Large Quartz Crystal Cluster. 2.6 kg. 17 cm x 12 cm x 12 cm

Beautiful Quartz Crystal Cluster used by myself over a 19 year period in Reiki,/ Shamballa,/ Angelic ReiKi workshops. Also during Yoga Tai Chi and Qi Gong sessions.
It has been a much loved piece but due to my retirement, it has become surplus to requirements
Not sure of the origin, it was a gift to me from a student.
