The above diamonds have proportions and angles which are required for AGS’ excellent/ideal cut grade. The American Gem Society (AGS) has developed a diamond grading system which is based on light performance. This is by far the most effective way of determining the cut quality of a diamond as the system takes into account the very advanced research conducted by both AGS and its sister organization GIA. See The Fascinating Science of Diamond Fire.

The Selection Process

I assess diamonds for a number of factors. To be included in my recommendations a diamond must have:

The required angles according to potentially qualify for AGS’ ideal cut grade;
good contrast
optical precision
high quality diamond material;
good value;
no visible inclusions (eye-clean);

I only include a diamond I am confident the recipient will absolutely love.

The selection process involves (though is not limited to) keeping the search parameters within the ones I have published here:

Also worth reading to help understand my process and to know if and when the above parameters can be expanded, and what the consequences are:
