Tanzanite, a rare and mesmerizing gemstone discovered in Tanzania in the 1960s, has gained immense popularity for its captivating blue and violet hues. Its rarity and unique color-changing properties have made it highly sought after in the world of gemstones. When it comes to determining the value of tanzanite, the color plays a pivotal role. In this comprehensive guide, we will explore the intricate nuances of tanzanite color, its grading, and how it impacts the gemstone’s value.
I. Understanding Tanzanite Color
Before delving into the intricacies of tanzanite color grading and value, it’s essential to grasp the fundamentals of the gemstone’s color range.
1. Natural Color Spectrum
Tanzanite is a member of the zoisite mineral family, and its natural color spans a range from blue to violet. This variance in color is caused by the presence of trace elements like vanadium and chromium during its formation. The gem’s color can shift depending on lighting conditions and the angle from which it’s viewed, making it a captivating and dynamic gemstone.
2. Three Primary Color Zones
Tanzanite is typically divided into three primary color zones:
a. Blue Tanzanite: Ranging from pale blue to deep, rich blue, this is the most common and beloved color for tanzanite. Deep blue tanzanite with violet undertones is often considered the most desirable and valuable.
b. Violet Tanzanite: This variety showcases a predominantly violet hue with blue undertones. While less common than blue tanzanite, high-quality violet tanzanite can be exceptionally valuable.
c. Bluish-Violet Tanzanite: Tanzanite that falls between the blue and violet color zones is also highly sought after. These gemstones display an enchanting blend of both colors.
II. Tanzanite Color Grading
To determine the value of tanzanite, gemologists and laboratories use a color grading system that takes into account the gem’s hue, tone, and saturation.
1. Hue
a. Blue: The most valuable tanzanites often have a primary hue of blue with secondary hues of violet.
b. Violet: Tanzanites with a predominant violet hue are prized for their uniqueness, and the most valuable ones exhibit pure violet without any noticeable blue.
2. Tone
a. Light: Tanzanite with a light tone may appear pastel and less vibrant. While it can be attractive, it is generally less valuable.
b. Medium: Medium-toned tanzanite strikes a balance, displaying the gem’s color with good saturation and brightness.
c. Dark: Dark-toned tanzanite may lose some of its brilliance and can appear less desirable.
3. Saturation
a. Low Saturation: Tanzanites with low saturation may appear dull and lackluster. They are generally less valuable.
b. Medium Saturation: Most tanzanites fall into this category, displaying a good balance of color intensity without being overly dark or pale.
c. High Saturation: Highly saturated tanzanite exhibits intense and vibrant color, making it the most valuable.

The most valuable tanzanite color is a deep, rich blue with violet undertones. This coveted hue is often referred to as “cornflower blue” or “royal blue.” Tanzanites that exhibit this color profile are exceptionally rare and highly sought after by collectors and connoisseurs.
IV. Factors Affecting Tanzanite Color
Several factors can influence the color of tanzanite, thus impacting its value:
1. Cut Quality:
A well-cut tanzanite can enhance its color by maximizing the reflection and refraction of light within the gemstone.
2. Lighting Conditions:
Tanzanite’s color can appear different under various lighting conditions. Natural daylight often brings out the best in its color, but gemstone enthusiasts should also appreciate its beauty under artificial lighting.
3. Heat Treatment:
Many tanzanites undergo mild heat treatment to improve their color. This is a generally accepted practice in the industry, and properly treated tanzanites can exhibit stunning color.
V. Tanzanite Color and Market Value
The market value of tanzanite is intrinsically tied to its color, among other factors. As mentioned earlier, the most valuable tanzanites feature a deep blue color with violet undertones. These gems command premium prices due to their rarity and exquisite aesthetics.
Violet tanzanite, with a predominantly violet hue, is also highly prized and valuable. Its uniqueness and desirability among collectors make it an attractive investment.
Bluish-violet tanzanite, which combines both blue and violet hues, offers a captivating blend of colors and can be a popular choice among those seeking an elegant and distinctive gemstone.
However, it’s essential to note that personal preference also plays a significant role in determining value. Some individuals may prefer the purity of a blue tanzanite, while others may be drawn to the allure of a violet or bluish-violet tanzanite.
