Hopi Knifewing Ring - Size 9

This sterling silver Hopi overlay ring is a figure of Knifewing, an intelligent force of nature that is a guardian and protector.  There is so much detail in this ring - more about the overlay jewelry technique below.  Hallmark on the back is "E" with an elongated bottom line. Size 9 - Knifewing 1.5" H x 1" W Hopi Overlay jewelry is made by sawing out two sheets of sterling silver the same size.  Hopi jewelers texture the bottom sheet with hatch marks.  It is then oxidized to turn it black.  The design is drawn on to the top sheet of silver which is then carefully sawed out with a fine jeweler's saw. The edges are filed smooth.  The top piece is soldered on to the bottom piece.  Sometimes, there are many small pieces that are also soldered on to the bottom sheet of silver.  It is then polished to a high sheen.
