GIA and IGI are two of the best-known diamond grading names shoppers see when comparing natural and lab-grown diamonds. A report helps, but it does not replace careful review.
What a diamond report shows
A report can document carat weight, measurements, color, clarity, cut information, polish, symmetry, fluorescence, comments, inscriptions, and a report number used to identify the stone.
GIA in plain language
GIA is widely recognized in natural diamond grading and is also used for lab-grown diamonds. Many buyers associate GIA with strict grading standards and strong market recognition.
IGI in plain language
IGI is very common in the lab-grown diamond market and is widely used across modern diamond listings. Many lab-grown diamonds shoppers compare online come with IGI reports.
The report is not the whole decision
Two stones can share similar grades and still look different. Proportions, face-up size, video performance, shape, clarity placement, and setting fit all matter.
