Light blue glass oval star clasp

As you gaze into the clasp you see a six-pointed star pattern in a darker blue. The tones of blue vary through the centerpiece, almost like it is a watercolor. The star pattern is pronounced and adds a nice bit of visual interest to the clasp. It is a vintage German post WWII piece of glass. The centerpiece is bezel set in a hand-made sterling silver box clasp. The clasp is 45 mm from ring to ring. It is 18 mm wide and 13 mm high at the top of the domed centerpiece.
