It measures 17.5 inches from end to end. Each of the sand cast pieces measure 1.75 inches wide (west to east) by 1 1/2 inches high (north to south).
Weight is a heavy 63.4 grams. Slight chisel marks from tools used to hand make it, which I personally love. Dates to the 1960's-1970's.
I have consulted with an online group of Native American jewelry experts (ask me where if you'd like to know) about the openings on the back, which they say is of no import.
