When buying a loose diamond, it is important to verify that it has been evaluated by an unbiased expert gemologist from a trusted gemological laboratory. The gemologist grades the characteristics of the diamond using industry-accepted grading scales as set forth by the Gemological Institute of America. The laboratory issues a certificate or diamond grading report detailing the characteristics of the certified diamond, as well as basic information like carat weight and measurements.
When selecting loose diamonds with a report from a trusted gemological laboratory, you're assured of the diamond's quality. Additionally, because all certified diamonds are graded by experts using similar grading scales, it is easier to compare them based on the four Cs - carat, color, clarity, and cut - rather than relying on your own visual judgment or the jeweler's knowledge. Certified diamonds will generally hold more value than diamonds that have not been certified, especially when graded by established laboratories like the GIA, AGS, or EGL.
Before purchasing loose diamonds, it is imperative to understand the factors that add to their quality and value. Gemologists and diamond professionals use four key factors, known as the "Four C's", to evaluate and classify certified diamonds. These value factors - carat weight, color, clarity, and cut - along with shape, measurements, fluorescence, and certification directly impact the appearance and price of a loose diamond. In our diamond education section, we thoroughly explain each factor and provide insider advice to guide you in finding the perfect diamond.
