Treatments change how you should read the grade and the USD price.
Carat Mate’s catalog standards favor untreated stones. If a report mentions a treatment, that stone is not the same product as an untreated diamond with the same letters.
Do not pay untreated prices for a treated stone, and do not assume every low price is a treatment. Read the report.
The certificate is the place the treatment would be disclosed, not the photo caption. 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.
