For sale is this really nice, 10k solid gold brooch that has a fold down loop enabling you to wear it as a pendant if desired. The piece measures 1" wide, is set with an 0.20 point clean diamond and weighs 4.8 grams. The pin has no damage, but there are two small flakes on the girdle of the diamond. Great locking clasp. Not marked, of course, because of its age, but it has been carefully acid tested.
