I don't know why, but for some reason it helps.
These new necklaces are now in my etsy shop. They are all mixed metal, with sterling silver and gold vermeil.
Gold vermeil is a heavy gold plating, 24K, over sterling silver. It is a gem quality plating that is 40 micro inches thick with a fine layer of nickel over the silver. The plate is very reliable, with a soft satin finish.
