What is a Super Ideal Cut Diamond?

Diamonds received an upgrade in the early 1980s when De Beers decided to use a grading system called the Four C's that used previously unavailable information about a diamond to determine its quality. The Four C's were Clarity, Color, Cut, and Carat Weight. But in 2000, the Gemological Institute of America took another look at what people remembered about diamonds and evaluated how those things affected what people liked about diamonds. The research showed that while the Four C's were very accurate in describing the measurable quality of the diamond, they weren't so great at capturing what the consumer liked. So in 2006, the institute introduced a new version of the grading system called the 5 C's. The 5 C's added a new component to the grading system called Carat Weight. They also removed the "sensitive" grading scale for Color called the Color Grade.

So what exactly is a Carat weight? A carat is divided into 100 parts, so a 1 carat diamond is 100 parts, and the weight of the diamond would be 100 grams, or 3.5 ounces. So now, instead of the 100 grades of color, there is just one “ Very Slightly Included (VSI). That's why you'll see a diamond advertised as a 1-4 carat diamond. The 1 character in the 4 represents the 1 VSI and the 4 is the 4 C's of cut, polish, symmetry, and the crown height.

Anatomy of a Diamond

Anatomy of a diamond includes the following:

  • 4 C's of a Diamond
  • Cut
  • Clarity
  • Color
  • Carat weight

Diamonds are graded on these 4 criteria to determine its overall quality.

A diamond's cut determines how reflective and refractive the diamond is. It also determines the diamond's "brilliance" – also known as the amount of sparkle or fire. A poorly cut diamond may produce a lot of light, but the light is reflected in all directions, making the look of the diamond dull.

But the best cut diamonds reflect all the light that enters the diamond back to you in the manner that is most noticeable. This gives the diamond it's briliance.

Cut also affects the diamond's "star effect" or "sparkle". This is where the diamond sparkles like a star or shows extra flashes of light reflections. A well cut diamond should have over fifty "extra" sparks.

It’s important to remember that a well cut diamond does not mean a highly reflective diamond. The brilliance of a diamond is mainly affected by the cut.

GIA and AGS 0 Ideal Cut Grade

The Gemological Institute of America (GIA) and the American Gem Society (AGS) created a complex experimental method of evaluating and grading diamond cut using a specific scale. The result of this work was the creation of the 0 (Ideal) cut grade, commonly known as a super ideal cut diamond. If you’re willing to pay for the ultimate in diamond cut, then understanding these diamonds will be fundamental to choosing the right stone for your lifestyle.

Super ideal cut diamonds should be the most brilliant and costliest of any diamond. The GIA has been setting standards for the diamond grading and grading systems since the late 1920’s. When AGS was created in 1999 it expanded the original GIA diamond grading and set its own standard, which was the super ideal cut diamonds.

There’s more to the cut of a diamond than its shape, a diamond’s cut is arguably the most important element in determining a diamond’s quality and the price the customer ends up paying for the product.

What is Light Performance?

Light performance refers to a diamond's sparkle, which is mainly determined by its cut and polish rather than its carat size.

The grading scale used by the Gemological Institute of America (GIA) to grade the cut and polish of a diamond is a scale of Excellent, Very Good, and Good. It was initially believed that the cut had no effect on light performance radiating from a diamond, so the scale was separate from the one used for grading the cut of a diamond. However, the GIA has now found that the scale for light performance is similar to that of cut. The difference is a cut rating A colorless diamond can have a cut rating of Excellent, whereas a less colorless diamond can have a level of Good.

A diamond's cut and polish affect its sparkle in the same way light reflects from a mirror. The reflection of light on a mirror is whole-sphere reflection, which means the light reflects evenly across the surface of the mirror. A dull and unpolished mirror has a rough surface, which means light can scatter off it and the sparkle is reduced. Once the mirror is polished and made shiny, however, the reflection is enhanced, causing the object to look brighter, bigger, and clearer.

Are Super Ideal Cut Diamonds Expensive or Cheap?

When it comes to buying a diamond, size does matter, but not necessarily in size. If you don’t want to get into the technical details of cut, color, clarity, and other diamond characteristics, it may be easier to simply choose a cut. There are some cuts that are bigger than others, but that’s not the only way a cut is different.

A diamond’s shape, or cut, plays a significant role in how it looks and its overall value. If you’re interested in learning the difference between cuts and taking advantage of understanding the cut of your diamond, you’ll definitely want to read on. Here we’ll provide some valuable information to help you understand cuts and how they play a role in the price and value of your diamond.

The price of a diamond or any gem for that matter is influenced by a combination of factors, such as its popularity, demand, supply, and color, among many other factors.

A factor that can have the biggest influence on the value of a diamond is its cut. So, to get a better idea of how you can determine the value of your diamond by cut, you’ll want to understand the difference between cuts.

How To Buy A Super Ideal Cut Diamond?

