What are some of the best ways to clean diamond earrings in gold settings?? I used dishwashing liquid and a toothbrush earlier today and it looks really spotty up close under light. I recently purchased two diamonds from BGD with a total weight of .67CTs. So I was just trying to see if I can make out the arrows even though they arent very big. After I cleaned it though, it looks like a bunch of really small water spots on it and I was wondering if thats ok?? I only see it when I shine an LED light onto the top of it though.
