This is a great heavy cuff I’ve always assumed is by Ernie Lister. It appears to be hand-worked thick ingot. The turquoise appears natural and just glows. The Matrix is a deep brownish-red, my pictures don’t do it justice. I have my opinion, but I’d appreciate you all weighing in.
Also, the hallmark is not consistent with what I can document in my resources. I don’t have Hougart’s most recent edition. Is anyone familiar with this hallmark for Ernie Lister?
