This piece is a very wonderful European necklace with a quality that is timeless yet old. This necklace is made up of a simple interlocked silver toned metal chain with a spring ring clasp that hold very well. The necklace pendant is very well crafted having many bezel set glass rhinestones that are set into marcasite. The marcasite is in the form of a "T" that can be seen more vividly with the dangle included into the design. The upper pendant section contains a small marcasite dangle with three glass rhinestones set into it. From this a green swirl glass stone dangles. This piece is gorgeous and is capped on the bottom with a piece of marcasite decorated with some small glass rhinestones. The necklace is also said to be either a French or German item as it has a small hallmark on the back of the pendant that indicates this. This hallmark is located on the marcasite dangle that looks like a stamped "L" but it is hard to be sure. The piece is without a doubt beautiful and old just by the natural patina that is on the metal. This piece measures 25" long with the pendant measuring 1 3/4" long by 1 5/8" wide. A beautiful piece with a truly old world kind of look to it.
