My Grading System
EC = Eye Clean
This is the best grade that I will give a stone. It means that with the naked eye the gemstone appears to be clean with no visible inclusions or flaws.
It is possible that there might be very minute inclusions which I simply have not seen. In the industry there is one higher grade : Loupe Clean. This is using a special X10 magnifying glass to inspect the stone and finding no inclusions or flaws.
VSI = Very Slightly Included
I usually apply this grading to a gemstone if it has only one or two very small/minor inclusions. This is usually a single spot, bubble, needle or veil that is almost impossible to see under normal conditions. The overall beauty of the gemstone is not affected at all.
SI = Slightly Included
This gemstone may have slightly more minor inclusions. None of them detract from the overall beauty of the stone in a noticable manner. Generally these inclusions would be hard to detect once the stone has been set.
I = Included
An included gemstone has multiple inclusions of the same or varied type. These are noticable and must be considered. Setting the stone will not hide the inclusions.
