10g sterling silver wire was annealed (softened), hammered thin in 3 locations, and then twisted with an electric drill. Quite a fun process actually! The wire was then bent into a half circle, jump rings added and strung with a 20" length of sterling silver chain. The entire necklace hangs 9.5".
This necklace is made from Argentium wire which has a very low tarnish rate. An anti-tarnish pad comes with the piece and should be kept together to prevent tarnishing. A soft jewelry cleaning cloth should be sufficient if needed.
