FADEN QUARTZ

A simply magnificent cluster of quartz crystals from the province of Balochistan, Pakistan. A tabular faden crystal is surrounded by more sharp crystals jutting out in all directions. Many of these are grouped together symmetrically and at one point they make a clearly visible "keyhole" made by a chain of quartz. Just about all of the crystals are in perfect condition. There's a contact point on one of the larger crystals, yet it can easily be hidden without sacrificing any of the aesthetic value. On one side is a patch of chlorite, furthering the beauty found in this fine piece. It's incredible that such a large specimen was able to be extracted without any further damage!

Faden quartz formation occurs within alpine-type fissures, characterized by distinctive white central growth bands ("faden") within clear prismatic crystals. The formation mechanism involved sequential crystal growth during tectonic activity, where continuous separation of crystal fragments during deformation resulted in the characteristic central thread-like inclusion patterns. These specimens demonstrate progressive crystallization under dynamic conditions during the Himalayan orogeny, with the white bands marking successive stages of fissure opening. The crystals exhibit remarkable development of parallel growth features and distinctive internal structures.
