These elegant earrings measure ca 8mm square and are handcrafted individually from brass. The stud itself is 925 Sterling Silver (if you get itchy ears from any other material like I do - this is for you! ) Made to be comfortable everyday earrings. I cut out circles which are then domed in a dapping block and a post soldered to the back. If you have a preference in having a particularly long (10mm) or short (8mm or less) posts, depending on the thickness of your earlobe, just let me know in the notes box at checkout. JEWELLERY CARE: * remove during sleeping, bathing and applying perfume * all jewelry is finished with a coat of Renaissance wax which provides a barrier so that your jewelry stays shiny for longer Thank you for supporting small businesses!
