Tanzanite Background Story and Market Report

Published: March 2020

JTV would like to update its customers about new developments regarding the closure of the world's biggest miner and supplier of Tanzanite by the Tanzanian government. Due to trade restrictions, tanzanite can only be bought and sold at government-run trading hubs. Only two main trading hubs are open and an estimated less than 22,000 carats of all Tanzanian mined gemstones have been processed through these trading hubs for worldwide distribution.

The Tanzanian government has also placed restrictions on smaller scale tanzanite mining operations. Tanzanite continues to be in high demand and, unfortunately, due to these recent developments, there may be an increase in cost and a reduction in available tanzanite for sale.

JTV continues to closely monitor the unstable situation in Tanzania and the ongoing issues between the government of Tanzania and miners. At this time, JTV has learned that the government of Tanzania has announced confiscation of any and all tanzanite, concealed or unreported, held by miners.  This action follows reports that dealers are secretly selling tanzanite outside the country without the involvement of government officials. 

The government of Tanzania has taken several steps to reform the mining industry, including construction of a wall around tanzanite mines along with installation of security cameras and other electronic devices to monitor the movement of this high-profile gemstone.  These reforms have been established with the following goals:

  • Control of tanzanite at all levels
  • Enable the government to collect its “fair share” of revenues
  • Reduce smuggling and tax evasion
  • Greater opportunities for artisanal miners

There are still many concerns and uncertainty about the tanzanite industry and the unrest in the mining sector between the government of Tanzania and the miners of large and small artisanal mines.  It is unknown how the actions from the government of Tanzania will impact the flow of tanzanite out of this country and the cost of this treasured gemstone.  Tanzanite continues to be one of the most popular gemstones in the world, however there may be changes and fluctuations to the available supply. JTV will continue to watch this ongoing situation and provide the latest news and updates for our customers.  Please see the following articles for more information about the history of the tanzanite market.

JTV would like to notify its customers that the world's biggest miner and supplier of tanzanite has been ordered to shut down due to ongoing issues with the government of Tanzania. JTV is unsure at this time of how long the closure will be in effect or how long it will take to resolve the dispute. Tanzanite is still being mined in other small-scale artisanal operations, but these mines will have lower production quantities of the gemstone.  Tanzanite continues to be in high demand, however due to these recent developments, there may be a reduction in available tanzanite for sale.

To understand the tanzanite market, one must consider both the unique characteristics of tanzanite and its history prior to 2010. A combination of four key factors has set the stage for an industry that has experienced, and continues to experience, a great deal of fluctuation.

The four key factors are:

1. Tanzanite is a young gemstone in comparison to others in the market.
2. Tanzanite is found and mined in only one location.
3. Tanzanian government mismanaged the mines in early years and stunted growth.
4. Advanced and ‘westernized’ mining operations have changed the tanzanite business.

A Very Young Gemstone

Many of today’s most popular gemstones were discovered thousands of years ago. Evidence has been uncovered in artifacts and old transcripts such as the Bible. Tanzanite, on the other hand, was only discovered in 1967. Comparatively, its existence to man has been a mere blip on the timeline. In the case of ancient gems, the market has long been established, mines are claimed, popularity already exists, etc. However, the scenario is different for tanzanite, a stone that has seen mainstream awareness for less than 20 years.

Found in Only One Location

The world’s only known source of tanzanite was discovered in the Simanjiro district of Tanzania. Geologists say the chemical environment required to form the beautiful blue gem is so unique that chances of finding the same conditions elsewhere are next to impossible. Therefore, experts estimate the probability of discovering another tanzanite deposit is less than one in a million.

Being found in only one place leads to a couple of problems regarding stability. The quality and quantity of gem deposits will vary as miners slowly dig through the earth’s core. Therefore, the production of sellable rough is not consistent at all depths and no one can predict this variation. Additionally, a natural resource from a single location cannot last forever. Eventually, if other deposits are not located and that seems most likely, it will dry up.

