When a diamond is being formed, microscopic inclusions and blemishes occur – those are the birthmarks of the stone, giving its uniqueness and beauty – The Clarity grade, in this case, evaluate them, measuring its level of physical integrity, its “cleanliness”: internally and externally. Inclusions and blemishes should not distract from the brilliance or fire of a Diamond, but it should be eye clean.

  • Internal - can affect the degree of erosion and it is difficult to fix, as it involves a lot of weight loss, so it must be checked carefully. Usually have luster and thickness, easy to see at 10x magnifying glass.

  • External - easier to solve and does not involve loss of much weight, but are commonly lackluster or colorless, being difficult to find.
