This is a sterling silver knot ring in 18 gauge wire. Knot rings use wire wrapping techniques to create a gorgeous random swirl in the middle. After it has been made to match your desired size, the ring is tumbled for several hours for extra strength and shine. The end result is a unique and pretty ring that you will enjoy for years. This is a custom piece, and I can make it in any ring size (from 1 to 13) Please let me know the size you'd like in your notes when you place the order. This will ship 3 days after payment has been received. The swirl will not be identical to the one pictured, but will be a similar size and shape.
