"Old Beautiful Tie Pin In 18k 18k Solid Gold And Aquamarine Blue Stone."
This tie pin is in very good condition. It is decorated with a beautiful little aquamarine. An illegible hallmark is present on the top of the stem. I tested it with a touchstone and my jeweler confirmed it to me, it is indeed solid 18 carat gold. Length: 6 cm. Weight: 1.60 grams. Fast, careful and very secure shipping
