Ethical tanzanite jewellery is not a label you can see on the stone. You find it by asking the right questions.
Tanzanite is one of the rarest gemstones on Earth, mined in a single small area of northern Tanzania. That rarity makes it precious. It also makes it easy for the people who mine and craft it to disappear from the story. When I built the Tanzanite Solstice Edition at Oriaku Studio, I asked myself the same questions I now invite you to ask any jewelry brand. Here they are, with my own answers.
1. Where exactly does the tanzanite come from?
Every genuine tanzanite comes from Tanzania, so "from Tanzania" says very little. Ask how the brand sourced it and through whom. For our collection, I worked with the Tanzania Gemmological Centre, under the Ministry of Minerals, so each stone came through an official, traceable channel.
2. Who mined it?
Behind every African gemstone are miners whose names rarely reach the buyer. In March 2026, I went to the mines myself. I did not go underground; I waited above for the workers to come back up. Seeing their faces changed how I think about the word "luxury."
3. Who chose the stone?
A brand that never sees its stones cannot vouch for them. I selected each tanzanite for the Solstice Edition by hand, on site, one by one.
4. Where is the jewelry actually made?
This is the question that reveals the most. Many African gemstones leave the continent rough and gain their value elsewhere, through cutting, setting and branding. The Tanzanite Solstice pieces were made in Tanzania, so more of the value created stays where the stone was found.
5. Do the makers share in the profit?
Fair wages matter, but ownership matters more. At Oriaku, we work on a 20% profit-sharing model with our artisan partners. When the brand grows, their share grows with it. Ask any ethical jewelry brand how its makers benefit beyond a single payment.
6. Is the piece made to last?
A stone carried up from the earth should not end up in a drawer after one season. Slow luxury means small batches, careful hands and pieces you keep for years. Every piece in our Tanzanite collection comes with free repair for three years from purchase. You pay only the shipping.
7. Who gets to tell the story?
For too long, the story of Africa's wealth has been told from the shop window, not from the ground. Look for brands that name their sources, show their makers and speak openly about who benefits. That transparency is the real mark of sustainable, ethical jewelry.
Your ethical tanzanite checklist
Before you buy tanzanite jewelry, from us or anyone else, check that the brand can tell you:
- the channel the stone was sourced through
- whether someone from the brand saw the mines and chose the stones
- where the jewelry was made
- how the artisans share in the profit
- how the piece will be cared for and repaired
If a brand cannot answer, that silence is an answer too.
The Tanzanite Solstice Edition is my attempt to answer every one of these questions openly. African gemstones have always been a source of wealth. My hope is that, piece by piece, more of that wealth stays with the people and places it comes from.
