Gorgeous gold washed vintage sterling earrings by Burkhardt

The Canadian jeweler Burkhardt created some lovely sterling pieces circa mid-century, this time clip-on oval earrings in a gold plated or gold filled finish with a finely etched floral design, about 2/3 inch long. They are in perfect shape. I have also listed a couple of similar pairs of etched sterling earrings, one by Burkhardt (silver), the other by Forstner (also silver but round), and a gold washed round brooch (signed WFS) that would pair very well with these earrings.
