Hi, I'm new to this; I need some help identifying my pearls. I have a cultured pearl brooch and a set of earrings from Mayuyama & Co. (red velvet boxes) I received both from my father who used to travel to Japan on business in the late 60s to early 80s. I also have a brooch from Uyeda (brown velvet box) also from my father and also from japan. I've had them for years and just decided to look them up. Uyeda has images of cultured pearl brooches on line and I have seen ones that are similar to the one I have. The Mayuyama and Co. I haven't found anything. Hoping someone here can provide some info.
