Waterproof Ancient Marine Fossil Necklaces – Ancient Fossils Built to Last
Own a genuine piece of the ocean! This authentic, ancient marine fossil necklace features a real, ancient Shark Tooth Fossil (2–23 million years old) ethically sourced by scuba diving off Florida's coast. Styled after the laid-back, salt-worn look made famous on the Outer Banks — think worn leather cord, weathered fossil pendant, effortless beach style — this necklace is perfect for surfers, swimmers, and anyone chasing that easy coastal look. Designed to be waterproof, durable, and stunningly unique.
Each fossil is matched to your cord length: shorter cords come with smaller ones, and longer cords feature larger ones. Prefer a specific size or color? Leave a note with your order number in the chat box (bottom right), and we'll do our best to customize it for you.
