The Dish is decorated in a deep cobalt blue floral pattern called the Gillyflower pattern which is an old English name adapted from the French with a central carnation or pink, surrounded by six smaller sprigs and a butterfly on the outer sides of the dish. The pattern derives from the French Chantilly designs. Derby made a very similar pattern which was then copied by Caughley and Coalport. The base has the shaded Worcester crescent mark painted in blue. This is a rarer Worcester pattern.
