This lovely little item is Damasquinado de Toledo and is very versatile. If you are not male or don't use tie clips do not write this piece off. Although it was obviously designed as a tie clip, it could also be used in a boutineire slit on a jacket or (and this is the one I like) slide it over a hardwire necklace or chain and wear it as a slider or pendant. If you intend to use it as neck jewelry, have a jeweler sodder the end of the clip. Otherwise you might lose it. Length is 1.5 inches and width is 3/8 inches. Condition is excellent vintage. The gold in this piece is in two tones.
Damasquinado de Toledo is a centuries old technique of applying gold to blackened metal. Backs, frames and prongs of Damasquinado de Toledo is always gold plated. The technique was brought to Spain by the Moors. Toledo, Spain is the center of production now.
