Personal Note From Natural Gems Belgium:

This Sapphire consists out of 3 colors being blue green and yellow. 
The gemstone is very clean and would be in most cases considered IF, but we prefer saying VVS1 to IF since every natural gemstone has inclusions even if a larger magnification is needed.
Cut grade is good, symmery is good, clarity is very good to excellent, polish is good to very good. resulting in good luster.
Weonly declare gemstones larger then 2 ct as AAA  grade, otherwise this would have been one.
