US guides
GIA grades carat, color, clarity, and cut for rounds. Fancy shapes still need the video.
US shoppers sometimes pay extra because a listing says GIA and then skip the plot. The plot is where an SI1 either hides or sits under the table.
Match the GIA number before the diamond ships to the US. Measurements tell your jeweler how to build the head.
Open natural listings and the certificate together. Reject a stone whose video disagrees with the grade you liked on paper. 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.
