This is a sharp looking black tungsten carbide necklace, it features one of our most popular designs the Manhattan links. The surface of this necklace is finished to the mirror-like high gloss finish. This is quite a hefty necklace, weighing 12 grams per inch, e.g. a 24" one weighs 288 grams, comparable to a 18K chain. As with all our tungsten chains, it uses our specially designed security to hold the links together so that it will never break and fall off your neck.
