A little over six years ago, I had the chance to visit Tanzania and Kenya. This summer, I got the chance to go back, as a guest of Gem Legacy.

I know how lucky one trip makes me. Two is a gift I wouldn’t have expected, but it provided me with another amazing opportunity to go to gem-sourcing areas and see how much has changed since I last visited in January 2016 with a group organized by Roger Dery.

It’s such an important region for our industry, and it’s an interesting time for both countries in regard to their gem trades.

In that vein, I wanted to share some of what I observed on my second trip to East Africa.

Tanzania continues its efforts toward value addition
When I traveled to Tanzania in 2016, there was not yet a wall around the tanzanite mining area; former Tanzanian President John Magufuli would construct it a year later to regulate activity. 

The area is comprised of four mining blocks—we heard an estimate of 400 mines among them—one of which is where our group went for a visit to the Merisheki mine, owned by Roger’s longtime friend and miner Sune Merisheki.

Entering the wall required a lot of planning and preparation for our hosts in terms of getting our information, visa, and passports to the government ahead of time to get permission for our visit.

It required a police escort and, on the way out, a pat down from security to prevent smuggling.

It was well worth it for the chance to go behind the wall to not only see the scope of mining activity but also for the opportunity to enter one of the mines—Sune was nice enough to let us go underground. 

Led by his son, Bjorn Merisheki, and with a lot of help from their mine workers, we went down more than 300 feet, ending at a spot where they hit a pocket so they could show us the vein they were following and point out the mineral indicators.

With steep steps and just headlamp lighting, it was a fairly grueling trip down and back, but one I would do again and again because nothing beats that firsthand experience to help understand the science behind mining and, more importantly, see what the miners endure to recover gemstones.

When it comes to tanzanite, all buying and cutting activity has to be done within Merelani town, and finds have long had to be registered with government officials.

The wall might represent the most concrete example of Tanzania’s move toward beneficiation, but it’s hardly the only one.

In another big move in 2018, the Tanzanian government put a ban on the export of all rough stones from the country to try get the cutting and polishing done in-country before being sold elsewhere.

The ban brought much of the country’s market to a temporary halt as it wasn’t equipped to suddenly cut that much material.

Today, Tanzania bans the export of more than a half-dozen gemstones when they weigh more than 2 grams (10 carats) in rough form: ruby, sapphire, emerald, garnet, spinel, tanzanite, and alexandrite.

Gemstone trading activity also has been moved to one area in Arusha.

Given the country’s current importance in the colored stone trade, it will be interesting for everyone involved to watch what other moves the Tanzanian government makes.

Kenya’s drawing inspiration from its neighbor
It seems Kenya has taken notice of Tanzania’s efforts to keep its mineral wealth in-country.

While in Voi, Kenya, I had the chance to go to the new Voi Gemstone Center, created for the purpose of value addition and offering gemstone identification services, faceting equipment, places for buying, selling, and trade fairs, training for the industry, and even help with exporting stones.

Taita-Taveta is the most important area for gem mining and trading in Kenya, with about 5,000 mines in the area, according to one official.

Bjorn and his wife, Rachel Merisheki, were meeting with Edward Omito from the Ministry of Mining and were nice enough to let me listen in on their chat about the center and the area’s progress and what work still needs to be done.

Edward seemed genuinely excited for the potential of the center, which was created to make business easier for members of the gem trade in Taita-Taveta, but he noted at the time of my visit  in late July they were still waiting for the president to commission it for activity to really get going.

Indeed, while he was nice enough to give me a tour of the space, it was pretty empty when we walked around, with no booths for trading set up and only a few people using the equipment.

Interestingly, he said they got the idea for the center from Tanzania and how it was working to create a process in-country for tanzanite.

They want to eventually expand to have open-air markets in Voi, he added, potentially inviting buyers from other countries to visit and do business.

Edward did note when we were there, though, that the center has been a political project of the president. At the time of our visit, we were just ahead of an election, and he seemed very aware that the center’s future was dependent on the election results.

William Ruto, formerly Kenya’s deputy president, was declared the new president in August.

The Voi center seems like it could make a difference in the Kenyan market, so let’s hope it doesn’t lose steam before it’s had the chance to get off the ground.

Students at Kitarini performed traditional Maasai song and dance for us in Tanzania.

How gemstone mining is changing a lifestyle
One of my favorite parts of both trips was a visit to the Kitarini Primary School for children of Maasai miners, not only for the chance it provided to meet and interact with its students but also because it’s an interesting look at a changing lifestyle spurred by gemstone mining.

The school has grown drastically since I was there in 2016, thanks to the hard work of the Merisheki family, the Dery family, Gem Legacy’s efforts to raise money for various initiatives, many other members of the trade, and of course the school’s amazing staff doing everything they can to meet the challenges that arise for their students.  

There were several new buildings when I went back this time, and the student body had more than doubled to nearly 950 students. 

The school’s focus now is on building additional teacher housing so they can attract and hire more faculty and, eventually, adding more classrooms. 

Our group had some incredible experiences while we were there, participating in an activity day that had us spending an entire school day with the children and getting to see several student performances of traditional Maasai dances. 

The school is in the Longido district, north of Arusha, an area rich with ruby-in zoisite. (The area also produces some gem-quality rubies but not in large numbers.)  

It’s also located firmly in Maasailand, which presents its own obstacles for those trying to build the school—the Maasai are semi-nomadic and pastoral, meaning they live by herding cattle and goats. This includes herding done by their kids, leaving little time for traditional schooling. 

For Kitarini, this has meant issues getting students to come back regularly, especially when it requires long walks to and from or during the lunch hour prior to setting up a lunch program.  

But this is also what makes their success so amazing—a group of people who traditionally have moved around are now staying still for the chance to find gemstones. 

There were several moms on the school board—also part of the Maasai tribe—who spoke with us about wanting to get involved as they realized how important it was for their kids. 

What an interesting thing, to see gemstone mining influencing such a thing.   


Miner challenges there are similar across the board
We visited six mines during the trip, all but one in Kenya, and what struck me was when asked what they most struggled with at their mines, the miners all gave same answers: a lack of water, food, and/or equipment.

For many of them, the rainy season also brought issues of flooding and how to redirect the rainwater away from their mines.

You really only need to see one mine in the bush of Africa to understand how hard their work is and what they deal with for just the hope of finding a stone.

There were also several mentions about one ongoing issue affecting the mining world: the need for more education about the gemstones being mined and their value.

GIA has tried to address this issue, for example, with its creation and distribution of a gem guide for artisanal miners, and it’s something Edward Omito also said he hopes to help alleviate with the Voi center when it opens.

Many of the experiences we had on our trip kept bringing a crucial part of the conversation around responsible sourcing and transparency to my mind—the importance of keeping a local perspective, going directly to the miners and traders and asking what is needed, rather than assuming or trying to solve issues that aren’t there. 

If the importance of providing such help to those at the first step of our supply chain isn’t immediately obvious, you’d only need to visit one mine for that clarity as well—each and every person we met had such immense pride in the work they were doing.

The miners couldn’t wait to share their stories with us and show us their mines.

In so many cases, I swear they would’ve happily sat there the whole day talking about mining or going inside the mine with us, showing us how far they’ve gotten and the veins they were now following.

I still can’t believe I got the chance to have such an adventure a second time.

It’s a trip I wish everyone in the industry, regardless of their role in the trade, would get the chance to take because, cliché as it may sound, it’s truly life-changing and eye-opening.

Now that there’s so much of a focus on responsible sourcing at each point in the supply chain, it also makes me hopeful for the direction in which we can all head together.
