This antique pin was most likely made at the end of the 1800s or the beginning of the 1900s as this was the height of the era for Japanese art. Japan had been a closed society before 1853, when they opened themselves to trade, so very little was know about their art prior to this time. When the western artists first saw the amazing works in printmaking, painting and ceramics they were so taken with it it began the "Japonisme" craze that soon spread to the public at large.
This circular pin in glazed ceramic has the image of a Japanese woman in tradition dress with a small child. The image has beautiful purples, yellows, greens and oranges with gold leaf accents. The border is in a deep blue with gold decoration and a gold outline at the edge. The back of the pin has a Japanese character in black.
The pin is marked "W.G.&S." and has the hallmarks for 9 karat gold. I believe there is an anchor for Birmingham, but the letter mark to provide a date is worn off. The d as 10 karat gold.
The pin is 1 5/8 inches in diameter, about 4 cm and weighs 15.1 grams. It is in excellent condition.
