This is a gorgeous piece with a lot of symbolism.  The etched portion of the pendant depicts a dog.  Celtic hounds symbolize hunting, healing, and the Otherworld in Celtic legends. Hounds were the traditional guardian animals of roads and crossways and are believed to protect and guide lost souls in the Otherworld.  The stone is Chrysocolla Metal Matrix.  It is set in fine silver. The accent metal pieces are etched and stamped brass and attached via cold connection brass screws. This pendant is suspended on a Sterling Silver Viking knit chain.  
Chrysocolla is a stone of empowerment of the feminine energies, teaching that genuine power is best expressed through gentleness. It is a stone of the Goddess, and those who resonate with it will likely feel her ancient and enduring energies rising within themselves. 
It is the stone of forgiveness, peace, and the strengthening of emotional bonds. It encourages compassion, and helps us recover our natural spontaneity.
