Why Pay More for a GIA Certified Diamond or Certified Diamonds vs Non-Certified Diamonds or Should I Pay More for a Certified Diamond?


Does it really matter if you buy a GIA certified diamond or settle for a gem, which is not certified? Should I really pay more for certified diamonds? It all depends on what you want.


A diamond's sparkle may catch your eye. If your future wife really loves it, you will probably pay anything to make her happy. But, should you go with just any diamond or buy a GIA-certified diamond? Here are the reasons why it makes sense to buy a GIA-certified diamond.


Quality Assurance Benchmarks: Avoid Fakes

You have heard the saying - "A diamond is a girl's best friend." 


A diamond is both an investment in your relationship and your wealth portfolio. 

See, the diamond is the hardest gem on earth and is more expensive due to its scarcity. 

When you start to look at different diamonds, you might wonder why the certified diamonds might be more expensive than the non-certified diamonds.

To explain, let's start with a simple question, "Can you tell the difference between diamond quality levels?" Let's be honest - the "average person simply cannot tell the difference between a quality expensive stone and a fake piece of junk." 

No need to worry - for those who want a second opinion, they might turn to a grading service, like the trustworthy Gemological Institute of America (GIA).


There Are Many Diamond Grading Services

Let us not mince words, there are many grading systems in the world, but not many can compare to the Gemological Institute of America (GIA).


Well, they literally wrote the book on grading diamonds, by creating the 4 C’s “International Diamond Grading System:”

  1. Clarity
  2. Color
  3. Cut
  4. Carat Weight


They are independent and unbiased. “They don’t have a dog in the hunt.” Their reputation is based on providing an accurate assessment of diamond quality, using scientific tools and standards to give you an unbiased rating. 

When the royals grade their diamonds, this is whom they call.

With this certification, you have more certainty over quality and can better understand price point differences.

A non-certified stone is a "shot in the dark." You really don't know what you are getting.

Certification Adds Certainty, Verification and Authentication

"Why do you give a diamond ring, pendant or necklace to your future wife?" 

Because you are making a commitment to her. This might be considered a down payment on your love. This diamond might be placed in her jewelry box or a safe deposit box. When you purchase a high value gem, it is an investment; grading firms can verify and authenticate the quality level of the diamond. 

Certification can "literally mean thousands of dollars of a difference in price."

You could compare a certified diamond to a background check on an employee - this will authenticate the information provided by an individual on an application. Some even have a laser-inscribed serial number on each certified stone, to assure that the right grade goes to the right stone.


Understanding Pricing Differential and the 4 C's

Of course, there is nothing wrong with preferring a certified or non-certified diamond. 

If she loves it, buy it!

The certification simply helps you understand the pricing differential. It is like a pedigree. When you purchase a dog, you will pay more for one with a record of the descent of the animal, showing it to be purebred. The same is true for a certified diamond. It is a sort of "guarantee."

1. Clarity

It would be nice if every diamond were as “flawless” (F) as your loved one, but that is simply not the case. “Flawless” is the highest “Clarity” category, meaning that there are virtually no blemishes therein. The next category is “Internally Flawless,” (IF) which means that gemologists have found some external blemishes. You might see the next categories identified by their acronyms: Very Very Slightly Included (VVS1 or VVS2), Very Slightly Included (VS1 or VS2), Slightly Included (SI1 or SI2) or Included (I1 or I2). They differ by number, size or depth of the flaws on the diamond.

2. Color

“What color is your diamond?” Each mineral has a different color. Your diamond is rated on GIA’s Color Scale from D (which is colorless) to Z (which is brown). Each letter corresponds to another gradation (i.e. E is almost colorless.) The most rare diamonds are the colorless ones (so you should expect to pay more for them). “How is the color determined?” It is similar to your paint or rug chart. Each diamond is compared to the GIA's master set. “Fluorescence” is when a diamond emits a visible light under ultraviolet radiation (but it does not have a formal rating system).

3. Cut

“What is the quality of the diamond “Cut?” This is similar to what you would find in baseball card or coin collections. The range includes Excellent, Very Good, Good, Fair and Poor. “Why is a diamond’s sparkle so amazing?” The concepts of “Brightness,” “Fire” and “Scintillation” are at work. Brightness (also called "Brilliance") is the total amount of white light reflected from the surface and interior. Fire is the “flare” of color emitted. Scintillation is the interplay of light and dark areas, along with the sparkle during movement. There are also different shapes, like Heart, Oval or Pear. A diamond’s proportions will affect its light performance. The best light performance is achieved by fine proportions, symmetry and a good polish. The gemologists measure the table size, crown angle, total depth and other geometrical features of the diamond.

4. Carat Weight

One carat equals 200 milligrams of weight, which is about the same weight as a paper clip. For diamonds under one carat, the carats are further subdivided into points. For example, one-half carat equals 50 points. So, you might see some of the lower carat diamonds only quoted in points.
