Two Turquoise and Silver Rings / Circa 20th Century

Finally after a long holiday weekend my friend was back to work at Salvation. The jewelry had really piled up and we went through some of it. She had pulled all the rings for me to look at. For some reason she trusts my judgement...lol. The first ring is marked .925 sterling Berse (Studio Berse). It's turquoise with orange coral beads around the outside. One bead had cracked and the top part is missing. The other cashier was going to buy it but changed her mind and let me have it. The missing bead bothered her. Not me... I was very glad she changed her mind ! This make of jewelry is sold on HSC so nothing super but still a nice piece. The other little silver ring is marked with an (M) in brackets maybe Mexico?? .925 . It's quite small and barely fits half way down my little finger. The band looks like two small ones close together but it's solid. They were both very dark and dirty. A few passes of jeweler's cloth brought back their sterling luster. -Mike-
