Shiva Eye Shell Pocket Heart

I bought these to make pendants out of but while staring at them I thought that these would serve just as well as a pocket healing crystal, approximatly 45mm wide by 40mm and 15mm deep.
Also known as “Pacific Cats Eye” the Shiva Eye Shell comes from a specific type of Snail found off the coast of Thailand.  It is the “trap door”  or Operculum of the shell the snail organism goes in and out of specifically.  Named after the Hindu God, Shiva, the shell represents the Third Eye found in many depictions of the God.  Folklore suggests Shiva Eye Shells are “Mermaids’ Money” and good luck to travelers and fishermen.
The Shiva Eye shell has a number of meanings associated with it.  Eyes in general are a symbol of protection as to ward off the “Evil Eye”.  Coming from the sea, this shell has ocean-like soothing, comforting and serene vibes and will bring peace of mind and relaxation.  The Spiral shape has great significance as well, representing the Golden Ratio.  
Shiva's eye is known to protect wearers from all forms of negativity help to concentrate the mind, and aid in decision-making. The stone is believed to increase stamina and self-confidence and have a cooling effect on the body. Shiva's eye affects the point where Shiva and Shakti become one.
