Because diamonds are formed in nature under turbulent conditions of extreme heat and pressure, diamonds cannot be 100% pure. As mentioned, the definition of a Flawless diamond is one that has no inclusions visible under 10x magnification. In reality, no diamond is truly flawless. However, despite the grading report’s prestigious title of “Flawless,” Flawless diamonds are not truly flawless. In contrast, any internal inclusions such as surface grain lines that extend into the diamond’s body would cause a diamond to fall out of the category of Flawless and Internally Flawless diamonds-and such inclusions cannot be removed with further polishing. Although these blemishes can be removed with further polishing, diamond cutters choose not to continue polishing in order to avoid decreasing the diamond’s carat weight and risk reducing its monetary value. When reading the grading report of an internally flawless diamond, you may see comments such as “minor details of polish are not shown,” “surface graining is not shown,” and “minor details of finish are not shown.” These comments are normal because they refer to the namesake inherent blemishes that distinguish an internally flawless diamond from a flawless diamond. Despite this extreme difficulty in detecting any visual differences between internally flawless diamonds and flawless diamonds, the internally flawless diamond price differs greatly from that of a flawless diamond. Even trained gemologists using microscopes may have a difficult time. It is nearly impossible for the naked eye to differentiate between flawless and internally flawless diamonds rings. Thus, a Flawless and Internally Flawless diamond have the same internal clarity, with the differentiating factor exiting as a matter of the polishing of the diamond’s facets. Any surface blemishes such as surface graining, naturals, extra facets, or polish marks would downgrade a diamond from Flawless to Internally Flawless. Essentially, the difference between a Flawless diamond engagement ring and an Internally Flawless diamond ring is the presence of blemishes on the diamond's surface.
