Dating to the 1960s or so, may I offer this stunning 835 Silver bar pin. Manufactured in Worpswede, Germany by Helmut Von Kleist, the bar pin is handmade and features a stamped design top and a center oval cab of amber (possibly synthetic but I have no way of telling for sure). Safety catch at the back to hold the pinstem in place. Condition is excellent with a dark patina. I lightly polished the piece and I am sure some of the pink polish residue shows in the crevices of the design - a light wash will take care of this.
Metal Content is 835 Silver with Hallmarks to the back of the pin that include 835 Von Kleist Handarbeit.
Size is 2-1/2" long x 11/16" wide at the center. The center design alone measures 13/16" x 11/16".
Weight is 9.9 grams.
Final Comments: Stunning and from what I can glean from the Internet, quite collectible!
