Clarity in Natural Sapphires

Natural sapphires are formed under intense heat and pressure, and as a result, often display internal and external features known as inclusions and blemishes. These characteristics are not defects. They are vital indicators of natural origin and can help gemmologists assess the gemstone’s variety, provenance and treatment history.

Unlike diamonds, coloured gemstones are not graded using a global clarity scale. However, the Gemological Institute of America (GIA) classifies sapphires as Type II gemstones, meaning they typically form with some level of inclusions. Sapphires with no inclusions at all may require further assessment to confirm natural origin.

Each sapphire is evaluated under 10x magnification and assessed in natural daylight for clarity, durability and overall visual appeal.

Clarity Scale:

Eye Clean: No inclusions visible to the naked eye, though some may be detectable under 10x magnification or on close inspection.
Very, Very Slight Inclusions: Extremely small inclusions that are typically only visible from certain side angles.
Very Slight Inclusions: Small internal features that are noticeable upon close inspection.
Slight Inclusions: Inclusions that are clearly visible without magnification.
Apparent Inclusions: Inclusions that are obvious and easily seen.

Please note that gemstone appearance can vary depending on lighting. Shifts in tone, contrast and brilliance are natural characteristics of each stone’s cut and faceting.
