This is a hand carved sterling silver Blue fin tuna, made as part of my ocean collection. Having been fished for hundreds of years the blue fin tuna is becoming higher up on the endangered list, and it isn't common knowledge. The tuna being caught is getting smaller and smaller due to younger fish being caught, not allowing them to meet sexual maturity means their species won't be able to sustain this fishing. Any pendant can be made with a smaller or larger chain, please message for details. Thank you.
