Hey my crabby babies 🦀 I made this pendant for all the Cancers out there. You have the option of sterling silver or bronze. The chain for bronze is gold fill. Thinking you want your birthstone on it too🤔. I have that covered, let me know at checkout the birthstone month and where you’d like it placed. There’s a sweet little crab that lives with the clasp. The chain is 16 inches long with 2 inch extension. Comes with lobster claw clasp not safety pin. 2 weeks to ship
