3.7" Sunset Phantom Quartz Crystals - India
This is a stunning sunset phantom quartz crystal cluster collected from the Andhra Parish Mines in Tamil Nadu, India. These crystals have hematite phantoms that give them a nice, purple-red colored point within a glassy quartz point. This phenomena is often called a sunset phantom, an allusion to the purple coloring in contrast with the orange staining of the crystal base, which is attributed to iron oxides.
Silicon Dioxide, also known as SiO2 or Quartz, is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich, hot watery solutions called hydrothermal environments, at temperatures between 100°C and 450°C, and usually under very high pressure. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountains forming, and can be hundreds of millions of years old.
