Amethyst Geodes are formed millions of years ago in hot lava as gas pockets, fluid silica then penetrated inside, together with combination of iron particles it creates the purple tone. When all the compositions cool off, it produces the quartz crystal inside.
Chakra placement is in the Crown Chakra. Metaphysically the benefit of this stone has been known to give energies for Power, Healing.
This piece is just so beautiful. Would look great anywhere as a stand out piece. The Amethyst is super sparkly with beautiful points in the centre and lovely banding around the outside.
