This specimen is actually formed not by one but by two gwindel quartz on matrix. While most of the specimens coming from this Pakistanese area are mate or with a poor luster and often damaged, this one is lustrous and damageless. The twist is visible when you look the specimen from the top. The second gwindel is visible at the back of the main one (see picture 3).

Locality : Shalman area, Khyber District, Khyber Pakhtunkhwa Province, Pakistan
