Que Sera

Que Sera 
The stone of ultimate power
A new age stone possessing an unusual and high vibrational frequency
Helps to better understand our emotions
Encourages us to let loose and live life to the fullest with optimism for whatever comes along the way
An all around healer and re-enegizer 
An excellent shield against Wi-Fi emanations or other electromagnetic pollutants and geopathogens
Balances your meridians and recharges your energy
Helps you find constructive solutions to problems and be confident on your actions
Brings strong energy and spiritual light into the body

I have also seen these referred to as Galaxy Rhyolite, which is appropriate since they are a part of the Rhyolite Family.  
 
These are priced by weight and not necessarily by size.
