US guides
SI1 is the first clarity grade where US shoppers routinely get surprised.
A small white crystal at the edge can disappear under a prong. A dark crystal under the table will not. The plot, when the lab prints one, tells you which case you are in.
Compare the SI1 USD price with a VS2 at the same carat. Pay the difference only if you can already see the SI1 problem.
Watch every SI1 on the 360° view before it ships to a US address. 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.
