Clear quartz with hematite. Sunset phantom quartz from the Kakamunurle Mine, India. Sunset phantom quartz is formed when a clear quartz crystal grows with inclusions of hematite, creating a purple-red "phantom" effect within the crystal, typically against a base with a yellowish or orange hue due to iron oxide staining, resembling the colors of a sunset; this happens during the crystal's growth process where the mineral deposition is interrupted and then continues, layering the inclusions within the quartz.
