I have had my engaement ring for about a month and a half and the other day, I noticed an obvious piece of carbon in it. I know that it couldn''t have been there before because God knows I''ve been staring at it enough. My fiance looked at it with a magnifying glass before he bought it and didn''t see any carbon in it. This carbon is not something that you even need a magnifying glass to see. It''s very obvious to the naked eye. I''m wondering if it''s possible for carbon to just show up or if something I did could''ve made it show up. Is there anything I can do to fix it?
