This is 195 grams of silver,copper and brass expertly made chain with a maximum flexibility with no flaws. It is a tad under 2 inches wide and has a wearable length of 17in. It is signed Mexico. It has an ominous presence and is fabulous with all the warm tones in our wardrobe. All three of these metals have a different melting point and it takes great time to produce this piece. It is a pre-1948 piece and is simply stunning, just LOOK AT THAT NECKLACE!
