Edwardian Hand painted Porcelain Forget-Me-Not Brooch

I found this sweet little porcelain brooch at the thrift today. I think these are charming and they remind me of my grandmother who used to do china painting. She never made jewelry, but just looking at this type of work reminds me of the lavender and clove oil she used to use to grind the dry mineral colors. I believe this pin dates from the early 20th century.
The pin is 1 and 1/8 inches in diameter.
