The clarity of a diamond is an essential characteristic that reflects the presence of any inclusions or imperfections. Clarity is assessed using the GIA (Gemological Institute of America) scale, an authoritative organization in the diamond sector. The scale ranges from "Flawless" (with no imperfections visible at 10x magnification) to "Included" (with imperfections visible to the naked eye).

• Flawless (FL): Without visible imperfections, even at 10x magnification.
• Internally Flawless (IF): Without internal imperfections, but with small surface imperfections.
• Very, Very Slightly Included (VVS1 and VVS2): Small imperfections that are difficult to see at 10x magnification.
• Very Slightly Included (VS1 and VS2): Minor imperfections, visible only with closer attention.
• Slightly Included (SI1 and SI2): Imperfections visible under 10x magnification, but still difficult to see with the naked eye.
• Included (I1, I2 and I3): Imperfections visible to the naked eye.

The choice of purity depends on personal preferences and budget. A diamond with a higher clarity grade on the GIA scale may be more valuable, but the right balance between clarity, cut, color and carat is crucial to choosing the ideal diamond that suits your aesthetic preferences and individual needs.
