This was a custom necklace made especially for a customer. The necklace comprises of 2 separate silver king chains that end in Viking wolf heads. They are connected at one end by lobster clasps and the other end has wolf heads that are designed to hold a split ring to suspend a Thor's hammer, or other Viking pendant. The chain can be made in any width and any length. This example was around 10mm thick with 8mm wide wolf heads.
If you want a custom necklace making like this, or any other necklace then we will just need either a picture, or the original necklace to replicate it for you.
