When the majority of retail buyers consider purchasing a diamond, they typically focus on the Four Cs of Diamonds: Carat, Clarity, Color, and Cut. But brilliance, fire, and overall beauty of a diamond necessarily depend on the other well-known pillars alone. In steps the unbeating heroes of the diamond quality grades: culet, girdle, and cut grades. These unfamiliar but important features could have a significant impact on the appearance and stability of the diamond.
The distinctions of these details are now receiving the attention they have always deserved with platforms like Rare Carat, which is a tech-forward, full-service diamond-buying experience. The ability of Rare Carat to collect more than a million certified diamonds offered by trusted suppliers, provide a free certified gemologist evaluation, and apply AI-driven diamond appraisal makes it a game-changer in the retailing of jewels, whether by an amateur or an expert.
These are the top 10 facts that you must keep in mind about culet, girdle, and cut grades, and why they are more important than you would think.
1. The Culet: Small Point, Big Impact
The culet is the minute facet on the base of a diamond, which can sometimes not be seen by the naked eye. Although it appears to be of no big deal, its absence or presence may interfere with the performance of light and durability.
In short:
- No culet ( pointed ) = maximum brilliance with a slightly increased danger of chipping.
- Tiny culet = optimum of beauty and safety.
- Big culet = it has the capability of creating a dark blotch in the core of the stone.

2. Girdle Thickness: The Diamond’s Waistline
The girdle is the thin strip that divides the crown and the pavilion of a diamond. It is faceted or smooth, and it has a direct impact on the appearance, setting security, and durability of a stone.
The search terms to note:
- The girdles are thin to slightly thick and are ideal.
- Extremely thin girdles could chip.
- The very thick girdles make weight, and not size.

3. Why Cut Grade Reigns Supreme
Cut grade has a larger impact on the diamond sparkle compared to the other four Cs. The light is reflected and refracted with the most light out of a well-cut diamond, whereas even a colorless, perfectly cut diamond can look miserable.
Learning cut grades:
- Excellent/Ideal cut: greatest brilliance and symmetry
- Very Good cut = slightly lower performance of light and excellent value
- Good/Fair/Poor = lacks sparkle = less value