Early Mishandling by Government

Tanzania is a third-world country that only gained independence in 1964. Since that time, it has experienced a great deal of hardship. In 1971, a young and inexperienced government began to realize the monetary potential of tanzanite, so it took control and nationalized the mines. However, necessary structure was not in place, and quality of mined material diminished. Around that time, tanzanite had just reached the US, resulting in a large and enthusiastic push by famous jeweler Tiffany’s & Co. The erratic changes in supply caused problems, though, which eventually led Tiffany’s to stop promotion. In 1972, the Tanzanian government formed STAMICO (State Mining Corporation) in an attempt to fix issues and capitalize on tanzanite.

That same year, the country was attacked by Uganda, which led to a two-year war. STAMICO’s efforts to begin full-scale mining did not materialize, and while the tanzanite market remained alive, it was quite volatile. Then in 1990, officials split the area into four sections: Blocks A, B, C and D. Blocks A and C were awarded to large-scale operators, while Blocks B and D were reserved for local independent miners. At that time, some organization entered the industry, and it was able to slowly move back into US markets.

Modern Operations Introduce Global Marketing

Once advanced mining companies began to operate in Blocks A and C, the tanzanite market was forever changed. Their business skills were something small-scale miners and Maasai simply did not have. A level of sophistication was introduced to the industry. These businesses had the resources and tools to make tanzanite an international success.

Review of Tanzanite Supply Chain

Before moving on to our market report, the supply chain is another important piece to review. Tanzanite is mined approximately two hours outside of Arusha, the Tanzanian capital. As mentioned before, the area has been segmented into four sections: Blocks A, B, C and D. From the mines, rough material is sold at buying offices in Arusha and in the outer villages of native Maasai. Next, it travels to cutting facilities, almost exclusively located in India. The finished gems are then sold to jewelry manufacturers and other retailers such as JTV. To truly investigate market conditions, JTV started with the first two links of this supply chain. Our team spent time both visiting the mines and meeting with local suppliers.

Today’s Tanzanite: A Market Report

The tanzanite market is currently in a state of change. From 2004 to 2008, the industry experienced a period of consistent growth. Demand was increasing at a healthy rate, and mine owners were finding a surplus of material in all quality grades. Then in 2008, the United States’ economy began to crumble. This had a great impact on the market because, historically, an estimated 70% of tanzanite was consumed by the US alone. What resulted was a dramatic drop in price per carat during 2009. However, as people across America curbed spending on luxury items, the situation was a little different for tanzanite. The lower prices were so appealing, gem enthusiasts took advantage and buying continued at a fairly steady rate.

What is happening to the market in 2010 comes down to a fundamental principle of economics – the law of supply and demand. Tanzanite is still being mined, but prospectors state production rates have declined. This is especially true for top grades and large carat sizes. Reduction percentages varied among the mining operations. Block C recently reported a 14% decrease for FY 2009, while some of the local Maasai in Block D claimed losses above 50%.

At the same time, global demand is increasing. As mentioned earlier, the US has traditionally consumed a majority of tanzanite. However, popularity is quickly growing in the international arena. The European and Caribbean markets have gradually been increasing over several years, but the big change is coming from Asia. Now, China and Hong Kong are buying tanzanite, and it has greatly changed the dynamics. When demand increases as supply decreases, it ultimately has an effect on price. In the last 15 months, JTV has seen the price of top-grade material rise 40%. Additionally, after the 2010 Hong Kong show, an executive from Block C reported a general increase of 16.5% per carat and a top-grade increase of 29% since November 2009.

End Note: While the global supply is in a decline for the time being, it is still strong enough to support the industry. Additionally, JTV is happy to report we have solidified relationships with the top three tanzanite vendors. In totality, this trio controls over 70% of the supply. Therefore, we feel confident we can continuously source tanzanite for the foreseeable future and offer it at the most competitive prices on the market.
