For sale is this mid century, BUICK Parts Master 10k Solid Gold and Diamonds Charm. It measures over 1/2" wide, weighs 2.9 grams and is set with four small, clean, clear diamonds. There are solder marks on the back leading me to believe that this was originally a lapel pin, but it was converted into ta charm to be given to the woman who worked for Buick at the time. No damage.
