I have had these for a long time. Liked them because the color seems unusual to me, they look blueish silver to me
. I have been trying to find out more about them and their value, but not having much luck. Hopefully someone here can help. The box they came in say FURUYA Tokyo japan Cultured Pearls of Distinction. They all seem to measure 7 mm. The clasp is marked with an F and 925. Thanks in advance for looking. Hope someone knows something about them.
