The History of Tanzanite

Tanzanite, a breathtakingly beautiful gemstone, was first discovered in the foothills of Mount Kilimanjaro in northern Tanzania in the late 1960s. Its stunning blue-violet hue immediately captured the attention of gem enthusiasts worldwide. Tanzanite is now cherished for its rarity and exceptional beauty.

The Properties of Tanzanite

Tanzanite is a variety of the mineral zoisite and belongs to the epidote group. This extraordinary gemstone exhibits trichroism, meaning it displays three different colors when viewed from different angles: blue, violet, and burgundy. The finest tanzanite gemstones showcase a vibrant blue hue with purple undertones.

One remarkable characteristic of tanzanite is its pleochroism, which refers to its ability to exhibit different colors when seen from different crystallographic directions. This distinct property contributes to the stone's allure and makes it highly sought after by collectors and jewelry connoisseurs.

The Geological Formation of Tanzanite

Tanzanite is formed under incredible geological conditions. It is created when the mineral zoisite undergoes intense heat and pressure during the metamorphic transformation of limestone. The presence of vanadium and other trace elements imparts the unique blue color to tanzanite.

What makes tanzanite even more exceptional is that its primary source is confined to a small mining area near Mount Kilimanjaro. This limited geographical occurrence adds to its rarity and makes it a prized gemstone among jewelry enthusiasts.

The Value of Tanzanite

Tanzanite's extraordinary beauty and limited supply contribute to its high value. The value of tanzanite is determined by various factors, including color, clarity, carat weight, and cut.

The most valuable tanzanite gemstones possess a vivid blue color, with a rich saturation and minimal secondary hues. The absence of visible inclusions greatly enhances the stone's clarity and thus its value. Larger tanzanite gemstones are rarer and command higher prices, especially when they possess exceptional color and clarity.

Tanzanite is often faceted as a cushion or oval cut to maximize its brilliance and showcase its unique color properties. A well-cut tanzanite gemstone will exhibit superior light reflection and dispersion, further adding to its value.

How to Purchase Authentic Tanzanite

When looking to purchase authentic tanzanite, it is crucial to buy from reputable and trusted sources. Due to its rarity, some unscrupulous individuals may attempt to sell synthetic or counterfeit tanzanite gemstones.

Here are a few tips to ensure you are buying genuine tanzanite:

  1. Shop from established jewelers or renowned online stores specializing in gemstones.
  2. Request a certificate of authenticity from a reputable gemological laboratory, such as the Gemological Institute of America (GIA).
  3. Examine the gemstone for visible inclusions or flaws, which are typical of natural tanzanite.
  4. Ask for detailed information about the gemstone's origin, preferably with proof of responsible mining practices.

The Healing Properties and Metaphysical Meaning of Tanzanite

In addition to its extraordinary beauty, tanzanite is believed to possess various healing properties and metaphysical meanings. It is said to promote spiritual insight, clarity of mind, and a deep connection with one's inner self.

Tanzanite is also associated with physical healing and is believed to assist with ailments such as stress, anxiety, and emotional trauma. Some gemstone enthusiasts believe that tanzanite can enhance intuition, creativity, and bring a sense of balance and harmony into one's life.


Tanzanite, with its unrivaled beauty and fascinating properties, has secured its place as one of the world's most desirable gemstones. Its rarity, exquisite color, and metaphysical attributes make it a captivating choice for jewelry collectors and individuals seeking a truly unique and precious gemstone.
