This is a specialist clear quartz called Tibetan Quartz Point or Sichuan with quartz double terminated points. The quartz has enough clarity that you can see inside and it is a double terminator configuration. And there are carbon (or manganese inclusions which raise its vibration. Some minor nicks as all natural crystals have.
Clear quartz itself already helps cleanse and open all chakras to help energy flow around the bodies. And this helps focus, clarity of thought and concentration. Sichuan or Tibetans do this even more powerfully with their higher vibration. Great for shamanic work. I find that those about to go on a new burst of spiritual growth are called to get these, or they have just started that cycle. Read more about the shape too.
This Tibetan quartz Point looks even better in person.
