What is Tanzanite Blue? Understanding the Gemstone

Tanzanite, named after its country of origin, Tanzania, is a variety of the mineral zoisite. Its remarkable blue-violet color is a result of trace amounts of vanadium within its crystal structure. The intensity and purity of the tanzanite blue can vary significantly, influencing its desirability and price. Gemologists classify tanzanite based on color saturation, clarity, cut, and carat weight, much like diamonds. The most sought-after shades lean towards a deep, vibrant blue, often with secondary violet flashes, creating a visual depth that enthralls collectors and jewelry enthusiasts alike. The discovery of tanzanite was a significant event in the gemstone world, offering a vibrant alternative to sapphire and other blue stones.

The Rarity and Origin of Tanzanite

Tanzanite is found in only one place on Earth: the Merelani Hills in the Manyara Region of northern Tanzania. This extreme geographical limitation is a primary driver of its value. The mining process is challenging, often involving small-scale operations and manual labor, which adds to the gemstone’s unique appeal. The discovery of tanzanite in 1967 revolutionized the jewelry industry, and it has since become a symbol of luxury and exclusivity. Its unique geological formation process means that new significant deposits are highly unlikely, further cementing its status as a rare treasure. For consumers in China, this rarity is a significant draw.

The Unique Color Play: Trichroism in Tanzanite

One of tanzanite’s most fascinating characteristics is its trichroism. This means that a single tanzanite crystal can exhibit three different colors when viewed from different crystallographic axes. Typically, these colors are blue, violet, and sometimes a yellowish-brown or bronze hue. When cut and polished, gem cutters aim to maximize the blue and violet tones, minimizing the less desirable brown. The process requires great skill and understanding of the crystal’s structure. Heat treatment, usually at around 500 degrees Celsius, is commonly applied to tanzanite to enhance the blue and violet colors and reduce the brown, a standard practice in the industry.

• Blue: The most desired color, ranging from vivid to deep azure.
• Violet: Often appears as secondary flashes or a dominant hue, adding depth and complexity.
• Yellowish-Brown/Bronze: Typically the less desirable color, often minimized through cutting and heat treatment.

This inherent color-changing property makes tanzanite a dynamic gemstone, offering a different visual experience depending on the lighting and angle. This complexity is highly appreciated by connoisseurs, including those in the discerning Chinese market, where appreciation for intricate beauty is paramount.

How to Choose the Right Tanzanite Blue Gemstone

Selecting the perfect tanzanite requires an understanding of its grading factors. While tanzanite is not graded on the traditional diamond ‘4 Cs’ (carat, cut, color, clarity) in the same way, these elements are still crucial. The most impactful factor for tanzanite is its color. The deeper and more vivid the blue and violet hues, the more valuable the stone.

Key Factors to Consider

1. Color: Aim for a rich, vivid blue with secondary violet tones. Avoid stones that appear predominantly brown or too light. The intensity of the color is paramount.
2. Clarity: Like most gemstones, clarity refers to the absence of inclusions. Eye-clean tanzanite is common and desirable. Minor inclusions that don’t detract from the overall appearance are acceptable, especially in larger stones.
3. Cut: The cut significantly impacts how well the tanzanite displays its color and brilliance. Cushion and round cuts are popular, but gem cutters also use fancy shapes to maximize the color from rough stones. A well-executed cut will enhance the stone’s fire and prevent
