Fluorite with Quartz (Eisenkiesel) – Globenstein, Erzgebirgskreis, Saxony, Germany

Green octahedral fluorite with secondary purple cubic fluorite habit and hematite-stained quartz.

This striking miniature specimen presents a fun example of the mineralogical diversity characteristic of the Globenstein locality, part of the historic Ore Mountains (Erzgebirge) mining region in Saxony. The centerpiece is a sharp, translucent green fluorite crystal with well-defined octahedral habit, lightly frosted with a matte surface that enhances its geometric form. At certain angles, the green hue reveals faint phantoms and zoning under bright light—subtle, but perceptible.

What makes this piece especially compelling is the presence of a second-generation fluorite habit: small, intergrown purple cubic crystals perched on and around the octahedron. These appear to have developed in a later stage of mineralization, creating a fascinating contrast in both habit and hue.

Scattered around and partially enclosing the fluorites is Eisenkiesel quartz—hematite-stained quartz with an appealing rusty-orange to peachy coloration. These microcrystalline quartz aggregates form delicate sprays and botryoidal coatings, lending a fine textural counterpoint to the bold geometry of the fluorites.

There is also a light dusting of goethite or limonite across some surfaces, hinting at the oxidizing conditions during later-stage hydrothermal activity. The base rock is a compact, fine-grained matrix that provides a sturdy foundation for display.

Overall, this is a well-balanced and aesthetic piece that highlights the classic paragenesis of Saxon fluorite veins—elegant, mineralogically diverse, and locally significant.
