I just got a diamond engagement ring five days ago. It''s a .86 oval diamond in a 6 prong setting with Pave set diamonds down the side. Last night I noticed a horizontal line across the middle of the diamond (viewed from the table). I did not notice this before. Depending on how I turn the diamond, sometimes the line looks dark, other times it looks like a glass color, and other times I see two black spots. No matter what it''s always there, right above the 2 prongs at one end of the oval, but near the center. No matter which way I turn the diamond, it stays in the same place. It is not the refelction of the girdle. Like I said, I''m viewing it from the table. Is this a break in the diamond? Or is it some type of reflection from the setting below? I''m bringing it to another jewleler today before I bring it back, but I want to know what everyone here thinks. This is not normal, right?
