I polish the bronze facets to high shine by hand to keep the edges as crisp as possible. The bronze is sealed with the same kind of wax used by museums to preserve artifacts.
Come with a pair of clear rubber backings. The earrings pictured are sold, I cut the facets by hand and every earring is different, the style is the same.
Made on demand takes me up to 6 work days.
