Practically all diamonds contain naturally occurring internal characteristics called inclusions. The size, nature, location and amount of inclusions determine a diamonds clarity grade and affect the cost.

Under the scrutiny of a jeweler's 10x magnifying loupe or microscope, the natural inclusions may be seen. These are nature's birthmarks, and they may look like tiny crystals, clouds or feathers.

Major inclusions such as I1, I2, I3 can interfere with the path of light that travels through a diamond, diminishing its brilliance and sparkle and therefore its value.

GIA Clarity FL Flawless Completely flawless both internal and external at 10X magnification with well trained eyes. IF Internal Flawless Minor surface blemished. Free from internal inclusions at 10X magnification with trained eyes. VVS1 WS2 Very Small Inclusions Very difficult to see inclusions at 10X magnification with trained eyes. VS1 VS2 Very Small Inclusions Difficult to see inclusions at 10X magnification with trained eyes. SI1 SI2 Small Inclusions Somewhat easy to see the inclusions at 10x magnification with well trained eyes. I1 I2 I3 Imperfect Eye visible inclusions. Inclusions heavy with naked eyes.

Most diamonds, although appearing colorless, actually have slight tones of yellow or brown. As these tones become more easily apparent, the rarity and the cost decrease.

Diamonds are graded by color, starting at D and moving through the alphabet to Z.

Evaluationg a diamond's color for grading purposes is done by mesuring the degree to which a diamond approaches colorlessness.

Although it is difficult for the untrained eye to see these minor variations, a jeweler can help demonstate them by showing you diamonds side by side.

Diamonds graded as D, E, and F are more expensive because they are more rare. The popular grades of diamonds are G, H and I, J, K are less popular. If you want to see how different color diamonds look under a master Color Grading set, please visit our store or contact us to make an appoitment.
