I1 Clarity Diamonds

At Brilliance, we offer certified diamonds with a clarity rating of FL (Flawless) to I1 (Included) to ensure the largest selection. I1 clarity diamonds contain very obvious inclusions under 10x magnification. Inclusions may be noticeable to the unaided eye and might also impede transparency and affect brilliance. Those seeking a bigger carat weight at a low price will choose a diamond of this quality.

Diamond Clarity

Inclusions are nature's birthmarks, the characteristics - or lack thereof - that make every diamond unique. The fewer inclusions and blemishes a loose diamond has, the better its clarity, and the more rare and valuable it is. Flawless diamonds containing no inclusions are extremely rare and consequently more expensive. Diamonds that contain flaws that are undetectable without magnification make up the majority of certified diamonds.

Clarity Scale

Diamond Clarity is graded in certified diamonds on a scale ranging from FL (flawless) to I3 (included) and is based on the size, number, and location of characteristics in a diamond.

  • FL, IF (Flawless, Internally Flawless): No internal or external inclusions when viewed with 10x magnification. Internally Flawless diamonds may contain external characteristics.
  • VVS1, VVS2 (Very Very Slightly Included): Contains minute inclusions that are extremely difficult to locate under 10x magnification.
  • VS1, VS2 (Very Slightly Included): Contains minute inclusions, such as clouds, crystals, or feathers, which are difficult to locate with 10x magnification.
  • SI1, SI2, SI3 (Slightly Included): Noticeable inclusions under 10x magnification, including clouds, knots, crystals, cavities, and feathers.
  • I1, I2, I3 (Included): Contains very obvious inclusions under 10x magnification. Usually can be seen with the naked eye. Clarity might also impede transparency and affect brilliance.

Inclusions are made up of internal and external characteristics. Internal characteristics are called inclusions and the most common inclusions are crystals, clouds, and feathers. External characteristics, or surface irregularities, are called blemishes. As most inclusions are invisible to the unaided eye, gemologists use a ten-power (10x) microscope to rate clarity.
