I am thinking about getting either an obsidian sphere, pyramid, or beaded necklace to better help ground me and protect against other peoples negative vibes. I have several questions though relating to the power of the crystals in each of these options.
Assume the obsidian in both cases is of equal quality and equal combined volume. What would be more powerful: a bunch of obsidian crystals that has a combined volume of 40 cubic mm (say a beaded necklace,) or one single obsidian crystal that has a volume of 40 cubic mm?
Also, I know the shape of a crystal might make a difference as well. What would be more powerful: an obsidian pyramid, an obsidian sphere, or is the shape not so important?
Also if a pyramid is more powerful than a sphere, then just how much more powerful is it?
I know a lot of these questions might be hard to answer, but I am sure I came to the right place
