Gemstone Skull carving
Gemstone skulls have been popular (and mysterious) for numerous 
cultures for many centuries. The skull holds many different meanings.
Celtic skull symbology include: Time, Power, Creation, 
Initiation, and Concentration. Celtic culture viewed the head or skull to be 
the seat of power. Some texts point to the skull as the house of the soul. 
Archeological findings show us the Celts tossed skulls into sacred wells as offerings.
The skull is universally considered to be a symbol of Death and Mortality. More 
recently the skull has become associated with conquering death and embracing our mortality.
In ancient times for some cultures, the skull represented life. Skulls and skeletons are the main 
symbol of the Mexican holiday, Day of the Dead. The skull and crossbones is a popular symbol 
for both pirates and poison.
Some healers use gemstone skulls to see visions of the past, present and future.
