I was able to make two Rainbow Fluorite pendulums on the Fall Equinox, and this one is the most vividly banded. The plumb bead is a pretty oval about 7x15mm.
I always ritually craft my pendulums on a Monday or Wednesday when the Moon is Half Full, and this one is also from a batch that I made on the Autumnal Equinox, Sept 23, 2020, for even more balance.
