This is a beautiful Art Deco antique diamond stickpin featuring a platinum top set with three antique diamonds with milgrain detailing weighing in total .20 ctw. The head of the pendant is 11.6mm wide by 15mm long. The overall length is 70mm. The stick of the stickpin has been tested as 14k yellow gold. While lovely as is, I think this would make a beautiful conversion to a pendant or ring if desired. If that is something that would interest you I can inquire as to the cost with my bench jeweler.
