Looking for artist

Have a beautiful silver bead and gaspeite necklace and another piece (pendant) with SS on back. Would like to idnetify the artist and if living, locate. Have “Hallmarks of the Southwest” so I found 5 names with use this mark. How can I pursue this farther. Have searched these names on internet but not too good at this. Have good photos.

Photos would help. You also see SS used for sterling silver on occasion.

We also have a piece with “SS” on the back. It definitely appears to be a signature, not a description of the material, but I could be wrong. Here’s an image of the initials and whole piece. Any information would be most appreciated.

It is very interesting, can you give me close up looks? Also, any idea on age, have you had this a long time?
