Vtg Sterling Silver Green Turquoise Navajo Pearl Necklace and Earring Set Signed. I'm not sure who's hallmark this is but it is "SB" with a star around it. From the research I've done it looks like possibly Sam Begay or Sam and Betty Sperica.  Such a beautiful piece! Total length approximately 20" from end to end. Great vintage condition showing light wear from age and use. There is one elongated bead that has a few dents on either side. Please see photos and feel free to ask any questions you may have. Thanks for looking!
