Foitite specimen with Fluorite on Feldspar - Erongo Mountains, Namibia

I’m really glad I get to show you this piece of Foitite specimen with Fluorite From Erongo Mountains in Namibia because the Erongo Mountains are legendary among collectors for a reason. This Foitite specimen is a fantastic example of the complex chemistry that happens within those famous granite pegmatite pockets. Most people see a dark tourmaline and immediately assume it is Schorl, but Foitite is actually a much more specialized, alkali-deficient member of the tourmaline group. It is the kind of subtle mineralogical distinction that really appeals to those of us who enjoy the specific chemistry of our specimens as much as their shelf appeal. Geologically, these form in miarolitic cavities—essentially open pockets in the cooling rock that allow crystals the space to grow with sharp terminations and clean faces. This Foitite isn't just a rock; it’s a tiny snapshot of a very specific high-heat environment from millions of years ago. It’s a completely natural, unpolished specimen that pe
