When a person decides to invest in a diamond, not many aspects bear more influence on the brilliance and the beauty than the cut. The AGS Ideal and GIA Excellent grades are among the best grading systems in the industry, and both are often compared with one another since they emphasize precision, fire, and sparkle in mind. So which is the one and the supreme?
This listicle demystifies the differences between these top-end cut qualities, so buyers can make a certain, sumptuous choice particularly when it comes to shopping on websites such as Rare Carat, a credible mainstay among on-line diamond vendors.
1. What Is the Cut: Why Is It Most Important to Learn?
The 4Cs (cut, color, clarity, and carat) mean that some believe cut is the most important in terms of maximizing the brilliance of a diamond. An ideally cut diamond reflects light both inside and outside the diamond to maximize fire, brilliance, and scintillation.
AGS Ideal- and GIA Excellent are the highest level of cut grading. Nevertheless, they are different with regard to their approaches and this presents significant differences to buyers.
Rare Carat works to demystify these nuances with free gemologist reviews and AI-powered value scoring so that buyers know precisely how the cut grade influences sparkle and price.
2. GIA Excellent Cut: Standard of the Industry
The Gemological Institute of America (GIA) is known around the world as one grading institute with strict standards. A diamond having a GIA Excellent Cut mark normally consists of high craftsmanship, best proportions, and brilliant sparkles.
What is Excellent about It?
- Outstanding performance with light
- Moderate sizes in order to have maximum glittering effect
- Symmetry and precision polish
The cut grade of GIA involves a number of optical measurements which include brightness, fire and the scintillation. Nevertheless, it has a wider system than AGS, whereby it sometimes covers diamonds that have a bit higher percentage differentiation under the Excellent category.
Shoppers on Rare Carat now find it easy to cross reference GIA Excellent cuts with other cut grades and price points across more than a million diamonds gathered with vetted suppliers.
3. AGS Ideal Cut: The Pinnacle of Precision
A 0 10 scale is applied by the American Gem Society (AGS), with 0 being the Ideal, which is the highest grade. They have their own proprietary grading formula that incorporates scientifically modeled light performance technology resulting in an analysis that is more precise than any other.
