The Ice on Fire difference is recognized by the American Gem Society (AGS) with its proprietary Light Performance Diamond Quality Document.
Every Ice on Fire Diamond receives the highest grade possible from the AGS, AGS Ideal 0 for cut, AGS Ideal 0 for light performance, AGS Ideal 0 for polish, AGS Ideal 0 for symmetry, but the Ice on Fire standard is far more precise than required by the AGS for a 0 Ideal cut grade.

Ice on Fire Diamonds are the result of extensive research conducted by the Gemological Institute of America (GIA) and the American Gem Society (AGS) concerning the behavior of light in a diamond. Building on this new understanding of the science of light return, Ice on Fire Diamonds are cut to precise angles and proportions to maximize the radiant light and sparkle emerging from the top of the gem.
Bigger, brighter and whiter, even compared to other Excellent and Ideal cuts, every Ice on Fire Diamond reaches the highest standard for cut, proportions, symmetry and light return from the GIA, AGS and Forevermark grading laboratories.
To ensure quality, value and peace of mind, each Ice on Fire diamond is inscribed with the GIA, AGS or Forevermark certificate number and the Ice on Fire diamond logo. Your Ice on Fire diamond may also be personalized with your own unique inscription.
While many diamonds are spread too shallow or cut too deep to retain weight from the original rough — at a dramatic sacrifice of potential Brilliance, Fire and Scintillation — a Ice on Fire Diamond is cut to precise angles and proportions to maximize the radiant light and sparkle that emerge from the top.
Diamonds cut to the precise portions will reflect and refract light in a vivid display of Brilliance, Scintillation and Fire.
Every Ice on Fire Diamond consistently delivers a bigger, brighter and whiter appearance. That’s because Ice on Fire has a narrower set of acceptable proportions than GIA Excellent and AGS Ideal cut diamonds. When you compare any two Ice on Fire Diamonds, you’ll notice how remarkably similar they are in proportion, polish and symmetry.
The precise angles of the Ice on Fire Diamond facets give it the largest diameter possible while efficiently reflecting light through the top. This allows the diamond to avoid light leakage and the “fisheye” effect. The Ice on Fire Diamond appears even larger than most other GIA Excellent and AGS Ideal cut diamonds.
When a diamond is cut to Ice on Fire proportions, the light entering from any direction is completely reflected through the top as white light (Brilliance) dispersed rainbow colors (Fire) and sparkling flashes (Scintillation). Inside the diamond, the facets act as mirrors — and it is the careful arrangement of these facets to achieve maximum Brilliance balanced by Fire and accented by Scintillation that is the secret to the luminous Ice on Fire Diamond.
The immense Brilliance of the Ice on Fire Diamond is the result of white light reflected through the top of the diamond. This is what allows a Ice on Fire Diamond to appear one or two color grades better than its actual GIA color classification.
Carat weight is the easiest aspect of a diamond to understand. One carat equals 200 milligrams in weight. 1.00 carat is sometimes expressed as 100 points (0.75 ct. = 75 points, 1/2 ct. = 50 points). Since Ice on FireDiamonds are of a superior cut, even a diamond of lesser weight maintains a higher value than inferior cuts.
Since diamonds form under tremendous heat and pressure, it is extremely rare to find a diamond that lacks any internal and external characteristics. The size, nature, location and amount of such inclusions determine a diamond’s clarity grade and affect its value.
Although many diamonds appear colorless, most have slight tones of yellow or brown. As these tones become less apparent and more colorless, the rarity and value of the diamond increases.
