Every diamond is unique, and carries its own set of internal ‘birthmarks’ as a result of the chemical processes involved in its creation. These are known as inclusions. Imperfections on the outside of a diamond created during the cutting and polishing process are known as blemishes. The GIA grades a diamond’s clarity on a scale that ranges from Flawless (no internal inclusions or external blemishes) to Included (obvious inclusions, visible to the naked eye). Diamonds with fewer imperfections are rarer and therefore more valuable. Pragnell’s engagement rings only feature diamonds with a clarity rating of SI1 (slightly included) or higher, meaning their inclusions are visible under 10x magnification, but our gemstone buyers ensure they are not visible to the naked eye.
