This one-of-a-kind curved necklace features 24k gold and sterling silver. I use the Korean Keum-Boo technique to create this piece. The curved piece is done by cutting out thin sheets of 24k gold foil and fusing them to a sterling silver tube using pressure and heat. The necklace's clasp is made of sterling silver, as well. The standard size for the necklace is 16", but I can create it in any length you like. If you'd like a longer chain, please let me know when you place your order. I can lengthen the chain up to 20" for the same price.
