These lacey filigree pins are so pretty. Here is one by the renowned maker Krementz. It is 14K gold and Platinum with a center Diamond. It is 2 1/2" long and 5/16" wide at the widest. It weighs 3.7 grams.
The nice and sparkling Diamond is 0.07 CT and the contrasting Rose Gold inserts help draw attention to the delicate Diamond.
Krementz has a long history in Newark, New Jersey jewelry making. They used excellent techniques and materials to make sought after jewels. Why have any old bar pin when you can have a signed piece instead.
