Tanzanite, a gemstone with a rich history and a relatively recent introduction to the world of gemology, has captivated enthusiasts with its mesmerizing hues. One of the key factors that contribute to the allure of tanzanite is its range of colors, each with its own level of rarity and beauty. This article delves into the captivating world of tanzanite colors, exploring what makes certain hues rare and sought after.

I. Introduction to Tanzanite’s Color Spectrum

Before delving into the rarity of tanzanite colors, it’s crucial to understand the gemstone’s natural color range. Tanzanite is a variety of the mineral zoisite and is renowned for its blue to violet hues. The gemstone’s color spectrum encompasses a gradient that ranges from pale blue to intense violet, with various shades and saturations in between.


II. The Three Primary Tanzanite Colors

Tanzanite’s colors are typically categorized into three primary hues: blue, violet-blue, and violet. Each of these colors has its own unique appeal, and the rarity of a particular shade depends on several factors.


A. Blue Tanzanite: The blue variety of tanzanite is characterized by a cool, calming hue reminiscent of the sky. Blue tanzanite is often associated with tranquility and is prized for its soothing and serene appearance. While blue tanzanite is considered rare, its availability is greater compared to the violet and violet-blue varieties.


B. Violet-Blue Tanzanite: Violet-blue tanzanite represents a combination of blue and violet tones, creating a captivating and vibrant color. This is one of the most sought-after and popular colors in the tanzanite spectrum. The delicate balance of blue and violet hues contributes to the gemstone’s allure, making it highly desirable among collectors and jewelry enthusiasts.

C. Violet Tanzanite: The pure violet tanzanite is the rarest and most prized among the three primary colors. Tanzanite with a predominantly violet hue without significant blue undertones is considered exceptionally rare. This deep and rich color is often associated with regality and sophistication.

III. Factors Influencing Tanzanite Color Rarity

Several factors contribute to the rarity and value of tanzanite colors. Understanding these factors provides insight into why certain hues are considered more exceptional and sought after in the world of tanzanite.

A. Intensity of Color: The intensity or saturation of color is a crucial factor in determining the rarity of tanzanite. Stones with vivid and saturated hues are considered more valuable. In the case of blue tanzanite, a deeper and more intense blue is often rarer. For violet and violet-blue tanzanite, a rich and vibrant color is highly sought after.

B. Pleochroism: Tanzanite exhibits pleochroism, meaning it can display different colors when viewed from different angles. The degree of pleochroism can affect the perceived color of the gemstone. Stones with minimal pleochroism and a consistent color throughout are often more desirable.

C. Clarity: The clarity of a tanzanite gemstone, referring to the presence or absence of inclusions, impacts its overall appearance. Stones with high clarity, particularly those that are eye-clean (no visible inclusions to the naked eye), are generally considered more valuable.

D. Cut: The cut of a tanzanite gemstone influences how light interacts with it, affecting its brilliance and color. A well-cut tanzanite should showcase its color to its best advantage. Poorly cut stones may appear dull or lackluster, diminishing their overall rarity.

E. Carat Weight: While the carat weight of a tanzanite is not directly tied to its color, larger stones with exceptional color are rarer and can command higher prices. However, smaller stones with intense and rare colors can also be highly valued.

IV. The Rarity of Pure Violet Tanzanite

Among the three primary tanzanite colors, pure violet tanzanite stands out as the rarest and most elusive. The depth and richness of violet without significant blue undertones are highly sought after by collectors and connoisseurs of fine gemstones. The scarcity of pure violet tanzanite can be attributed to the geological conditions that lead to the formation of tanzanite.

A. Geological Factors: The formation of tanzanite is a result of specific geological conditions, including the presence of vanadium, iron, and titanium. The ratio of these elements in the Earth’s crust influences the color of the tanzanite formed. Pure violet tanzanite requires a precise combination of these elements, making it less common compared to other color variations.

B. Mining Challenges: Tanzanite is mined in a single location—the Merelani Hills of Tanzania. Mining conditions can be challenging, and the availability of gem-quality tanzanite is limited. The rarity of pure violet tanzanite is compounded by the finite nature of the tanzanite deposits in this region.

C. Collector’s Appeal: For gemstone collectors and investors, pure violet tanzanite holds a special appeal. The rarity of this color variation makes it a prized addition to gemstone portfolios, and the scarcity contributes to its exclusivity.

