US guides
Do this with the video on a phone in daylight, and again at delivery if the diamond is returnable.
Night restaurants make every diamond look whiter. Do not buy D-color money from a dinner photo.
Larger stones show the gap more. Repeat the daylight check at the carat you are buying.
If you only have the listing, use the photos plus the grade, then use the 3-day window in real US daylight. Carat Mate ships the certified loose diamond and its lab report to United States addresses. Prices on the site are in USD. Wrong-item returns may be considered within 3 days of delivery, subject to review.
