Obidome Brooch Kimono Sash Clip Japan Antique Flower in Gold Red and Black

This obidome sash clip has been converted into a stunning brooch by attaching a pin back to the porcelain or pottery piece
2 1/8" wide by 1" tall, and about 3/8" deep dome
A gold and red flower is painted on the front, with white around the flower's center. The white enamel is slightly raised. The background is painted black. The pin material itself is white
This is in the style of Kutani-ware. However, the mark would exist under the pin attachment, so I can not confirm the signature or mark on the back
