Dishta Style Zuni Cross, channel set turquoise. Small size, great to layer up!
18 in thin chain, spring ring clasp.  Clasp marked sterling. I tested the chain, clasp and pendant, all sterling silver
The clasp must have a spring inside it b/c it jumped a bit with my magent, but tested as sterling. 

Love this piece, no marks
