Diamond Cut: A guide to choosing the best Diamond

Contrary to what most people think, the diamond cut doesn’t refer to a diamond’s shape. Instead, it refers to the diamond’s proportions, symmetry, and polish. best Diamond A diamond’s beauty is more reliant on its cut than any other factor.

There are three primary effects cut has on the diamond’s appearance, although they are extremely difficult to analyze and quantify. The first of these effects is brilliance. The brilliance refers to the brightness generated by merging all the white light reflections both from the surface and inside of a fully polished diamond.

The cut also affects the diamond’s fire. The fire is the disbandment of light into the colors of the visible color distribution, which is visible as color flashes. The scintillation, which refers to the light and dark sparkle that appears when a light source or diamond is moved is also an effect of the diamond’s cut. This article will teach you all you need to know about a diamond’s cut and how it relates to a diamond’s price.

Cut Scale

1. Fair & Poor

Similar to school grades, diamonds with notable light leakage are graded as either fair or poor. This set of jewels are more likely to emit a noticeable amount of light from being too deep or shallow. These diamonds possess little brilliance and are not very physically attractive. Diamonds with a fair or poor cut usually don’t meet the Clatity’s minimum light performance benchmark. Diamonds that fall into this cut class represent the top 35% of gem-quality diamonds. Given that budget isn’t an issue, you should generally avoid these types of diamonds as they don’t produce sparkling jewels.

2. Very good

Diamonds with very good cuts reveal almost all of their potential is very brilliant with little light leakage. Most diamonds are deliberately cut to produce the best possible grade, which will lead to significant improvement in the gems’ other features like clarity, color, or carat. 15% of all top gemstone quality diamonds are of the Very Good cut, and they make an excellent choice if you have a target of value maximization with a good budget.

3. Good

Diamonds with a Good cut have a high percentage of sparkle, and they capture light. Although diamonds with this cut quality aren’t perfect because they may have some light leakages, they still shine very brightly. These diamonds can differ significantly in size. They can either be very small or very large in measurement compared to perfectly cut diamonds of the same shape.

Diamonds can be cut into Good proportions solely because of achieving a specific style or look for the jewel. 25% of top diamonds fall into the Good cut grade. Good cut diamonds are a mix of value and size. However, the best bet would be to involve a gemologist for a thorough study of the specific diamond before you make your decision. best Diamond

4. Excellent

As the name implies, this is the highest and best diamond cut grade, and it represents the top diamonds around the globe. Diamonds that fall into the excellent cut grade are precisely and masterfully crafted to provide the best possible sparkle and brilliance that can be possibly obtained in a diamond.
There is little to no light leakage in most cases as light seamlessly penetrates the diamond.

This exclusive cut represents only 3% of diamonds. Excellent cut diamonds are seeing expanding upgrades being implemented in their manufacturing technology. They are always a perfect choice irrespective of their shape or size if you can afford to shell out the exorbitant price.

Parts of a Diamond

  • Table

It’s the largest and topmost facet of a diamond through which light penetrates and escapes with sparkle and fire. The perfect range for the table facet in a round-cut diamond varies from 54% to 61%. Larger tables can potentially make a diamond look larger because the reflection rather than retraction may be greater. best Diamond

  • Depth

This is the distance from the diamond’s table to its culet. It is an important characteristic in determining the cut grade of a diamond. Diamonds that have a large distance from the table to the culet are prone to slight leakage. Diamonds with a deeper cut will appear smaller than their counterparts with the same carat weight. This is because the diamond’s depth holds the carat weight.

While shallow-cut diamonds will experience a slight leakage. Shallow cut diamonds tend to look larger than deeper diamonds because the carat weights are pushed to the sides of the diamond, giving it more surface area. A shallower diamond is great, but the tradeoff is the possibility of a light leakage or sparkle. The ideal range for a round-cut diamond is between 59% – 63%.

  • Crown

This is the top part of the diamond that sits above the girdle. It has that particular name because it is at the height of the diamond and its structure resembles a crown from the ground up. It is through this part of the diamond that light enters and escapes. The crown must have a perfect angle to enhance light reflection or refraction for maximum sparkle and brilliance. A crown with a shallow angle looks like a flat top and increases light leakage. Heavy or steep crown angle reduces light penetration and minimizes the diamond’s sparkle.The ideal crown angle for a round diamond is between 32.5 – 35 degrees. best Diamond

  • Pavilion

This is the base part of the diamond located below the girdle. The diamond’s pavilion must be correctly angled and faceted to refract light, similar to the crown. Immediately light goes into the crown, the pavilion reflects light to the eye, creating a sparkle effect in the process. If angles are too deep or too shallow in the pavilion, the light will fall through. Sparkle is just the bouncing back of the light. If this doesn’t happen, the sparkle will be lost. The ideal pavilion angle for a round diamond is 40 – 41.6 degrees.

  • Culet

The culet is the foundation of the diamond. It’s at this point the faceting of the diamond meets in the center below the table to seal it off, preventing light from falling through. Most point culets are graded none. A diamond that has medium or light culets tend to suffer from light leak and are mostly found in old fashioned European cut diamonds. Normally, diamonds should be very hard to chip. However, culet can chip from blunt impact or trauma due to its thin nature.

  • Girdle

The diamond’s girdle is the thin part between the crown and pavilion. It is the widest pint of a diamond and can either be polished, unpolished, or faceted. Most diamonds nowadays have slightly polished or faceted girdles. The girdle’s thickness directly affects the diamond’s cut grade, and most girdle range comes in thin or slightly thick. When girdles are too thin, they can break during the setting process and very thick girdles reduce their sparkle due to the girdle reflection they create in them. best Diamond


The color and size aren’t all you should consider about a diamond. Sometimes, the cut quality will be the deciding factor in a diamond purchase.
If you don’t know how else to get a discount for that diamond, why not bring up the quality of the cut?
