What you see immediately and practically at the same time is the quality of Cut

• Cut: EX or VG
• Polish: EX or VG
• Symmetry: EX or VG
= Ideal Cut: This is giving the sparkle, the brightness, the shining and the brilliance of a diamond.

• 4th C
Reject very thin girdle. By very thin girdle the diamond sooner or later will break!
What you see as fifth important element is the Color
You can see the difference if a diamond is snow white or yellowish or a fancy color such as overpriced pinks.
Snow white is giving the most beautiful effect in combination with the brightness, the shining and the brilliance.
Pure white has the maximum brightness, and pure black the minimum brightness.
How blue fluorescence is in a positive way influencing brilliance, color and clarity
The clarity of a diamond is less important.
Inclusions are the signature of the diamond.
All what you do not see by naked eye is invisible, do NOT pay for !
It is the visible clarity by nacked eye who is important!
Do not pay for invisible inclusions!
If you look under microscope and you will find full of natural inclusions giving you the guarantee of authenticity.
