I have taken a disc of sterling silver and cut it to represent 2/3 of the circle and 1/3 of the circle. Just a little more unique in shape than half and half and I love asymmetry.
This necklace can be made with a large, 45mm disc of sterling silver. The larger, 2/3 necklace is 30 inches in length and the smaller, 1/3 necklace is 28 inches in length and both are finished with sterling silver cable chain.
Custom lengths or combinations welcome. I love to mix metals, so I would be happy to pair these discs with yellow or rose gold filled chain or oxidize the sterling discs or chain.
