Is It A Good Idea To Invest In Tanzanite?

by Madonna

In the world of gemstones, few have captured the imagination of collectors and investors like Tanzanite. This strikingly beautiful blue and violet gem, discovered in the late 1960s, has quickly become one of the most sought-after stones for both its aesthetic appeal and its investment potential. But is investing in Tanzanite a wise financial move? This article will explore the various aspects of Tanzanite as an investment, including its market dynamics, value trends, and factors that influence its worth.

Rarity and Supply Constraints

One of the most compelling reasons to consider Tanzanite as an investment is its rarity. Unlike diamonds, which are found in various locations around the world, Tanzanite comes from a single source. The mining area is limited to a mere 14 square kilometers in the Mererani Hills of Tanzania. This geographic limitation means that the supply of Tanzanite is finite and potentially depletable.


The Tanzanian government has recognized the value of this unique resource and has taken steps to control its mining and export. This includes stricter regulations and higher taxes on Tanzanite exports, which can impact the stone’s availability and price on the global market. The controlled supply, coupled with increasing global demand, suggests that Tanzanite’s value could appreciate over time.


Market Dynamics

Demand Factors

The demand for Tanzanite is driven by several factors:


Jewelry Market: The primary driver of Tanzanite demand is the jewelry market. Its stunning color and rarity make it a favorite among jewelry designers and consumers. High-quality Tanzanite pieces are often featured in luxury jewelry collections, driving up demand.

Collector Interest: As a relatively new gemstone, Tanzanite has captured the interest of collectors. Many see it as a unique addition to their collections due to its rarity and the story behind its discovery.

Investment Potential: Investors are increasingly looking at Tanzanite as a tangible asset. The gemstone’s limited supply and increasing demand suggest it could be a good long-term investment.

Price Trends

Tanzanite prices have shown a general upward trend since its discovery, though there have been fluctuations due to various factors. In the initial years, prices were relatively low as the gemstone was not widely known. However, as awareness and demand grew, prices began to rise. The peak periods of price increases have often coincided with major promotional efforts and increased visibility in the jewelry market.

Economic factors, such as global recessions or economic booms, also impact Tanzanite prices. During economic downturns, luxury goods, including gemstones, often see a dip in demand, leading to lower prices. Conversely, during economic growth periods, the demand for luxury items increases, pushing prices higher.

Investment Considerations

Pros of Investing in Tanzanite

Rarity: Tanzanite’s limited supply is a significant factor that could drive its value higher over time. As the only source of Tanzanite is mined out, the scarcity will likely make existing stones more valuable.

Aesthetic Appeal: Tanzanite’s unique color and beauty make it highly desirable in the jewelry market. This ensures a consistent demand, which is essential for any investment.

Diversification: Including Tanzanite in an investment portfolio can provide diversification. Tangible assets like gemstones often have a low correlation with traditional financial assets, such as stocks and bonds.

Cons of Investing in Tanzanite

Market Volatility: The gemstone market can be volatile, with prices subject to fluctuations based on supply and demand dynamics, economic conditions, and changes in consumer preferences.

Liquidity Issues: Unlike stocks or bonds, Tanzanite is not a highly liquid asset. Selling gemstones can take time, and finding buyers willing to pay the desired price can be challenging.

Quality and Certification: The value of Tanzanite can vary significantly based on its quality. Factors such as color, clarity, and cut all play a role in determining the stone’s worth. Additionally, the lack of standardized certification can make it difficult for investors to assess the true value of their Tanzanite investments.

Key Factors Influencing Tanzanite Value

When considering Tanzanite as an investment, it’s crucial to understand the factors that influence its value:

Color: The most valuable Tanzanite stones are those with a deep, vibrant blue color. Stones with a strong violet or greenish hue are generally less valuable.

Clarity: Like other gemstones, clarity is important in determining Tanzanite’s value. Stones with fewer inclusions and imperfections are more valuable.

Cut: The quality of the cut can greatly impact a Tanzanite stone’s brilliance and overall appeal. Well-cut stones are more desirable and thus command higher prices.

Carat Weight: Larger Tanzanite stones are rarer and typically more valuable. However, the overall quality of the stone is still the primary determinant of value.

Case Studies and Historical Performance

Early Years and Market Introduction

When Tanzanite was first introduced to the market in the late 1960s, it was relatively inexpensive due to its novelty and the limited awareness among consumers. Tiffany & Co.’s marketing efforts in the 1970s helped to increase its visibility, and prices began to rise. Early investors who recognized Tanzanite’s potential were able to purchase high-quality stones at relatively low prices.

1990s Boom and Subsequent Fluctuations

The 1990s saw a significant boom in Tanzanite prices, driven by increased demand and heightened marketing efforts. During this period, the prices of top-quality Tanzanite reached new heights. However, this boom was followed by fluctuations due to economic downturns and market corrections. Despite these fluctuations, the long-term trend has been an overall increase in value.

Recent Trends

In recent years, the Tanzanite market has continued to show strength, with prices for high-quality stones remaining robust. The controlled supply and increasing regulatory oversight by the Tanzanian government have contributed to a steady appreciation in Tanzanite prices. Investors who entered the market in the early 2000s have seen considerable returns on their investments.

Practical Tips for Tanzanite Investors

Research and Education

Before investing in Tanzanite, it’s essential to educate yourself about the gemstone market. Understanding the factors that influence Tanzanite’s value, such as color, clarity, cut, and carat weight, will help you make informed investment decisions. Resources such as gemological institutes, industry publications, and expert consultations can provide valuable insights.

Buying from Reputable Sources

To ensure you are purchasing high-quality Tanzanite, buy from reputable dealers and jewelers. Look for sellers who provide detailed information about the gemstone’s origin, quality, and certification. Avoid purchasing Tanzanite from unverified sources, as the risk of acquiring synthetic or treated stones is higher.


When buying Tanzanite, always seek stones that come with a reputable certification. Certificates from recognized gemological laboratories, such as the Gemological Institute of America (GIA) or the American Gemological Laboratories (AGL), provide an independent assessment of the stone’s quality. Certification can add to the stone’s resale value and provide assurance of its authenticity.

Long-term Perspective

Investing in Tanzanite should be viewed as a long-term commitment. The gemstone market can be volatile in the short term, but Tanzanite’s rarity and increasing demand suggest potential for long-term appreciation. Be prepared to hold onto your investment for several years to realize significant returns.


Given the value and rarity of Tanzanite, it’s prudent to insure your investment. Jewelry insurance policies can protect against loss, theft, or damage, providing peace of mind for investors.


Investing in Tanzanite can be a rewarding venture for those who appreciate the gemstone’s beauty and rarity. Its limited supply and increasing demand make it a compelling option for diversification within an investment portfolio. However, like any investment, it comes with risks, including market volatility and liquidity challenges. By conducting thorough research, buying from reputable sources, and maintaining a long-term perspective, investors can potentially reap significant rewards from this exquisite gemstone.

While Tanzanite may not be as widely recognized as diamonds or sapphires, its unique allure and investment potential make it a gem worth considering. As with any investment, due diligence and a well-informed strategy are key to success. Whether you are a seasoned investor or a newcomer to the world of gemstones, Tanzanite offers an intriguing opportunity to own a piece of nature’s rare beauty while potentially growing your wealth.
