Rainbow.

So that the cold enamel colors do not run into each other when applied, a delicate bar made of 18-carat gold divides the six tiny color fields. The colors are filled in by hand one after the other and in several layers exactly up to the bridge and dried again and again. Finally, the Wellendorff goldsmiths apply a layer of transparent cold enamel across all bars. This creates a surface tension over the entire color field, which makes the surface of the earrings soft and supple and makes the colors more intense. In addition, the highly polished background of the colorful cold enamel surfaces reflects the incident light like a crystal, which means that the rainbow colors of the earrings shine from within.
