Sterling Silver Native? Glass Necklace

Beautiful panel necklace with CZ and glass pieces. The orangy pinkish stones have that opal look and these look like they are glowing. Really pretty. I tested on the presidium and the maroon center seems to be glass the clear CZ and the glow ones glass. It’s very well made possibly Native? Not sure. The back is hand signed, but I couldn’t tell you what it says. It’s also Marked 925 and has been tested. The necklace is 16 inches in length, has a hook clasp. It weighs 48 grams. In great condition.
