Vintage Austria Crystal Dome Brooch

The pin is so much like what Schreiner made and it is in excellent vintage condition measuring over 1 1/4"x 1" (please see photos, measurement is approximate) but it was likely made in Austria. I cannot tell that it has ever been worn. I never had a reason to wear it myself. The construction of the jewel is very good and unsigned. Please see photos for approximate measurements and details.
