Native American (Navajo) Made Key Ring With Turquoise. Marked Can\'t Read For Sale

I got this from a lady who lived near the Navajo reservation and she had many items from them

I can\'t quite read the markings on the back, but maybe someone knows. I will add a few better photos when it\'s light outside, so just ask,please. Unknown material it\'s made from. Please see the photos as part of the description also. Anymore, I only sell things AS IS WITH NO REFUNDS, so please ask questions if needed. Thanks for looking!
