Beautiful handmade gold color anchor nautical necklace. There is no actual bone used in this piece, it does have a bone tip look to it on the ends. This necklace was inspired by Once Upon A time, and the Percy Jackson Series. It has a lost at the bottom of the ocean look to it from a time forgotten. Beautiful piece makes a great gift or for everyday wear. Great piece for any event, wedding, cosplay, costume, or renaissance play. Necklace length measures appropriately between 14-16 inches with extender. Hypo allergenic. Made for those with metal allergies. Safe for giving when you don't really know if they have a metal allergy. I hope you'll like these as much as I love them. If you have any questions feel free to ask. Thanks for looking!
