It is not signed but acid tests as at least 14 karat gold. It is in Very Good vintage condition with just expected surface dirt and scratches as well as small imperfections in the natural stones. As is usually the case with these older pieces, it appears one or more of the turquoise cabs may have been replaced over the years. There is a little clear residue around one or two and some are of different shades of blue (and different shapes, heights/profiles), which really adds to the pin's antique charm, beauty and interest. Feminine and romantic, this finely rendered antique 14 karat gold, turquoise and pearl monogram pin is an outstanding example of the genre of monogram jewelry.Simply exquisite, it will be a superb addition to a collection. Of course, it would also make a terrific gift. You could bear to part with it, and will come to you in a gift box, just in case. This brooch will bring the opulence and sentimental romance of jewelry history and gentler times to your collection. Please see our other listings for more great vintage jewelry. Both methods include gift box. Powered by SixBit's eCommerce Solution.
