Yes, I am referring to *that* Goodnight Moon! Since it was my children's favorite bedtime story, I still know most of it by heart ~ and I'll bet many of you do too! The pendant is 3 3/4 inches across and is accented by vintage aurora borealis crystals, Bali sterling silver, and assorted glass beads. The gorgeous hook-style clasp allows the piece to adjust from 20 to 22 inches. Goodnight Moon is a one-of-a-kind original.
