This is a Hashupi quartz crystal of the highest quality.

This  crystal has a Tabular shape with proeminent growth lines in its body. It  also has rainbows on the tip and siderite inclusions.

Hashupi  quartz crystals of high quality are a very rare type of Himalayan  crystals, the higher the quality the higher the difficulty to get them,  not only because of climate conditions and high altitudes, that makes  miners only extract them for a few months a year but also because  crystals of such high quality  have been very hard to find in the mines.
Optical  crystals are crystals that are water clear, we can easily see through  them and are also crystals that have reached a very high state of  evolution.

This crystal comes from Hashupi mine,  in  Shigar Valley, Shigar District, Gilgit-Baltistan, Pakistan.
