Understanding the Best Color of Tanzanite

October 8, 2024 4:06 am Published by

When you’re buying tanzanite and seeking “the best color,” what exactly does that mean? Tanzanite is celebrated for its stunning color range, making it a favorite among gemstone enthusiasts. From light sky blues and lilacs to deep indigos and royal blues, the color of tanzanite significantly influences its value.

Lighter vs. Darker Tanzanite: Which One is “Better”?

When comparing lighter tanzanite to darker tanzanite, the answer to which is “better” is no. Lighter tanzanite is generally more common, while darker tanzanite is rarer and typically more expensive. However, the best color of tanzanite is ultimately the one that resonates with you personally, as beauty is subjective.

In essence, while darker, more saturated tanzanite often holds higher value, the right choice for you depends on your individual taste and preference. Embrace the color that captivates you, whether it’s a soft pastel or a rich, deep hue.

Size Matters

It’s important to note that smaller tanzanites are usually lighter in color. The richest hues are often found in stones over 5 carats. However, a larger stone with less saturation may not hold the same value as a smaller, more vibrant gem.

Just as a glass of water can never be as dark as the ocean, a 2-carat tanzanite will never match the depth of color found in a 20-carat stone. Both may be beautiful, but the scale and saturation vary significantly.

Color Spectrum

The ideal tanzanite exhibits a rich, vibrant hue, with deep blue and violet being the most sought after. Larger stones typically showcase the most intense colors, while smaller tanzanites tend to be lighter. Here’s a breakdown of the key color classifications:

  • Bluish-Violet (bV): This classification indicates a tanzanite with more violet than blue, offering a lovely blend that some buyers prefer.
  • Violetish-Blue (vB): This type shows greater dominance of blue, often regarded as the more desirable option due to its striking appearance.

Is Violet Tanzanite Less Expensive than Blue Tanzanite?

In the marketplace, there is generally no price difference between violet-dominant and blue-dominant tanzanite. While confusingly some ( very reputable)  websites may suggest otherwise, the value of tanzanite is primarily determined by the overall quality, saturation, and clarity of the stone rather than its color dominance.

Pleochroism: A Unique Feature

One remarkable characteristic of tanzanite is its pleochroism, which means it can display two colors simultaneously. Depending on the angle, you may notice both blue and violet hues, enhancing the stone’s complexity and allure. Occasionally, larger tanzanites may also reveal flashes of burgundy, adding depth to the color experience.

Grading Systems  

No standard quality grading scales exist for tanzanite – or any other colored stone. Diamonds are the only gemstone with a universally applied grading system. As a result, there is a bewildering array of terms used on the internet to describe tanzanite, most of which are entirely subjective and based on the author’s personal opinion, education, and commercial motives. This fact makes it very important for consumers to buy from a trusted source.

D Block  & “AAA+” TANZANITE

These two phrases are very commonly used online to imply high value and superior quality, but in reality, they have no scientific basis whatsoever and should not be taken as a guarantee of quality.

Conclusion

When choosing a tanzanite, prioritize deep, saturated colors—especially vivid blue and violet—as they signify quality and rarity. Remember, while a deep violetish-blue may be stunning, each tanzanite has its unique beauty, so personal preference should guide your selection.

By understanding these key aspects of tanzanite color, you can make an informed decision and choose a gemstone that truly resonates with you.
