Result of AGSL ray tracing a 3D model of the diamond scientifically evaluating brightness, contrast, fire and leakage. For more details see our page on Light Performance Cut Grading.
Cut
Cut refers to Cut Quality, the most important aspect of diamond beauty. It is a measure of craftsmanship that involves the proportions, facet placement and finish of the diamond. For more details see our page on AGS Cut Grading.
Polish
The aspect of finish related to the quality of facet flatness and luster. Each facet should be polished to a mirror finish.
Symmetry
Also known as ‘meet point’ symmetry, describes the degree to which contiguous facets meet precisely at the proper places all around the diamond.
Fluorescence
Some diamonds react to strong ultraviolet light waves by emitting light, usually blue, in a process known as photoluminescence. More information can be found on our fluorescence page.
Eye-Clean
The ability or inability to see inclusions in a diamond with the naked eye. Our definition of eye-clean: No inclusions visible to the naked eye of a person with 20/20 vision when viewing the diamond in the face-up position at a distance of approximately 10 inches under normal overhead lighting. Distance, lighting and human vision all influence this judgment.
Culet
The very bottom of the pavilion side of a brilliant style diamond. It is usually pointed, but can have a flat facet placed on it that can range from very small to large.

Brittany was the best during my purchase. Her response times via both email and phone are indescribable. Purchasing an engagement ring trying to ensure your money is well spent and trying very hard to get it right as selecting the ring for your future wife can be taxing on the man. She went way above and beyond, and all I can say is she helped me nail it. 100 percent perfection, my future bride is ecstatic! The proposal was beautiful and the look on her face as she saw the ring in the little beach chair positioned on the starfish as she read the message in the bottle, was one I'll never forget. She was immediately taken by the ring, such a huge smile on her face, has told me a hundred times how beautiful it is and how much she loves it and how I just nailed it from the ring to the presentation. I won't lie, I've glanced at her hand so many times and it is so perfect on her hand. And Oh My God...the sparkle on the beach I even saw it sparkle from across the room at a restaurant as I was walking back. So indescribably happy, it was all perfect! Thank you for all of your help and the fantastic communication! A fella gets anxious with all of this, but you made it easy. Tks Brittany!!

From the very beginning, Brittany demonstrated a remarkable level of professionalism, attention to detail, and a genuine willingness to go above and beyond. Her responsiveness and care made the entire experience smooth, enjoyable, and stress-free. It’s rare to find someone so committed to excellence and so attentive to every need—she truly embodies the spirit of outstanding customer service. Thank you, Brittany, for making this experience so memorable. Whiteflash is lucky to have you!
