Specimen of “cactus” quartz (also known as “spirit quartz”) in a light gray color. In this type of quartz, the central prismatic crystals are overgrown by smaller crystals, giving it the appearance of a cactus with spines. An orange hue is visible on parts of the specimen due to the presence of iron oxides. The bottom of the piece is sawn, and it stands as shown.
