👽 “Alien Eye” Fluorite: The Elusive Treasure from Erongo, Namibia 👽
The 2007 discovery of Alien Eye Fluorite in Erongo, Namibia remains a standout moment in mineral collecting history. These bi-colored crystals, known for their striking zoning and alien-like appearance, are now considered one of the most desirable fluorite finds of the 21st century.
Only a few elusive pockets were ever uncovered, and to date, their formation has never been replicated. Upon their initial release, demand surged, and the limited quantity was quickly absorbed into collections around the world.
Today, opportunities to acquire these specimens arise almost exclusively through the resale of older collections—such as this exquisite small cabinet piece from the Ex. Pohl-Stroher Collection.
A Legacy of Fluorite Excellence: Dr. Erika Pohl-Stroher
Dr. Erika Pohl-Stroher, a renowned patron of the mineral world, was especially passionate about African localities. Her extensive network of scouts worked tirelessly across multiple continents to secure specimens directly from the source. Thanks to these trusted connections in Namibia, she was able to obtain an impressive suite of Alien Eye fluorites—well before they were known in the broader market.
The specimen featured in this article was acquired from her distinguished collection and is now housed in the Rocksity Vault.
Specimen Overview: Rare Zoning and Crystal Form
This standout fluorite cluster from Erongo showcases several bi-colored fluorite crystals, each measuring up to 2.4 cm across. The crystals display dominant cubic form with subtle octahedral modifications, and range from transparent to translucent with a refined satin luster.
Color zoning is pronounced and beautifully layered:
Bright, almost emerald-green cores
Deep purple-black corners
A final 1–2 mm light green rim surrounding each crystal
The overall effect creates the glowing, eye-like appearance that earned this fluorite its nickname.
The matrix is accented by snow-white albite crystals (to 1 mm) on the underside of the cluster. The specimen remains in excellent condition—a pristine and compelling example of this rare formation.
