GIA diamonds can seem more expensive when compared to diamonds graded by other labs. You may be able to find diamonds with a similar grade (as per the certificate) at a cheaper price with other labs’ grading reports. However, the grades of some of them tend to be looser, meaning you may be paying for what you think is an H color VS2 clarity diamond when in reality it should be a J SI2. The GIA’s grading process is slightly more expensive than some other labs, and the grades they give are stricter than low-quality labs like the EGL. However, this is a small price to pay to ensure you’re buying a diamond with a fair and accurate certificate.
