What Is Diamond Clarity?
The assessment of minor flaws on the surface and within the stone is known as diamond clarity. Internal imperfections are known as inclusions, whereas surface flaws are known as blemishes. Most inclusions aren’t visible to the naked eye; thus, they have no effect on a diamond’s beauty. Gemologists frequently refer to inclusions as “internal features” rather than defects when discussing them. The character of a natural diamond is determined by its internal features. It’s also worth noting that diamonds with the fewest and smallest inclusions obtain the highest clarity grading and, as a result, command higher prices.
When a diamond is lighted, clarity impacts how it glows and appears, and fewer inclusions indicate the diamond will sparkle brighter. Keep in mind that no diamond is completely pure when evaluating the best clarity for it. The closer it gets to purity, though, the more evident it becomes.
The Clarity Factors in Diamonds
Size: The lower the clarity grade, the larger or more apparent a feature is.
Number: The number of plainly visible qualities is represented by this number. The greater the clarity rating, the fewer the features.
Position: What does a characteristic’s location mean? Is it near a pavilion and under the table (the most visible)? Inclusions become reflectors in this position, affecting the clarity grade more significantly.
Nature: The type of inclusion and its impact on durability are discussed under the nature of a diamond feature.
Color and relief: Color and relief are a measure of how easily a feature can be seen, or how much contrast there is between the feature and the surrounding diamond.
Diamond Clarity Is Divided into Six Categories, Totaling 11 Clarity Grades.
The Gemological Institute of America (GIA) diamond grading system and clarity scale were established by Richard T. Liddicoat and colleagues in 1953. The GIA diamond grading scale has six categories and eleven clarity grades.
Diamonds I1, I2, and I3
- I clarity diamonds contain apparent inclusions that detract from their attractiveness.
Slightly Included (SI) Diamonds, SI1, SI2
- At a magnification of 10x, inclusions are visible.
- SI diamonds are frequently the best value if they are eye clean.
- SI2 inclusions can sometimes be seen with the naked eye, especially when viewed from the side.
Diamonds (VS) VS1, VS2 Very Slightly Included
- At 10x magnification, minor inclusions range from challenging (VS1) to moderately easy (VS2) to see
- Great price/value
VVS1 and VVS2 diamonds are very, very slightly included (VVS).
- Under 10x magnification, even trained eyes can’t discern the microscopic inclusions in VVS diamonds.
- VVS clarity is uncommon and gives the appearance of a clean eye.
- Even to a skilled eye, characteristics are small and difficult to notice under 10x magnification.
Internally Flawless (IF) Diamonds
- Under a microscope, some minor surface imperfections on IF diamonds may be observed.
- If there are no inclusions in a diamond, the grade is determined solely by its surface qualities.
- Visually pleasing
Diamonds that are Flawless (FL).
- There are no visible or internal characteristics.
- FL clarity diamonds make little less than 1% of all diamonds.
- It’s very impossible to find a diamond that is completely devoid of inclusions, thus a perfect diamond is quite unusual.
