Here you have a fantastic Blueberry Quartz Tower. They measure approximately 55mm - 60mm by 20mm - 25mm wide
The photo depicts several towers, but price is for one. The photo is to give idea of natural variation between each obelisk.
Blueberry Quartz is very similar to Cherry Quartz and is a crystal for the New Age
It is a bit of a mystery to what the mineral actually is that is added to the Quartz to give it that electric blue colour but no doubt in time all will be revealed.
I do know that for 2007 this is going to be very popular, it is already much sought after by healers and psychics because of its high vibrational energies.
