kindly sent me an ohm charm on the day of the solstice. It's more readable as ohm from the other side but I think this view is more interesting.
It is nestled in hematite, black cat's eye & little metal beads. The string is also metal & is held together by a lobster clasp & a knot on a bight. I had to do the knot with tweezers...
It's strung close to the throat so the beads don't move too much. It's cold. not really a winter necklace. But I think it will hold up well in the summer even when I am climbing.
