Can someone identify this buckle if it’s Zuni, Hopi or Navajo and who “DJ” would be? Also, how old would this be?
This looks to be Navajo made. I am not familiar with the hallmark. I used Hopi Silver by Margaret Wright that is a good resource bringing us up to 1990. Maybe this is by an artist who began after that date. You might find a helpful resource here http://www.hopiartstrail.com/22-artists/jewelry
