3.5" Faden Quartz Crystal Cluster - Pakistan
This amazing faden quartz crystal cluster contains liquid and gas scars throughout the specimen, leaving the quartz with thread like inclusions. This multi-terminated quartz is fairly transparent and the terminations are in great condition.
Faden quartz is typically found in mountainous regions, with Quetta and Northern Pakistan being the most well known deposits of these beautiful specimens. These quartz formations occurs between cracks in a host rock. The cracks in the rock expand with the crystals, occasionally causing ruptures within the crystal, from pressure. This causes the healing process to begin, giving rise to the branching off of parallel faden quartz crystals, which can be seen in the majority of our listed specimens.
Silicon Dioxide, also know 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.
