This is a beautiful silver and cultlured pearl brooch by the Japanese Company Mikimoto. This vintage silver brooch is adorned by four perfect Mikimoto cultured pearls which have a very strong lustre. The Japanese Company, Mikimoto, are the most celebrated of Pearl jewellers. Mikimoto actually invented the technique for culturing pearls in the late 19th/Early 20th Century. I would estimate that this brooch dates from the 1970's because of the design and the Company's use of etched surfaces to add depth and contrast to the silver. The pearls are arranged in a graduated order on top of the brooch. However, the design is a clever one because the brooch looks stunning whichever way it is pinned - pearls on top or pearls dripping down! The largest cultured pearl is approx 5 mm in diameter, the next is 4 mms in diameter and the two smaller pearls are each approx 3mms in diameter. This pin is a signed piece, it has Mikimoto's 'M in a clam shell' mark along with an 'S' for Sterling Silver, clear to see on the reverse. The brooch fastens with a secure roll-over type clasp and it is in excellent condition.
