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. The recommendations I make are all diamonds which would potentially receive an Excellent cut grade as an absolute minimum. For more on how angles affect a diamond’s brilliance see The Fascinating Science of Diamond Fire.
The Selection Process
I assess diamonds for a number of factors. For a diamond to be included in my recommendations it must have:
- The required angles according to potentially qualify for AGS’ ideal or excellent cut grade;
- good contrast
- optical precision
- high quality diamond material;
- good value;
- must be deemed eye-clean by me;
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:
