Almost all diamonds contain very tiny natural birthmarks known as inclusions. To determine a diamond's clarity, an expert studies it under 10x power magnification. In addition to internal inclusions, surface irregularities are referred to as blemishes. These two categories of imperfections-inclusions (internal) and blemishes (external)-make up clarity.

The fewer the imperfections, the rarer and more valuable the diamond. Many inclusions are not discernable to the naked eye and require magnification to become apparent. A laboratory-certified clarity rating of SI2 represents the point at which inclusions are technically not apparent to the average naked eye.

Contrary to popular belief, higher clarity does not always mean more beautiful. If the inclusions are not visible to the naked eye, a higher clarity does not really improve the appearance of a diamond but rather the rarity and price. A higher clarity is more desirable and valuable, but knowing that you have selected the right clarity for the right reasons is most important. We recommend a clarity of SI2 or better.

Clarity is graded using a very precise and complex method of evaluating the size, location,
and visibility of inclusions. The diagrams to the right show a top view of a round diamond.
The inclusions, shown in red, are an approximate example for each clarity rating. The plotted inclusions may not be actual size for display purposes. Remember, the inclusions depicted in red are not visible to the average naked eye until the I1-I3 clarities. Below is the technical clarity scale with a description of each term.

FLAWLESS. Shows no inclusions or blemishes of any sorts under 10x magnification
INTERNALLY FLALESS. Has no inclusions when examined by an experienced grader using 10x magnification.
VERY VERY SLIGHTLY INCLUDED. Designated by VVS1 or VVS2. Contains tiny inclusions when examined by an experienced grader using 10x magnification.
VERY SLIGHTLY INCLUDED. Contains very small inclusions such as crystals, clouds, or feathers when examined by an experienced grader using 10x magnification
SLIGHTLY INCLUDED. designated by SI1 or SI2. Contains small inclusions (clouds, knots, included crystals, feathers and cavities) that are noticeable when examined by an experienced grader using 10x magnification.
INCLUDED. Contains inclusions (large feathers, large included crystals etc…) that can be seen with unaided eye. Mostly sold with discount jewelry in chain stores.
