The solid Sterling Silver Acorn Charm measures 3/8" from top of the cap to its bottom point, about the size of a medium sized pearl.  The Silver Oak Leaf is 3/4" long, 3/8" at it's widest point.  We've enlarged this photo to show its intricate details.  There are a couple of small jump rings connecting the Acorn to the Oak Leaf, they allow for gentle movement similar to an acorn on its branch.
