Discover the striking beauty of this handcrafted necklace, featuring a rare fossilized marine pendant from the Snaggletooth shark (Hemipristis serra), aged 2–23 million years. Ethically sourced through scuba diving and excavation in Florida’s prehistoric coastal waters by SHRKco owner Jeffrey Heim, each pendant is collected without harm to living marine life. Lower-position fossils boast a dagger-like shape, while upper-position fossils, available in our shop, feature wider, serrated designs. Crafted with tightly wrapped, tarnish-resistant wire and durable stainless steel components, this waterproof necklace is built to last with exceptional craftsmanship. Necklace length refers to the full, outstretched cord, customizable to your preference. SHRKco donates a percentage of profits to FinsAttached.org and SavingTheBlue.org, supporting their scientist-led efforts to protect marine species worldwide. Wear this unique piece to share Jeffrey’s passion for ancient oceans and champion conservation! For customizations, message our live chat with your order number.
