I always feel a bit humbled when working with fossils such as these Ammonite. Something about holding one in my hand and realizing how insignificant we are against the march of time.
Two Ammonite necklaces up for grabs. Pretty much identical but one "swirls" to the right and the other swirls to the left!! The back side is just as pretty. Both on over the head length of deerskin lace with vintage  filigree tube that acts like a slide to adjust to whatever length you want.
