How much is a 5 carat tanzanite worth?

Tanzanite, with its mesmerizing blue-violet hues, is a gemstone that has captivated gem enthusiasts and collectors alike. Its rarity and unique color make it highly sought after in the gemstone market. One of the key factors in determining the value of tanzanite is its carat weight, with larger stones commanding higher prices. In this comprehensive guide, we will explore the factors that influence the worth of a 5-carat tanzanite, providing you with a detailed understanding of its current market prices, quality determinants, price calculations, investment potential, historical price trends, and buying tips.


Current Market Prices

The current market price of tanzanite can vary significantly based on several factors, including its quality, color, clarity, and cut. As of 2024, tanzanite prices have shown a tendency to fluctuate due to changing market conditions and supply dynamics.


Quality and Color

The most crucial determinant of tanzanite’s price is its color. Tanzanites with a deep, vivid blue-violet color are the most valuable. Stones that exhibit a rich, saturated hue with minimal brown or gray undertones are considered top quality. The presence of strong pleochroism, where the stone exhibits different colors when viewed from different angles, also adds to its desirability and price.

Clarity and Cut

Clarity refers to the presence of inclusions or internal flaws within the stone. Tanzanites with fewer inclusions are more valuable. A high-quality cut enhances the stone’s brilliance and maximizes its visual appeal, contributing to a higher price.

Current Price Range

As of 2024, the price of a 5-carat tanzanite can range from $2,000 to $10,000 per carat, depending on its quality. Exceptional stones with top color and clarity can even exceed this range. Therefore, a 5-carat tanzanite of excellent quality could be worth between $10,000 and $50,000 or more.

Quality Factors

The quality of tanzanite is assessed based on several factors, which collectively determine its overall value in the market. Understanding these factors is essential for anyone looking to buy or invest in tanzanite.


Color is the most critical factor in determining tanzanite’s value. The finest tanzanites exhibit a deep, velvety blue with violet undertones. Lesser quality stones may appear lighter or have undesirable brown or gray tints.


High clarity tanzanites, free from visible inclusions or internal flaws, are more valuable. However, tanzanites typically have fewer inclusions compared to other gemstones, making clarity less of a differentiator than color.


The cut of tanzanite significantly impacts its appearance and brilliance. A well-cut tanzanite will display its pleochroic colors to the fullest, enhancing its visual appeal. Common cuts for tanzanite include oval, cushion, and emerald cuts.

Carat Weight

Larger tanzanites are rarer and more valuable. As carat weight increases, the price per carat also rises. This makes a 5-carat tanzanite significantly more valuable than smaller stones.


Tanzanite is exclusively found in Tanzania, specifically in the Mererani Hills near Mount Kilimanjaro. The stone’s unique geographical origin adds to its rarity and value.

Price Calculations

Calculating the price of a 5-carat tanzanite involves considering all the quality factors and their impact on the stone’s value. Here’s a step-by-step guide to understanding price calculations for tanzanite.

Determining Base Price

Start by determining the base price per carat for tanzanite of the desired quality. For example, if top-quality tanzanite is priced at $5,000 per carat, this serves as the base price.

Applying Multipliers

Factors such as exceptional color, superior clarity, and a high-quality cut can increase the base price. For instance, a tanzanite with exceptional color and clarity might have a multiplier of 1.5 applied to its base price.

Carat Weight Adjustment

Since larger tanzanites are more valuable, the price per carat increases with carat weight. A 5-carat tanzanite will typically be more expensive per carat than a 1-carat stone. This is accounted for in the final price calculation.

Example Calculation

If a top-quality 5-carat tanzanite has a base price of $5,000 per carat, and a multiplier of 1.5 is applied for exceptional quality, the price per carat becomes $7,500. Therefore, the total value of the 5-carat tanzanite would be $7,500 x 5 = $37,500.

Investment Potential

Tanzanite’s unique qualities and limited supply make it an attractive investment for gemstone enthusiasts. Here are some key points to consider regarding its investment potential.

Rarity and Supply Constraints

Tanzanite is only found in a small area in Tanzania, making it significantly rarer than many other gemstones. The finite supply and potential for depletion in the future contribute to its investment appeal.

Market Demand

The demand for tanzanite has grown steadily, driven by its unique color and rarity. Increased awareness and appreciation for this gemstone can lead to higher prices over time.

Historical Performance

Historically, tanzanite prices have shown an upward trend, particularly for high-quality stones. While the market can experience fluctuations, the overall trajectory has been positive, making it a potentially lucrative investment.

Long-Term Outlook

With limited new sources of tanzanite and increasing global demand, the long-term outlook for tanzanite investments appears promising. Investors who choose high-quality stones and hold them over time are likely to see substantial returns.

Historical Price Trends

Understanding the historical price trends of tanzanite can provide valuable insights into its market behavior and future potential.

Early Discoveries

Tanzanite was discovered in the late 1960s, and its initial prices were relatively low due to limited awareness and demand. However, as the gemstone gained popularity, prices began to rise.

Price Fluctuations

Over the decades, tanzanite prices have experienced fluctuations due to changes in supply, market demand, and economic conditions. Major events, such as the global financial crisis, have also impacted gemstone prices.

Recent Trends

In recent years, the price of high-quality tanzanite has increased steadily. The combination of limited supply, rising demand, and enhanced marketing efforts has contributed to this upward trend.

Future Projections

Looking ahead, experts predict continued appreciation in tanzanite prices, particularly for stones of exceptional quality. The gemstone’s rarity and unique appeal make it a strong candidate for future price growth.
