NEED TO KNOW: DIAMOND CLARITY
Clarity, one of the essential 4C’s, refers to the qualitative metric grading the diamond’s visual appearance. It pertains to how clear and flawless or whether imperfections are visible in a diamond. The lesser the inclusions, the better the diamond clarity grade.
Inclusions are small imperfections inside diamonds, while blemishes are imperfections found on the diamond’s surface. Otherwise referred as “birthmarks,” these imperfections are tiny particles from other materials included during the formation of the diamond within the earth’s mantle. Feathers or tiny cracks may also appear on the diamond, creating an opaque surface.
A combination of numbers and letters scale is used to grade a diamond’s clarity. The rarest types of diamonds, and the most valuable, are those that are flawless or have little to almost no inclusion.
Clarity significantly impacts the overall value of a diamond. So, to reduce the overall purchase price of a significant diamond, you might want to compromise a little bit. Since inclusions are not easily recognisable by the naked eye, always ask to view the lower band selection prior to cementing your decision when it comes to grade.
DIAMOND CLARITY CHART
A number of items are taken into account when it comes to a diamond’s clarity grade. These include the visibility of blemishes or inclusions under specific magnifications, inclusion colour and sizes, the number of inclusions in the diamond and how they are positioned. This is because numerous inclusions are less brilliant because inclusions or blemishes interfere with the light’s path through the diamond.
When grading the diamond’s quality, diamonds are viewed top-down. From this specific position, anything invisible is easily ignored. Microscopes with 10x magnification along with loupes (or small magnifying glasses) are used when inspecting diamonds. The inspector notes down the inclusion, blemishes or feathers found on the diamond upon careful viewing. This creates a unique map of the diamond’s imperfections. Then, the diamond is identified and catalogued.
Clarity grades for diamonds range from FL to I3. I do not offer diamonds with a clarity grade of lower than SI2.
