I believe this is a Ciner piece, it has the weight, the well crafted clasp, and higher quality look that Ciner pieces are known for along with the exact same lines and gem patterns, however there is no Ciner signature on the back, just a serial number in a rectangle. Lovely piece and only condition issue is two turquoise colored gems missing (see next to last photo highlighting these missing stones). Measures 1-5/8” tallest x 1-1/2” at widest. Please see all photos and feel free to reach out with any questions. Shipped with care via USPS