The general public perceives a better quality, color, clarity, carat, and cut diamond as well as one that is greater in value. The problem is the general public does not know cut grades or the grading standards like the GIA (Gemological Institute of America) does. The GIA defines a super ideal cut diamond as one that has no noticeable blemishes such as inclusions or flaws. This type of such a diamond is one of the finest cuts possible. However, super ideal cut diamonds do not necessarily indicate high value and quality.

Diamond cut is the most critical of all 4 C's of diamonds. Just below 1% of all diamonds cut to the super ideal cut grade. Super ideal cut diamonds maintain their sparkle and are also the most durable. Perfect cut diamonds do not necessarily mean that they are more valuable than an excellent cut diamond. In fact, an excellent diamond cut can be more valuable than a superb one, in specific instances.

Ideal cut diamonds are the most brilliant and have the farthest refraction of white light. This makes them outstanding quality. The diamond market generally distributes diamonds on a scale that ranges from bad to good. Cut is the most important factor because it affects the price of the stone and visually determines the appeal of the diamond.

Super Ideal Cut Brands

Brilliant-cut diamonds are the most popular and most expensive. They are also the most commonly used for diamond wedding bands. Super ideal cut diamonds are not too far from brilliant-cut diamonds but their proportions differ just enough to make the cut less brilliant than a brilliant-cut diamond. In super ideal cut diamonds, the width of the crown (the top of the diamond) is be 1.5 to 2 percent larger and the depth (the bottom of the diamond) is 1.5 to 2 percent shallower than in a brilliant-cut diamond. Another term used for the super ideal cut diamond is the modified brilliant cut because the cut is still considered to be brilliant.

A great cut diamond is one with proportions that allow the maximum amount of light to be reflected from the flat surface of the diamond and then to be refracted through the top and bottom of the diamond.

Diamond cuts with deep and narrow facets will only reflect light through the top of the diamond whereas those with a shallow and wide crown will allow light through the sides and back of the diamond.

Diamonds with a shallow and wide crown will often have a dark window in the center of the top of the diamond because so little light can pass through the bottom.

Grading Reports and Certifications

When shopping for higher quality diamonds (AAA, VVS, and VS diamonds), you will quickly realize that certification is everything. You may find a diamond that is pretty, has a clean (eye visible) cut, and is priced well – but if it’s not certified, you can be sure that it’s not going to be of extraordinary quality.

The grading reports and certifications are vital because they help guarantee the precision of the cut and the high quality of the stone. The two most important certifications are: AGS (American Gem Society) and GIA (Gemological Institute of America).

The AGS grading certificate guarantees the quality of all the items on the stone, including its cut, clarity, carat, color, and finish. To get this certificate, the diamond must be submitted to a private stone grader and scrutinized in various ways to ensure it matches the criteria set on the certificate orders.

The GIA grading certificate is slightly different than the AGS as it is an international certificate. However, the process is similar to the AGS and the only difference lies in the stone’s identification number.

Where To Buy A Super Ideal Cut Diamond?

Super ideal cut diamonds are diamonds that have been cut to look more like the ideal cut diamond. They have 60 or more facets and a deep table. Due to the natural roughness of diamonds, most of them will have some inclusions.

Ideally, for these to be labeled as an ideal cut diamond, there should be no trace of inclusions. However, this is not possible because natural diamonds have a high probability of having inclusions. However, they should not be visible to the naked eye.

Super ideal cut diamonds are usually sold for a premium because of their attractive faces and the fact that they are natural diamonds. They are cut using modern technology to give you the best possible value for your money. In many cases they are cut to be a bigger size than the rough diamond.

Diamonds that have been cut using advanced technology are usually sold as super ideal or Super Ideal cut. The prices usually vary depending on the size, number of facets and the cut quality. Normally, the higher the quality of the cut the costlier it becomes.

You can also determine the value of your diamond by looking at its face-up size and its carat weight. It is a good idea to buy diamond ring with a super ideal cut even if you cannot afford to buy the biggest diamond you can find.

Diamonds are one of the most precious and desirable gemstones. They can also be costly. The cost of any diamond purchase depends on factors such as size, clarity, color, cut and shape.

Aside from the 4Cs of diamond terminology (cut, clarity, color and carat), one of the most important elements of a diamond is its shape. The most common diamond shape is round brilliant cut by far. But there are other cuts that are appropriate for different occasions. One of them is the ideal cut diamonds; either super ideal cut diamond or the standard ideal cut diamond.

Even if you don’t follow the trends, the majority of diamond shapes that you will find are the standard shapes: round, oval, princess, emerald, pear, marquise, heart, asscher and brilliant cuts. Some of the more contoured shapes are also very popular such as trillion, cushion, thumbprint, radiant, and baguette shapes. However every diamond shape does not have an ideal cut. While some shapes are based off of tradition, others are based on how the diamonds sparkle.
