Asscher Buyer Decision Matrix

Turn your preferences into a practical shopping profile—without pretending a quiz can grade a diamond

Updated: August 23, 2026Decision guideIndependent educational resource

What this tool does

This matrix does not “score” diamonds or pretend a questionnaire can certify beauty. It translates your priorities into an Asscher shopping profile: origin, size strategy, clarity/color starting points, setting direction, and the visual checks that deserve the most attention. It also warns when your stated preferences point more strongly toward another shape.

1. What matters most visually?
2. Budget approach
3. Origin preference
4. Inclusion sensitivity
5. Color sensitivity
6. Setting direction
7. Approximate center-stone target

Your Asscher buying profile

Use the profile in the right order

1) Set your quality/size target → 2) check real report numbers → 3) compare finalists → 4) choose the retailer with the inspection and return workflow you need.

Choose your priorities above, then build the profile.

How to use the result

Use the output as a starting filter, not as a substitute for inspecting the actual diamond. Asschers are fancy shapes without a standard GIA overall cut grade, so a clean report and tidy proportions do not guarantee an attractive windmill pattern or freedom from windowing.
