Tree of Life Necklace with Gemstones

This is one of my larger tree of life necklaces. The tree pendant measures 3.5cm in diameter.

The pendant is topped with the following gemstones: amethyst, citrine, aventurine. black onyx, jasper and yellow jade.

The classic ball chain measures 50cm, 20" in length.

All metal is silver finished.

'Wikipedia' offers this information about the 'tree of life':

"The concept of a many-branched tree illustrating the idea that all life on earth is related has been used in science, religion, philosophy, mythology and other areas. A tree of life is variously,

a) a mystical concept alluding to the interconnectedness of all life on our planet,

b) a metaphor for common descent in the evolutionary sense, and

c) a motif in various world theologies, mythologies and philosophies."
