Collection: Jewelry

Own a piece of prehistoric ocean history with this handcrafted fossilized marine pendant necklace. Crafted from ancient marine fossils (2–23 million years old), ethically sourced through scuba diving and excavation off the coasts of Florida and South Carolina, this durable, waterproof pendant is a unique tribute to the ocean’s past. No living marine life is harmed—our fossils are sustainably hand-collected by SHRKco owner Jeffrey Heim. Since 2019, we’ve passionately refined our wire-wrapping craft to create our finest design yet, built to last for years. Customize your necklace with options like black, gold, or silver wire wrap and multiple chain lengths (S, M, L, XL). SHRKco donates 10% of net profits to shark conservation through partnerships with FinsAttached.org and SavingTheBlue.org. Personalize your order via our chat box for a one-of-a-kind piece!
