Tanzanite is a gemstone known for its rare and captivating beauty. Discovered relatively recently, this exquisite blue-violet gemstone has captured the hearts of jewelry enthusiasts and collectors alike. In this comprehensive article, we delve into the allure of tanzanite, exploring its unique qualities, historical significance, sources, grading criteria, and its remarkable journey from the foothills of Mount Kilimanjaro to the world stage.
The Discovery of Tanzanite
Tanzanite’s remarkable journey begins in Tanzania, East Africa. In 1967, a Masai tribesman named Ali Juuyawatu stumbled upon a striking blue-violet crystal while searching for food in the Merelani Hills near Mount Kilimanjaro. Initially mistaken for sapphire due to its vibrant blue hue, this gemstone would later become known as tanzanite.
What makes tanzanite truly exceptional is its geological uniqueness. Tanzanite is a variety of the mineral zoisite, and its mesmerizing blue-violet color is the result of vanadium impurities within the crystal structure. This geological occurrence is incredibly rare, and the conditions required for tanzanite’s formation are limited to a small area in northern Tanzania.
The Unique Qualities of Tanzanite
The following are the unique qualities of tanzanite:
1. Exquisite Color Play
Tanzanite is celebrated for its enchanting color range, which spans from a delicate lavender-blue to a deep, velvety violet-blue. The most coveted tanzanite gems exhibit a rich, saturated hue with excellent transparency. The gem’s color can shift under different lighting conditions, revealing captivating flashes of blue, violet, and sometimes even burgundy.
2. Trichroism
One of tanzanite’s distinctive features is its trichroism, which means it can exhibit three different colors when viewed from various angles. This property adds an element of intrigue to the gemstone, as it showcases a kaleidoscope of hues depending on how it is oriented.
3. Pleochroism
Tanzanite also displays pleochroism, where it shows different colors when viewed along different crystal axes. This phenomenon contributes to the gem’s complex and ever-changing appearance, making it an appealing choice for jewelry designers seeking unique and dynamic gemstones.
4. Luster and Clarity
Tanzanite boasts a vitreous to subadamantine luster, which imparts a brilliant sparkle to the gem. Clarity is an essential factor in evaluating tanzanite quality, with eye-clean specimens being highly prized. These gems are devoid of visible inclusions, allowing light to pass through unhindered and maximizing their brilliance.
Factors Affecting Tanzanite Valuation
Several factors influence the valuation of tanzanite:
1. Color Saturation:
The richness and intensity of the gem’s color significantly impact its value. Deep, vivid blues and violets command higher prices.
2. Size:
Larger tanzanite gems are less common and, consequently, more valuable on a per-carat basis.
3. Clarity:
Gems with fewer visible inclusions are generally more valuable than those with noticeable imperfections.
4. Cut Quality:
A well-cut tanzanite maximizes its visual appeal and, therefore, its value.
5. Treatment:
Tanzanite is often heat-treated to enhance its color. Proper disclosure of any treatments is crucial for accurate valuation.
