Unsigned Navajo Ring. Help identifying type of turquoise & design

Hello all, like to get more info on a ring.

Interested to know the type of turquoise & symbols stamped to the shank of the ring.

From my brief search, would Royston or King Manassa be the type of turquoise?

Ring is unsigned.

Look forward to some feedback & thank you in advance

Royston Turquoise, the designs done have a meaning. Thanks for sharing, beautiful ring.
