This little acorn is a reminder that we all start out small but are full of the potential of the strong and enduring oak. A symbol of wisdom, growth and strength. I found a tiny acorn at The University of Limerick after a storm, cast it in silver and added a layer of 18ct hard gold plating. Gold plated sterling silver acorn on an 18 inch chain gold filled chain. Solid 9ct yellow gold acorn on an 18 inch solid gold chain.
