This Sapphire is a naturally blue, naturally shaped, 6 sided cylinder of a crystal that we had custom set in India. Chain not included, but we do sell them. We consider Sapphire to be a kind of Voice stone – with a downward movement, energetically – due to its own heavy weight (and being related to its red version, Ruby, which is the ultimate Grounding Root stone). So Sapphire is kind of grounding the higher Energy Zones. Length: 3cm; Width: 1.3cm; Height: 1cm Weight: 31ct Origin: Central Asia, India
