First of all, what is Rose Medallion? Rose Medallion is a 19th and 20th Century Chinese Export Porcelain. Rose Medallion has a unique characteristic way to identify it. There is often a central medallion of a rose, peony or even birds. The dominant colors are usually pastel pinks and greens and can also include red, blue, orange, yellow or gold. Rose Medallion can be found as plates, bowls, cups, vases and teapots. If there is no mark on the underside, the piece dates 1850-1890. If marked "China" it is 1890-1915. "Made in China" dates the piece after 1915. If it says, "Made in Hong Kong" or has Chinese characters these pieces are not considered antique because they are too modern.
