Three Rows Worth a Sentence
Grading
MiaDonna's FAQ states that "all of our graded diamonds come with a complimentary diamond grading report from the International Gemological Institute (IGI) or the Gemological Institute of America (GIA)" and its solitaire listing publishes three quality tiers — F-VS2, E-VS1 and D-VVS2 — while Brilliant Earth's lab grown diamond search carries a Report filter listing IGI, GIA, GCAL and HRD, read from an archived copy dated 7 September 2026.
Every Beyond Carat diamond is graded by IGI before it ships, and the report travels with the ring at no extra charge. Our published band is D, E or F colour, VVS or VS clarity, and Excellent cut on every piece, at every carat weight. We are IGI-only; if you specifically want a GIA report, our IGI vs GIA page explains the difference. Because the published band is the same on every piece, the report in the box says the same thing on a half-carat stud as on a three-carat solitaire, and we will open it on screen with you on a free video or phone consultation.

Warranty
MiaDonna's warranty page publishes a Lifetime Manufacturing Warranty on every purchase, running from the date of purchase and covering lab-grown diamonds, lab-created gemstones and the craftsmanship of the jewelry, while Brilliant Earth's archived online shopping page dated 28 August 2026 publishes a free lifetime warranty against manufacturing defects on all Brilliant Earth fine jewelry.
