3 x 4,5 cm copper cloissoné enamel over copper. Leveled surface. Transparent and opal enamels. More likely to be a pendant.
It is not any real species of Iris, but a mix of shapes and colors following my idea. It came out a bit darker than intended, but perhaps this way it makes a better contrast with the white background.
Edit: It is sold, it will be a pendant.
