Here's a very attactive "Yei" figure pin that we purchased at a jewelry & crafts co-op on the Navajo Reservation in northern Arizona.
This sand cast pin was make to depict a traditional Navajo "Yei" figure.
Here's some information regarding the Yei in Navajo culture:
Yei is a shortened version of YeiBiChi, a holy figure in the Navajo culture. Yeis are the supernatural beings that allow communication between the Navajo people and their Gods. One Navajo artist told me, “They are the keepers of the door to the other world.”
This pin measures 2+1/4" long and it weighs 6.2 grams. The back is stamped sterling and has the artist's hallmark, K.
As you can see in pictures displayed below, the artist adorned the pin with a small, round, turquoise stone and a few hand stampings.
