FINDER: GRADES
Grade finder
The minimum color and clarity actually worth paying for, which depends on shape, metal, and whether you can inspect the stone. Everything above these grades is money spent on a secret.
These are eye-clean, looks-white thresholds for a ring viewed at human distance, not lab distance.
Why thresholds, not maximums
Grades are a ladder, but your eyes are a cliff: below a certain grade flaws show, above it nothing changes except the invoice. The finder hands you the cliff edge for your combination, and the difference between that and the top of the ladder is honeymoon money.
