Help identifying tribe and possibly artist of a ring

Hi, I came across a ring in my moms things after she passed and I’m trying to find out what tribe it’s from and the artist who made it. Initials “KS” on back.

This is very popular 1980s style of Navajo jewelry. Initial hallmarks are very difficult to identify, especially when the style is not unique. KS could stand for a number of silversmiths. Thanks for sharing.
