Thanks...(Not my photos). I thought it would be helpful when people ask for Pearl Maker ID for their inherited pearls. to have them all in 1 place. If you have any to add, please do! (I just read somewhere..that there was a disaster or economic downturn that caused many Japanese pearl jewelry companies to go out of business in the 50's & again in the 80's) So it would be nice to have a record of these, since Google does NOT help.
