Reading your number

What to do with the range

A quote inside the range is normal retail. Compare two or three certified stones at the same spec and pick on cut quality, not on a $100 difference.

A quote well above the range needs a reason you can verify: a designer setting, exceptional cut grades, or a brand premium you've decided is worth paying. "Our stones are hand-selected" is not a reason; every seller says it.

A quote well below the range is where caution pays. Check the certificate (GIA or IGI, and verify the report number on the issuer's site), look for strong fluorescence, poor cut grades, or clarity that's "SI2" on paper and cloudy in person. Cheap has a cause; your job is to find it before you pay.
