Hamsa Hands are a big favourite of mine when it comes to symbols and spiritual tools carves in crystal. Hamsa literally translates to 'five's in reference to the number of digits on one hand. Each digit represents a different blessings, health, wealth, fertility, joy and success.
You will also the the eye symbol in the center of these hands as they are an incredible powerful protection symbol warding of negativity and psychic attack.
The symbol as a whole encompasses energies of happiness, health, protection and blessings.