V. The Allure of Violet-Blue Tanzanite

Violet-blue tanzanite, often considered the most desirable and popular color, combines the best of both the blue and violet spectrums. The delicate balance of hues creates a mesmerizing and dynamic color that appeals to a broad range of consumers.

A. Popularity in Jewelry: Violet-blue tanzanite is a favorite choice for jewelry designers and buyers alike. The color’s versatility allows it to complement various metals and settings, making it an ideal gemstone for a wide range of jewelry pieces, from rings and earrings to pendants and bracelets.

B. Evoking Emotion: The color of violet-blue tanzanite is often associated with emotions such as calmness, sophistication, and creativity. Its vibrant yet soothing appearance makes it a popular choice for individuals seeking a gemstone that evokes a sense of beauty and tranquility.

C. Value and Investment: While violet-blue tanzanite is more readily available than pure violet, stones with exceptional saturation and vibrancy are still highly valued. The popularity of this color variation contributes to its consistent demand in the gemstone market.

VI. The Appeal of Blue Tanzanite

Blue tanzanite, though more readily available than violet and violet-blue variations, holds its own appeal for those seeking a gemstone with a serene and calming presence.

A. Classic Elegance: Blue tanzanite exudes a classic elegance that makes it a timeless choice for jewelry. Its cool and tranquil blue hues are reminiscent of clear skies and calm waters, adding a touch of sophistication to any piece.

B. Accessibility: While considered rarer than some other blue gemstones, blue tanzanite is more accessible compared to its violet counterparts. This accessibility makes it a popular choice for individuals looking for a unique blue gemstone without venturing into the higher price ranges.

C. Versatility in Design: Blue tanzanite’s versatility allows it to be set in a variety of designs and styles. Whether in a simple solitaire setting or as the focal point of an intricate design, blue tanzanite can adapt to different aesthetics.

VII. The Role of Tanzanite Treatments in Color Enhancement

It’s important to note that tanzanite often undergoes heat treatment to enhance its color. This common industry practice is accepted and does not negatively impact the value or authenticity of the gemstone. Heat treatment is used to remove brownish or yellowish hues, intensifying the blue and violet tones that make tanzanite so desirable.

A. Industry Acceptance: Heat treatment is widely accepted in the gemstone industry and is disclosed to buyers. When purchasing tanzanite, it’s essential to be aware of any treatments the gemstone may have undergone and to obtain this information from reputable sellers.

B. Impact on Rarity: While heat treatment does enhance the color of tanzanite, it does not artificially create rare colors. The rarity of certain tanzanite colors, such as pure violet, is primarily influenced by the natural conditions under which the gemstone forms.

VIII. Collecting and Investing in Rare Tanzanite Colors

For collectors and investors intrigued by the rarity of tanzanite colors, considerations extend beyond aesthetic preferences to potential future value appreciation.

A. Rarity as an Investment: The rarity of certain tanzanite colors, particularly pure violet, can contribute to their appeal as investments. As the global supply of high-quality tanzanite diminishes, rare color variations may become increasingly valuable over time.

B. Market Trends: Monitoring market trends and staying informed about developments in the tanzanite industry can provide insights into the potential value trajectory of rare tanzanite colors. While trends can fluctuate, a long-term perspective may guide investment decisions.

C. Certifications and Documentation: When acquiring rare tanzanite colors for investment purposes, obtaining gemstone certifications and detailed documentation is crucial. This documentation serves as proof of the gemstone’s rarity, authenticity, and characteristics, enhancing its value in the market.

IX. The Impact of Lighting on Tanzanite Colors

The appearance of tanzanite colors can be influenced by the type of lighting under which they are viewed. Understanding these nuances adds another layer to the appreciation and assessment of tanzanite.

A. Natural vs. Artificial Light: Tanzanite colors may appear differently under natural sunlight compared to artificial lighting. Natural light often brings out the true vibrancy and saturation of the colors, while some artificial lighting may alter the perceived hues.

B. Pleochroism in Different Lights: Tanzanite’s pleochroic nature means that it can exhibit different colors when viewed from different angles. Observing tanzanite in various lighting conditions allows for a more comprehensive understanding of its color range.

C. Choosing Based on Personal Preferences: When selecting a tanzanite gemstone or piece of jewelry, it’s advisable to view it under different lighting conditions to ensure that the chosen color aligns with personal preferences.
