US guides
There is no GIA grade named eye-clean.
Set a VS2 floor if you do not want to inspect every natural stone. Include SI1 only when you will watch the video on your phone the way you will look at the ring.
Larger US center stones show the same grade more. A 2 carat SI1 is a different bet than a 0.70 carat SI1.
Filter natural inventory, then reject any stone whose dark spot you can find in a few seconds. 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.
