Diamond Clarity

Diamonds are graded for clarity under 10x loupe magnification. Grades range from Flawless (diamonds which are completely free of blemishes and inclusions), to Included 3 (diamonds which possess large, heavy blemishes and inclusions that are visible to the naked eye).
  • F
    Flawless: No internal or external flaws. Extremely rare.
  • IF
    Internally Flawless: no internal flaws, but some surface flaws. Very rare.
  • VVS1-VVS2
    Very Very Slightly Included (two grades). Minute inclusions very difficult to detect under 10x magnification by a trained gemologist.
  • VS1-VS2
    Very Slightly Included (two grades). Minute inclusions seen only with difficulty under 10x magnification.
  • SI1-SI2
    Slightly Included (two grades). Minute inclusions more easily detected under 10x magnification.

  • I1-I2-I3
    Included (three grades). Inclusions visible under 10x magnification AS WELL AS to the human eye. We do not recommend buying diamonds in any of these grades.

    While the presence of these clarity characteristics (inclusions and blemishes) do lower the clarity grade of a diamond, they can also be viewed as proof of a diamond's identity. GIA certificates include what is known as a "plot" of a diamond's inclusions -- think of it as a "diamond fingerprint." Since no two diamonds are exactly the same, comparing the uniqueness of your diamond's clarity characteristics with the plot provided on the diamond certificate offers assurance that the diamond you pay for is the same diamond you receive.

Round Brilliant Diamond Shape

round brilliant diamond In contemporary times, the round brilliant diamond has become the most popular diamond shape for the engagement ring.

But diamond cutters have been studying and refining the round cut for much longer than the current popularity -- and diamond cutters now use advanced theories of light behavior and precise mathematical calculations to optimize the fire of a round diamond.

Because of the popularity of round diamonds, all diamond stores are well-stocked with round diamonds, providing customers with the greatest range of flexibility in terms of balancing cost versus quality. In other words, whether you are on a limited budget or the "sky's the limit", you will likely be able to find a suitable Round Brilliant Diamond in your price range at most stores.

Choosing a Round Brilliant Diamond

For the round brilliant diamond, selecting the highest quality cut you can comfortably afford is important. For those that can afford it, "Ideal" or "Signature Ideal" is the perfect choice, but gorgeous diamonds can still be purchased with less demanding cut grades.

Our minimum recommendations for buying round brilliant cut diamonds are as follows (please remember these recommendations are opinion only, and your tastes may vary):

  • Cut: Good
  • Color: G
  • Clarity: SI2
  • Depth Percentage: 57-65%
  • Table: 51-64%
