A stone found in only one place on all of Earth.
Real, unheated tanzanite from the foot of Kilimanjaro. I travel to Tanzania myself, sit with the miners I have known for years, and bring home the pieces that stop me in my tracks.
Every tanzanite on Earth came from a few square miles of Tanzania.
Not a mine on every continent. Not something you stumble on anywhere else. Tanzanite formed once, in the shadow of Kilimanjaro, and nowhere else has ever turned it up. When you hold a piece, you are holding something the planet made in a single corner of a single country.
Tilt it, and it changes before your eyes.
This is the same stone in both photos. Tanzanite is trichroic, which is a friendly way of saying it holds more than one color at once. Turn it toward the light one way and it is deep ocean blue. Turn it again and a rich red rises. Drag the slider and watch it happen. In a heated stone this is mostly cooked away, so seeing it this alive is the mark of a natural, unheated crystal.
Around 99 percent of tanzanite is quietly heated.
Straight out of the ground, most rough tanzanite looks muddy or brownish, so the trade heats it to force a uniform blue. It works. But it costs the stone its magic. Heat flattens that shifting color and erases the red, green, and bronze flashes that make tanzanite feel alive. Everything I sell is unheated. What you see is what the earth made. Nothing added, nothing faked.
Heated
Cooked to a flat, uniform blue. Easier to sell in bulk, but the secondary colors are gone for good. This is most of what you find out there.
Unheated, always
Natural color, straight from the rough. The full trichroic range still lives inside it, just like the stone in the slider above. This is the only kind I bring home.
Small, family run, and honestly a little obsessed.
This started as a passion for collecting more than twenty years ago, and at heart it still is one. My partner Shelby and I run everything ourselves. I fly to Tanzania, buy the best of what comes up in person, and because I skip the middle layers I can offer some of the best pricing in the industry, close to wholesale, on stones I would be proud to keep for myself.
Straight from the source
I buy face to face in Tanzania and support the miners I have worked with for years. No long chain of hands in between.
Unheated and top quality
Every piece is natural, never cooked, chosen for color, clarity, and that living pleochroic flash.
Some of the best pricing in the industry
Near wholesale, because I keep this lean and cut out the markups. Payment plans are welcome on the higher value pieces, just ask.
