Help With Maker Sterling Stone Bracelet

Hi all, I'm hoping someone might know the maker of the this bracelet - I'm not even sure if the mark is letters or a symbol. May a Navajo bracelet? Would this be referred to as inlay stones?
any information appreciated
thanks for looking

 

looks like a Zuni inlay.......but I can't make out the mark..

 

sugilite, man made opel..? turq , spiny oyster , jet...and the green ????

what they are supposed to be.......

 

Thought inlay was more of a Navajo specialty?

 

there's all kinds of cross pollination...

Navajo do it too...but I like to think of Navajo as big turquoise and silver work..

/

.when the Navajo inlay...u still tend to get the silver stamping as well...



while Zuni artists concentrate on the stones..
.like the petite point , and needle point...



.and the crest images..



CX's bracelet is light tourist fare , and could be either or...
but I see Zuni from the classic stone selection.. and thicker black borders.




I truth , I'd be lying if I said I could tell these apart on a regular basis......

 

Wowser, those are some big pieces of turquoise

thanks komokwa - the mark just isn't very clear I'll look in the direction of possibly Zuni inlay

the only one I know or think I know is the opal
