The 4 C's of a Diamond
Mastering the Art of Lab-Grown Diamond Cutting
When it comes to grading lab-grown diamonds, cut quality takes center stage. Expert lab-grown diamond manufacturers understand that the sparkle and brilliance of a diamond hinge on the precision of its cut. Fancy cut lab-grown diamonds are meticulously categorized into various grades, helping customers assess and appreciate the cut quality. These grades play a pivotal role in determining the unique cut of each diamond."
Excellent'Excellent' cut diamonds reflects the maximum amount of brilliance and fire. It reflects nearly all light that enters the diamond, creating exceptional sparkle and life.
Very Good'Very Good' cut diamond properly reflects most of the light that enters the diamond, producing superior fire and brilliance. Under normal lighting conditions, an excellent cut is reflected in Lab Grown Diamonds at wholesale price.
GoodReflects a majority of the light that enters the diamond, for an above average appearance. An excellent value compared to higher cut grades.
Fair/PoorAllows much of the light entering the diamond to escape from the sides or bottom, reducing perceived fire and brilliance. More acceptable in diamonds weighing less than 0.75 carats, where differences in sparkle are more difficult to perceive. The diamond may appear noticeably dull and lifeless, even to an untrained eye.
Lab-Grown Diamond Clarity
Diamond clarity is all about the number and placement of 'inclusions' or flaws that can interfere with the passage of light through the diamond. These clarity ratings are grouped into categories to help you understand a diamond's quality.
Flawless (without inclusions or imperfections)
Very, Very Slightly Included (VVS1 and VVS2)
Very Slightly Included (VS1 and VS2)
Slightly Included (SI1 and SI2)
Included (I1, I2, and I3) (with inclusions or imperfect)
Lab-Grown Diamond Color
When experts talk about diamond color, they're mainly talking about the presence or absence of color in the diamond. CVD Diamond manufacturers create diamonds that are 100% pure carbon and, as a result, they are completely colorless. However, most diamonds have some level of color due to tiny traces of elements like nitrogen, boron, hydrogen, or others. In most cases, these traces of nitrogen cause a faint yellow or brownish hue in the diamond.
Method Of Diamond Color Grading:
To accurately grade a diamond's color, it should be examined in isolation because the metal it's set in can influence how we perceive its color. For instance, a slightly yellow diamond may appear more brilliant when set in yellow gold, while it might seem less yellow in white gold or platinum settings.
To grade a diamond's color, it is placed table-down, pavilion up, and then magnified under a 10X loupe. The process involves using a lettering system from D to Z to assess the amount of color in each diamond. The coveted 'D' grade is reserved for exceptionally rare completely colorless diamonds.
Diamond color grades are categorized into the following groups: Colorless diamonds and diamonds that exhibit yellow or yellowish-brown tones. These categories do not apply to fancy colored diamonds, which have their own distinct grading system.

Lab-Grown Diamond Carat Weight
When it comes to lab-grown diamonds and other gemstones, carat is the simplest 'C' to understand. Carat is a unit of weight, and it's directly linked to the size of the gem, even though people sometimes use these terms interchangeably. This term originates from measuring small weights using an ancient 'Carob' seed. Here's a table of common weight-related terms:
One Carat equals 0.200 grams (5 carats in 1 gram and 142 carats in 1 ounce).
A carat is divided into 100 parts each called a point. So,
- 1 Carat = 100 points
- Three Quarter Carat = 75 points
- Half Carat = 50 points
- Quarter Carat = 25 points
