Is the wearer of the ring ... in a room with white wall?
... yellow walls?
... great northern exposure?
... incandescent lighting?
--- some weird new CFL bulbs?
Is the stone ...
.. old cut?
... with a bruted girdle?
... OLD bruted girdle, or recently dipped in acid bruted girdle?
--- fluorescent?
... blue flour, or yellow, or green, or red, or ...?
Is the wearer of the ring ... the kind to obsessively steam-clean?
or ...
.... the kind of person who, like one lovely lady I know, the sort to hold her hand out to you proudly while telling you that she hasn't taken it off the whole year she's been engaged ... and you can see she's telling the truth via the accumulated soap beneath the pavilion? (BTW, it was a D. It's just that nobody would have guessed unless they were going for D-is-for-DOVE.)
And that's just the tip of the iceberg.
I can tell under GIA grading conditions. I can tell when the stone is loose. I can tell if there's something ridiculously egregious about it, like, uh, sister, I hate to tell you this, but your diamond is showing adularescence, which is ... highly unlikely.
But in normal life circumstances, when, say, a friend is showing me her decently cut stone in a quick flash at her engagement party? NOPE.
But I guess this question is about a specific set of circumstances that we're all imagining differently. Braga, what kind of scenario are you wondering about?

Maybe it is just seeing strangers rings he is speaking about, but if I see a ring for a minute I can see it is a different color. Or at least I think I do.
Now I am wondering after Paul writing he agreed people could not see![]()

Maybe it is at work, and it is your colleague, or maybe a stranger is paying at the cash register in front of you, or you are having lunch with a friend and she is wearing her ring and sitting right across from you...color detection in real life scenarios within a relatively close distance.
