Understanding the Characteristics of Your Diamond

Cut A Diamond's Cut Will Determine Its Sparkle

The higher a diamond’s cut grade, the greater the stone’s brilliance. You’ll be able to see the difference in sparkle and fire when you compare an Atia 81 or Excellent cut to a lower cut grade.

ColorA Diamond's Color Refers to Lack of Color

Color measures the “whiteness” of a diamond. For an exceptionally white diamond, choose a color grade of D, E or F, and we suggest a white metal setting to maximize its brilliance. If you are looking for the best value, consider a diamond with a near-colorless grade G, H, I or J.

Clarity Every Diamond is Different

All diamonds have natural characteristics or tiny imperfections. The actual clarity grade of a diamond is only as important as you want it to be.  We recommended that you choose a diamond based on what you see, and buy with your eyes, not with your ears.


(Internally Flawless) IF diamonds are the rarest diamonds that can be found and have no characteristics visible under 10x magnification. There are very few diamonds like this and are therefore the most expensive.


(Very Very Slightly Included) VVS1 diamonds are among some of the rarest diamonds on earth and have very few characteristics that are extremely difficult to detect under 10x magnification. Only an expert gemologist would be able to grade a diamond of such rarity making them among the most expensive diamonds you will find.


(Very Very Slightly Included) VVS2 diamonds are very rare and have characteristics that are extremely difficult to find under 10x magnification by trained gemologists. Their rarity makes them very expensive.


(Very Slightly Included) VS1 diamonds have characteristics that are very difficult to detect under 10x magnification and are impossible to see with the naked eye. Even a trained gemologist may have to take a second look to find characteristics under a microscope. They are quite rare and hard to find in the market, making them more expensive.


(Very Slightly Included) VS2 diamonds have characteristics that are difficult to find under 10x magnification and are almost impossible to see with the naked eye. They are rarer than diamonds with a lower clarity grade and are therefore more expensive.


(Slightly Included) SI1 diamonds may have a small amount of visible characteristics under 10x magnification but they are hard for an untrained eye to spot them. Usually these characteristics are not visible to the naked eye.


(Slightly Included) Si2 diamonds may have characteristics that are visible under 10x magnification and its possible you may see them with the naked eye. However, they are becoming more difficult to detect than an I1 diamond. Choosing an SI2 diamond can also be a great value if you are interested in a larger diamond within your budget.


(Included) I1 diamonds have characteristics that can be seen under 10x magnification and may be visible to the naked eye as well. However, they may be in a place where they are less noticeable due to the sparkle of the diamond or even the setting you choose to mount it in. Many clients choose I1 diamonds if the carat weight or color is more important to them.


(Included) I2 diamonds have characteristics that can be seen under 10x magnification and may be visible to the naked eye as well. Although you may be able to see these characteristics when looking at it loose, its possible some may be covered up in a setting, allowing you to focus on the true beauty and sparkle of the diamond. Remember, internal characteristics do not have an effect on how well the diamond sparkles.

Carat A Diamond's Weight Is Measured In Carats

Carat weight is the total weight of a diamond regardless of how it’s distributed. From the top, a poorly cut diamond may appear smaller than a diamond of equal weight. Diamond value is determined by all the 4Cs, not by carat weight alone.

Diamond Shape

A Beautiful Reflection of Your Unique Style

Choosing a diamond shape is really about personal preference. Whether your taste leans toward traditional, modern, classic or sophisticated, we’ll help you find the perfect shape and we’ll make sure it sparkles with you in mind.


The round brilliant cut diamond is by far the most popular shape. Over the past 100 years, diamond cutters have figured out exactly how to cut a round brilliant cut diamond to optimize the most sparkle possible. For the most sparkle, check out our exclusive Atia 81.

Diamond Settings

There are many ways to set a diamond. Some settings can make a diamond appear larger while others suggest a vintage-inspired style. Choosing a setting is a personal choice, and the options run from traditional to sophisticated and more.


The prong setting is the most popular and classic way of setting diamonds. It allows the most amount of light to travel through the diamond and is most commonly set with four or six prongs which is the most secure way to set a diamond. In a prong setting, your center diamond traditionally sits above the rest of the ring.

Conflict Free


What are "Conflict Diamonds"?
In the late 1990s, the diamond business became aware of the sale and exportation of some diamonds that were being used to fund rebel activities in parts of Africa. These diamonds became known as "conflict diamonds" or "blood diamonds." Although this was a small percentage of African diamonds, it was a situation that we could not ignore.

How do we know where the diamond is coming from?
A system is in place that requires all diamonds to include a statement confirming that the supplier adheres to the strict guidelines of the Kimberley Process. It has proven to be an effective way to keep “conflict diamonds” out of the world market. Those who do not comply are served significant sanctions that jeopardize their access to the legitimate world diamond market.

The Kimberley Process
In 2000, an initiative called the Kimberley Process was launched. The Kimberly Process is a set of laws with which all US diamond retailers must comply. It's a way to ensure that diamonds would never be used to illegally and brutally fund rebel action.

You can feel great about buying at Wedding Day.
Wedding Day Diamonds has a zero-tolerance policy against “conflict diamonds.” We run our business with the utmost integrity and follow the highest standard of ethics in order to ensure that the Kimberley Process is always upheld.

How We Buy Our Diamonds

From the mine to our stores, we purchase each and every diamond in the industry's most efficient way possible.By cutting out the middle men, we can pass our savings down to you.

Step 1: Sourcing

First and foremost, the only diamonds we will ever purchase are from diamonds that are excavated from conflict-free mines. After excavation, all mines send their raw jewels to site holders.

Step 2: Precision Cutting

We have built close relationships with our sight holders and work directly with them as they expertly cut our diamonds precisely to our specifications.

Step 3: Direct to Our Stores

Your diamond will come directly to our stores to be perfectly placed in your one-of-a-kind setting. With no middle men, the savings get passed on to you.

Diamond Certificates

Even though the diamond might be of high quality on paper, its brilliance could be far less than a diamond with lower qualities. So keep in mind that diamond certificates are simply a guide to determine the VALUE of the diamond, not the BEAUTY. And some are more reliable than others. These certificates can be important in understanding the true rarity of the diamond, but always remember to buy with your eyes! It’s your opinion that matters most.

GIA is the world's most respected gemological laboratory, entrusted with grading and identifying more gems than any other lab. If your diamond has a GIA certificate, you can be certain that what you paid for is what you got. At Wedding Day, most of our diamonds come with a GIA certificate and we always use GIA standard grading when determining the rarity of our diamonds.

In 1996, the American Gem Society opened a diamond grading lab to ensure consistent, consumer-oriented diamond grading reports. Wedding Day Diamonds is a member of the AGS and we fully support and recognize AGS practices. They are very comparable to GIA standards.

The International Gemological Institute (IGI) Diamond Report is a certification stating the authenticity of a diamond and it provides a reliable and accurate report based on an internationally recognized system. IGI creates certifications that are detailed and easy to understand so anyone can appreciate the unique qualities of their diamond.

The European Gemological Laboratories (EGL) are by far the least favored certification lab in the industry. Although they claim to be most reliable, we've compared their work to a GIA certification and there is an undeniable difference in the quality of the reports.

WARNING: If you fall in love with a diamond that comes with an EGL certification, just remember that the true grading is most likely 2-6 grades lower than it actually is. We want you to have 100% confidence in your diamond quality and we do that by selling you a diamond based on GIA standard grading: nothing less.

Putting it all together — beautifully.

Now that you understand what's behind every diamond, you can find the exact style you're looking for and stay within your budget.
