Understanding Clarity grades to pricing.
Below is a handy guide showing you different types of grades. This grading standard is set by the Gemological Institute of America, GIA, who founded the Clarity scale of which certified diamonds are measured: https://www.gia.edu/gia-about/4cs-clarity. Our illustrations below are based on this scale and from which our own diamonds are measured and certified. Please note the red marks on the diamonds are not to scale. In fact you wont often see the defects with the naked eye. We have enhanced this to give you a better idea of how they are graded. When diamonds are graded they are magnified at 10x power using a magnification loop.
FL – Flawless is the rarest of diamond finds. If you select this kind of grade when in buying mode, expect the price to be very expensive, as this represents perfection. This Diamond Clarity has no inclusions or blemishes of any sort visible to a skilled diamond grader using 10x magnification.
IF – Internally Flawless is also considered quite rare. The price point is still expensive but should be less expensive than a flawless diamond. This Diamond has no inclusions and only blemishes are visible to a skilled grader using 10x magnification.
VVS1 – VVS2 – Very, very slight inclusion. The price point should be less expensive when compared to a FL and IF diamond grade.This Diamond clarity has inclusions but they difficult for a skilled grader to see using 10x magnification.
VS1 – VS2 – Very slight inclusion. A skill grader should be able to see inclusions in the diamond. With this in mind the price point is lowered but the diamond quality is still very high. Inclusions in this Diamond are noticeable to a skilled grader using 10x magnification.
SI – Small Inclusion. The inclusions within the diamonds are now slightly heaver and easy to see, still only by a skilled grader using 10x magnification. This makes the price point affordable when compared to a FL graded diamond. However, this still makes for a stunning diamond and will look great on a diamond pendant or engagement ring purchase. These diamonds are spotless to the naked eye.
This scale was created to standardise the scale on an international level so that all dealers could grade their diamonds to an exacting standards and provide confidence to the buy of their investment.
