The clarity of the diamond to play other than the secondary imperfection rating on the level and inside of the stone. We call surface defects s, while other defects are initiates. Compared with the disadvantages that may be insufficient, the application can affect the beauty of the diamond, which are only applicable to certain systems.
When referring to inclusions, diamond specialists or gemologists often use the term "internal features" instead of a defect. It is the internal features that give the diamond its natural and unique character. You have to remember that diamonds with the least amount of impurities will receive the highest degree of purity - which is associated with a higher price
All diamonds are unique, not perfect. They are formed underground under the influence of great pressure and heat. Natural impurities and imperfections are inevitable and unique.
Diamond Transparency Includes 6 Categories with 11 degrees of transparency.
In 1953, Richard T. Liddicoat and colleagues proposed a diamond grading system and a transparency scale from the Gemmological Institute of America (GIA).
I1, I2, I3
Clarity diamonds having obvious inclusions that may be visible and affect the beauty
SI1, SI2
The inclusions are visible at 10x magnification
The SI2 inclusions can be felt, especially when viewed from the side
VS1, VS2
Minor inclusions, from difficult (VS1) to slightly easy (VS2), which are visible at 10x magnification
VVS1, VVS2
VVS diamonds have tiny inclusions that are practically invisible even at 10x magnification
Internally Flawless (IF) Diamonds
Some tiny surface blemishes can be seen under the microscope
Flawless (FL) Diamonds
No internal or external features
Less than 1% of all diamonds are of FL purity
A flawless diamond is extremely rare as it is almost impossible to find a 100% defect-free diamond
