Chalcedony and Fluorite in matrix

Chalcedony restores calmness and balance, and helps one to look toward the future with optimism and enthusiasm. It enhances creativity and imagination, and opens the mind to assimilate new ideas.
 
Fluorite cleanses the aura. It can be used to protect against electromagnetic stress, such as those given off by mobiles or computers.
Fluorite helps in organising and processing information and is handy to keep at your work desk as it helps you learn new information and increases concentration.
