I came across a similar design to this one on a pendant and it reminded me of a chakra - a "wheel", a sort of energy concentration. I thought how neat it would look incorporating a geode in place of the sun in the center. The milky geode has a gentle and soothing effect that radiates outward.
I included in the design a clear quartz crystal, since clear or white stones are known to bring clarity and purity to one's surroundings.
The single quartz crystal
helps to bring balance and the point facing downward has a grounding
