## Why this stone

Every diamond at Ada is evaluated in person before it is listed. That in-person evaluation catches what grading reports and videos often miss, and filters out stones with cutting defects or unnatural color tones.

- 30-day returns by mail ($50 return label).
- Set it in a ring: [engagement ring settings](https://www.adadiamonds.com/lab-diamond-engagement-rings-all).
