The enamelled “Dot & Leaf” Line is vast. Enamel in general is prevalent on Neiger designs as it was with Rene Lalique. It broadly falls into two categories. Those 2 are cold painted enamel and fired enamel, which is more glossy. The dot and leaf motif is always fired.
Note that some designs include a different color dot to the color of the 2 leaves. The most used seems to be a red enamel dot.
