful colors in tanzanite.
Moreover, impurity elements such as chromium and vanadium add to its distinctive blue-to-purple coloring. It is worth noting how this remarkable blend of raw earth components is necessary for producing the striking gemstone known and loved today.
Location and Discovery in Tanzania
The exclusive availability of tanzanite is another factor that elevates its status. Discovered in 1967 in the Mirerani Hills of Tanzania, the only commercial site for tanzanite, these deposits significantly affected jewelry design and appreciation, specifically within the context of the gemstone trade.
Explorers like Manuel d'Souza stumbled upon this hidden treasure during the search for gold. The geologists' comprehensive understanding of the area's formation allows gem enthusiasts to appreciate the significance of tanzanite's roots.
Collectively, the conditions discussed—temperature, pressure, and location—underscore why tanzanite ranks high among coveted gemstones. Its formation took imperceptible and time-consuming processes, making each stone not only a piece of art but also a geological testimony of Earth’s history.
Physical Properties of Tanzanite
Tanzanite, as a gemstone, possesses various physical properties that are essential for understanding its value, aesthetic charm, and suitability for jewelry. The exploration of tanzanite’s physical properties reveals insights into its color, hardness, and optical characteristics. Each of these aspects plays a role in how the stone is appreciated by enthusiasts, jewelers, and collectors.


Color Variations and Causes
Tanzanite is well-known for its vibrant colors ranging from blue to violet, often displaying a combination of both. This breathtaking hue rises from the presence of certain trace elements. Specifically, vanadium is a key factor contributing to tanzanite's distinctive colors.
The color of tanzanite can change depending on the angle of light, leading to differing visual experiences under various conditions. This phenomenon is known as pleochroism. Given its unique color variations, it’s common for blue shades to dominate the market, yet the more rare and intense violet can fetch higher prices. Variations can also occur due to heat treatment, a common practice aimed at enhancing color saturation and consistency, generating a more visually appealing piece.
It’s intriguing to note how specific treatment methods can genuinely alter the perception of value in the gemstone market.
Hardness and Durability
Measuring 6 to 7 on the Mohs scale of mineral hardness, tanzanite is relatively softer compared to diamonds, sapphires, or rubies. This softness does present unique considerations for care and maintenance. In everyday settings, tanzanite can chip or scratch more easily than its harder gemstone counterparts. Thus, thought must be given to how and where it is worn, especially in rings or bracelets subject to frequent contact.
Despite its susceptibility to damage, tanzanite can still be a durable choice for special occasion jewelry. When set properly, widespread care can keep it looking stunning for years. To enhance its longevity, jewelry designers often recommend mounting tanzanite in protective settings, minimizing potential wear. This ensures the beauty of the stone is preserved for both near-term use and long-term enjoyment.
Optical Characteristics
The optical properties of tanzanite accentuate its appeal. Chief among these is a remarkable brilliance that results from the appropriate cut of the stone. Radiant and responsive to light, a well-faceted tanzanite exhibits a brilliance reminiscent of more precious gemstones.
