Chain is optional and silver plated. The chain length includes the pendant length; if you order a 16" necklace, it will be 16".
This listing is for a pendant that is similar to what you see in the images. There are two wires on each end for attaching to chain for a necklace or bracelet. It is already made and ready to be shipped from the US!
This pendant was created in my studio, first with porcelain clay, which is formed and dried. After drying any hard edges are cleaned with a sponge and dental tool. It is first fired in the kiln to around 1900 degrees F. Then it is dipped in glaze, dried, and fired again, this time to ~2300 F.
