I usually do not pay to have metal items tested which are marked with sterling or gold hallmarks; items have only been tested for metal content if noted in description. When it comes to designers, I go by the markings or tags on the items, and if an item looks like that of a particular designer, I may mention this for descriptive purposes but will make clear whether it has that designer's mark or not. Items have not been cleaned unless otherwise noted. No significant noticeable damage unless otherwise noted in description. All items are used vintage unless otherwise noted. Thanks for looking!
