Does anyone know if all mikimoto pearls have stamped clasps? I have a set that was purchased in Japan in the late 50's/early 60's and is in a mikimoto box (I know that may mean nothing) but the clasp has no stamp. I am interested as the strand was appraised at almost $1500 but, I have an estate jewelry buyer that wants to purchase them for $200 as he indicated that no matter when or where mikimoto sold their necklaces, all clasps were stamped. (these have not been re-strung)
thanks
