Tanzania’s Tanzanite: A Gemstone of Profundity

What is Tanzanite Stone?

An unusual variation within the ubiquitous mineral zoisite, tanzanite, is colored by strontium atoms. Pleochroism, a distinct and potent property, enables tanzanite to display two distinct hues simultaneously. Especially in the Tanzanian Merelani Hills, you can find it on the earth. That represents a precious stone that is extremely uncommon and prized for its beautiful blue-violet hue. It gets its name from its native Tanzania as well as being a member of the mineral genus Zoisite. 

Where Does it Come From?

Tanzanite stone , as the name suggests, comes exclusively from the East African country of Tanzania. More specifically, the gemstone is found in a small region near the foothills of Mount Kilimanjaro in the Mererani Hills of northern Tanzania. 

Tanzanite’s discovery is relatively recent compared to many other gemstones. In 1967, a Massai tribesman named Jumanne Ngoma came across transparent blue crystals while searching for rubies in the Mererani Hills. The crystals were initially thought to be a blue variety of the mineral zoisite, but further examination revealed them to be a new gemstone. Tiffany & Co., the renowned jewelry company, named the gem “Tanzanite” and introduced it to the international market in 1968.

Unique Qualities of Tanzanite Gemstones

Tanzanite is a gemstone that possesses several unique qualities that set it apart from other gemstones. Let’s explore some of these distinctive qualities:

Enchanting Color: One of the most exceptional qualities of Tanzanite is its mesmerizing color.

Pleochroism: Tanzanite exhibits a remarkable optical property known as pleochroism. This means that the gemstone can display different colors when viewed from different angles. Tanzanite can show blue, violet, and burgundy colors depending on the orientation.

Trichroism: Tanzanite is trichroic, which means it exhibits three distinct colors. The gemstone can display blue, violet, and burgundy colors simultaneously. The intensity and combination of these colors can vary, making each Tanzanite stone truly unique and individual.

Pleasing Clarity: Tanzanite gemstones often possess a pleasing level of clarity. While some stones may contain natural inclusions, which are characteristic of the gem, high-quality Tanzanite exhibits good transparency and minimal visible imperfections.

Heat Sensitivity: Unlike many other gemstones, Tanzanite is sensitive to high temperatures. When subjected to extreme heat, Tanzanite can undergo color changes or even become damaged. Therefore, it is crucial to handle Tanzanite with care and avoid exposing it to sudden temperature fluctuations or high heat sources.

How to Identify Genuine Tanzanite Gemstone

Determining a genuine Tanzanite gemstone can be a challenging task, especially considering the presence of synthetic or imitation Tanzanite in the market. 

Here are some guidelines to help you identify genuine Tanzanite:

  • Tanzanite is renowned for its unique blue-violet color. Look for a vibrant, vivid hue that ranges from deep blue to violet or purple. 
  • Observe the gemstone under different lighting conditions and angles to see if it shows a trichroic effect, typically displaying blue, violet, and burgundy hues simultaneously.
  • Genuine Tanzanite gemstones often possess some inclusions or internal characteristics known as “silk.” These silk-like inclusions are a natural feature of Tanzanite and contribute to its unique appearance. 
  • Genuine Tanzanite should allow light to pass through with good clarity, allowing you to see any inclusions or internal characteristics.
  • If you are unsure about the authenticity of a Tanzanite gemstone, seek the assistance of a qualified gemologist or jeweler with expertise in colored gemstones. 
  • Remember, it is essential to purchase Tanzanite gemstones from reputable and trustworthy sources to ensure their authenticity.
