The kinetic gear necklace is made from genuine hand worked brass coated gold and blackened silver. The chain is crafted of gold plated silver. Pendant size: Length is 35 cm (13.8'') width is 5 cm (2'') The kinetic gear necklace is one of my favorites in this collection that I based on the metro line maps from New York, Moscow and London. This piece is so light and easy to wear every day. It will pair well with almost any neckline and outfit in your wardrobe. The best part is that you can adjust the pendant as you wish to create a whole new look! All of my items come beautifully wrapped in a gift box. Do not use perfume or water on this jewelry. It is possible to special order this necklace to the chain length you desire.
