This is a lovely sterling silver and pearl pin by Mikimoto, Japan. This is an early piece with a trombone catch and probably dates to the 1940s. It is large, measuring 2 7/8" x 1 5/8", and is set with 11 pearls ranging in size from 4.5mm to 5.6mm. The pin is in excellent condition and is fully signed "Silver 950" together with the Mikimoto mark. See my other items for the matching earrings.
