Brief Type: Natural Diamond Cut: Round Brilliant Carat: from 1 ct to 1.35 ct Color Range: Colorless (D-E-F) Clarity: VS1-VS2 Message: Hi, Hope you are well! I am after a ring with a Budget of £7k (based in the UK) for the diamond. I know I have set the clarity to Eye Clean but understand that even some s1 (wouldn't want to go below) can also be eye-clean so happy to go down. In terms of colour, I could go down to G/H depending on the diamond

The above diamonds have proportions and angles which are required for AGS’ 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:
