I'll add: The pin is a Girls Scout Pin known as The World Trefoil Pin
Every part of the World Trefoil pin, a unifying symbol of WAGGGS, has a meaning:
The golden trefoil on a bright blue background represents the sun shining over all the children of the world
The three leaves represent the threefold Promise as originally laid down by the founder
The base of the stalk represents the flame of the love of humanity
The vein pointing upwards through the center of the trefoil represents the compass needle pointing the way
The two stars represent the Promise and Law.
