I just received the beautiful Tom Singer cross. But I do have a question
about the cross. It is stated to be sterling but the front surface is copper
colored. Can you explain the process used to make it that way?
The cross is solid sterling silver and Tommy Singer (and his son Richard whose crosses I am using to illustrate this article) oxidizes part of it (the black areas) for accent and puts a layer of 12 K gold on other parts of the design. This is called gold filled.
