Cut is a diamond’s most important characteristic.
Unique Diamond Boutique recommends selecting the highest cut grade within your budget. The reason is simple: of the Four Cs (Cut, Clarity, Carat, and Color), no other characteristic has a greater influence on a diamond’s appearance. A diamond’s cut grade is an objective measure of a diamond’s light performance; or, what we generally think of as “sparkle.” When a diamond is cut with the proper proportions, light is returned out of the top of the diamond (which gemologists refer to as the table). If it is cut too shallow, light leaks out of the bottom; too deep and it escapes out of the side.
- Certified Diamond Brokers Signature Ideal cut: Our most brilliant cut, representing roughly the top 1% of diamond quality based on cut. The highest grades of polish and symmetry allow it to reflect even more light than the standard ideal cut.
- Ideal cut: Represents roughly the top 3% of diamond quality based on cut. Reflects nearly all light that enters the diamond. An exquisite and rare cut.
- Very good cut: Represents roughly the top 15% of diamond quality based on cut. Reflects nearly as much light as the ideal cut, but for a lower price.
- Good cut: Represents roughly the top 25% of diamond quality based on cut. Reflects most light that enters. Much less expensive than a very good cut.
- Fair cut: Represents roughly the top 35% of diamond quality based on cut. Still a quality diamond, but a fair cut will not be as brilliant as a good cut.
- Poor cut: Diamonds that are generally so deep and narrow or shallow and wide that they lose most of the light out the sides and bottom. Certified Diamond Brokers does not carry diamonds with cut grades of poor.
What Cut Grade Is Right For Me?
For the best possible cut, look to the Certified Diamond Brokers Signature Collection. Custom made exclusively for Certified Diamond Brokers, each Signature Collection diamond is hand-selected and cut to the most exacting standards, guaranteeing one of the finest cuts available in the world.
Diamonds with a cut grade of good or very good represent an excellent combination of beauty and value.
Now that you have a solid understanding of how cut affects a diamond’s light performance (or sparkle), learn about the second of the Four Cs, color below.
Color refers to a diamond’s lack of color, grading the whiteness of a diamond.
A color grade of D is the highest possible, while Z is the lowest.
Color manifests itself in a diamond as a pale yellow. This is why a diamond’s color grade is based on its lack of color. The less color a diamond has, the higher its color grade. After cut, color is generally considered the second most important characteristic when selecting a diamond. This is because the human eye tends to detect a diamond’s sparkle (light performance) first, and color second.
At Unique Diamond Boutique, you’ll find only the finest diamonds with color graded D-J. Diamonds graded J or better are colorless or near-colorless, with color that is typically undetectable to the unaided eye.
What Color is Right for Me?
- For the purist, look for a colorless diamond with a grade of D-F for a diamond with no discernible color.
- For an excellent value in a diamond with little or no noticeable color to the unaided eye, look for a near-colorless grade of G-I
Now that you understand how color affects the white look of a diamond, you are ready to learn about Clarity.
Clarity is a measure of the number and size of the tiny imperfections that occur in almost all diamonds.
Many of these imperfections are microscopic, and do not affect a diamond’s beauty in any discernible way.
Much is made of a diamond’s clarity, but of the Four Cs (Cut, Clarity, Carat, and Color), it is the easiest to understand; and, according to many experts, generally has the least impact on a diamond’s appearance. Clarity simply refers to the tiny, natural imperfections that occur in all but the finest diamonds. Gemologists refer to these imperfections by a variety of technical names, including blemishes and inclusions, among others. Diamonds with the least and smallest imperfections receive the highest clarity grades. Because these imperfections tend to be microscopic, they do not generally affect a diamond’s beauty in any discernible way.
What Clarity Grade Is Right For Me?
- Select an “eye-clean” diamond – one that has no imperfections visible to the unaided eye. An excellent value, diamonds of this clarity are much less expensive than flawless (FL) or internally flawless (IF) diamonds, which are extremely rare and command higher prices.
- Frequently, imperfections in diamonds graded slightly included (SI) are not visible to the unaided eye, making them an excellent value. If you’re considering a diamond with an SI clarity grade, call to speak to a diamond and jewelry consultant who will review the diamond to ensure the imperfections are not visible to the unaided eye.
Now that you understand clarity, learn about a diamond’s Carat Weight.
By far the most widely-selected and traditional diamond cut. Round diamonds are cut specifically for brilliance, hence the name, “round brilliant,” and radiate the most fire and color than any other cut.
The princess is considered a “fancy cut,” as are all diamond shapes other than round. It is square in shape and will be complimented by both contemporary and traditional setting designs. A stylized cut, it is best to determine specifically whether the princess shape is appealing to the wearer. Like a heart cut diamond, the princess is a shape the wearer will typically specify as her preferred cut, or not.
The emerald cut diamond is a very sophisticated and elegant shape. It is “step cut” rather than “brilliant cut,” therefore, it is intended to have a beautiful, clean look, without the fire of brilliant cuts. Because the step cut cannot hide flaws as easily as a brilliant cut, the clarity grade of the emerald cut diamond will need to be high.
A truly unique cut, like the emerald cut, the asscher is “step cut” as opposed to “brilliant cut.” However, because of the placement of the step cuts, the asscher will radiate more fire than an emerald cut. A great choice for a person who enjoys wearing something unusual that not everyone else has.
Like the oval cut, a great benefit of the marquis shape is that it will look larger than its actual carat weight. It is a romantic and feminine shape that is enhanced by both modern and antique-style settings.
Like the marquis cut, a great benefit of the oval is that it looks larger than its actual carate weight. It is cut for brilliance, like the round brilliant, and therefore will radiate a lot of fire. A versatile cut, the oval is great choice for either traditional or contemporary setting designs.
The radiant cut is unique because it is a modified round brilliant cut. Therefore, it will radiate fire and brilliance, yet the shape will be square or rectangular. This is the best of both worlds for the wearer who does not want to sacrifice brilliance but enjoys a linear shaped diamond.
Very elegant, this is a fancy brilliant cut and is one of the most sophisticated and stylized shapes. It is up to the wearer whether the point is worn facing up or down, but diamond lore suggests that if the point is facing down, her heart is taken!
A fancy brilliant cut, the heart is the perfect cuf for the very feminine and romantic. A stylized cut, it is best to determine specifically whether the heart shape is appealing to the wearer. Like the princess cut, the heart cut is a shape the wearer will typically specify as her preferred cut, or not.
This is a beautiful brilliant cut that has become very popular in recent years. Like the radiant cut, the cushion cut is unique because it is a modified round brilliant cut. Therefore, it radiates fire and brilliance, yet the shape is geometric. This is the best of both worlds for the wearer who does not want to sacrifice brilliance but enjoys a linear shaped diamond.
