Diamond Clarity Spans 6 Categories With A Total Of 11 Clarity Grades
İçinde 1953, Richard T. Liddicoat and colleagues established the Gemological Institute of America (AİLE) diamond grading system and clarity scale. The GIA diamond grading scale is divided into 6 categories and 11 diamond clarity grades.

I1, I2, I3 Included Diamonds
I clarity diamonds have obvious inclusions that are likely to be visible and impact beauty
Blue Nile does not sell I clarity grade loose diamonds for engagement ring designs
Blue Nile does offer a limited selection of jewelry preset with I1 diamonds
SI1, SI2 Slightly Included (SI) Elmas
Inclusions are noticeable at 10x magnification
If eye clean, SI diamonds are often the best value
SI2 inclusions may be detectable to a keen unaided eye, especially when viewed from the side
VS1, VS2 Very Slightly Included (VS) Elmas
Minor inclusions ranging from difficult (VS1) to somewhat easy (VS2) to see at 10x magnification
Great value; Blue Nile’s most popular diamond clarity
VVS1, VVS2 Very, Çok biraz dahil (VVS) Elmas
VVS diamonds have minuscule inclusions that are difficult even for trained eyes to see under 10x magnification
VVS clarity is rare and results in an eye clean appearance
Characteristics are minuscule and difficult to see under 10x magnification, even to a trained eye
Internally Flawless (EĞER) Elmas
Some small surface blemishes may be visible under a microscope on IF diamonds
IF diamonds have no inclusions within the stone, only surface characteristics set the grade
Visually eye clean
Kusursuz (Fl) Elmas
No internal or external characteristics
Less than 1% of all diamonds are FL clarity
A flawless diamond is incredibly rare because it’s nearly impossible to find a diamond 100% free of inclusions
