Quartz, Quartz after Fluorite

This specimen features quartz epimorphs that have formed after what is believed to have been fluorite, displaying softly-defined dodecahedral forms. The epimorphs are adhered to a single quartz prism with a very sharp tip and an almost triangular prism. The quartz epimorph formations are hollow, as evident from the incomplete crystals, which offer a fascinating glimpse into the mineral’s unique growth process.

The specimen was collected during a trip to a locality known as Gringo Gulch, near Patagonia, Arizona. This area is known for its distinctive mineral occurrences, particularly for amethyst crystals and now for these intriguing quartz epimorphs.
