Hi! I want to learn more about how to spot leakage in a diamond with my naked eye, specifically in diamonds labeled GIA XXX but have uncomplimentary angles (like 35/41 or 33/40.6). I’m not referring to the diamonds that are clearly out of ideal range with pavilions exceeding 41.2 but the ones that labs label as “ideal” cuts when they really aren’t ideal in the sense it is used on this forum. I know idealscopes and ASET images are the go to, but is it possible to spot leakage in such diamonds to the naked eye?
