Forever in season, a collection of vintage German glass strawberries (beautifully-rendered buttons for which we fell immediately upon sight at a favorite antique spot) grow wild amongst strands of polished white moonstone.  You'll be smitten and swooning for the flashes of iridescent hue in the beads, not to mention the bright and cheerful berries at their side.  A gilt copper toggle at back is adjustable from 17 to 18.5" in length.
