Hello, I purchased a ring from Etsy uncertified ( I know, I know) but I fell in love with it. It said it was an H SI1 I got the ring and it just looks yellow. In some lighting it's better then others but I don't know if the fact that it's 18K and needs to be rhodium plated so it's picking up yellow tones from the setting? I took this to my local jeweler who said she would grade this as a K possibly an L!! What do you guys think is it the reflection from the lack of rhodium plating or will that make it worse with the contrast of the white and possibly yellow. I just know that H colored diamonds are not yellow. =( I can still return it and am thinking I should even though I am in love with the setting. =( This is it next to a Tiffany G earring.
