Phantom Selenite Specimen from La Platosa Mine Mexico

Phantom Selenite Specimen from La Platosa Mine Mexico is a premier geological specimen highly sought after for its distinctive internal growth markers. This variety of gypsum, specifically the selenite variety, originates from the La Platosa Mine in Bermejillo, Durango. This locality is scientifically significant as a high-grade carbonate replacement deposit (CRD), where hydrothermal activity has allowed for the development of exceptional crystal structures. The defining characteristic of this material is the presence of "phantoms"—ghostly internal outlines caused by pauses in the crystal's growth cycle. During these pauses, secondary minerals or organic matter settle on the faces of the crystal before growth resumes, permanently trapping a visual record of the crystal’s earlier developmental stage. 

This cleaved Phantom Selenite from La Platosa Mine Mexico specimen exhibits the classic monoclinic crystal system with a vitreous to pearly luster. The phantoms within this specific locality often appear as dark, smoky, or brownish-black shadows, frequently attributed to the inclusion of organic materials or fine-grained manganese and iron oxides. These internal structures are often highlighted by the water-clear transparency of the host selenite. Mineralogically, the crystals possess a Mohs hardness of 2, making them delicate and requiring careful handling. Unlike specimens from other regions, the La Platosa finds are noted for their sharp, well-defined phantom boundaries and the structural integrity of the blades.
