Diamonds are evaluated based on four key characteristics known as the 4 Cs: Carat (weight), Cut (shape and quality of the cut), Color, and Clarity.
The beauty of a lab-grown diamond depends more on its Cut than any other factor. While nature dictates color and clarity, the skill of the master cutter determines how a stone interacts with light. We carefully categorize our inventory into specific grades to help partners evaluate precision, ensuring that every diamond from classic rounds to fancy shapes exhibits maximum potential for fire and scintillation.
'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' 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.
Reflects a majority of the light that enters the diamond, for an above average appearance. An excellent value compared to higher cut grades.
Allows 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.
Clarity evaluates the unique birthmarks of a diamond. Lab-grown diamonds, like their earth-mined counterparts, can contain tiny 'inclusions' or surface 'blemishes.' Because our diamonds are grown in a highly controlled environment, we specialize in high-clarity stones that offer maximum transparency and brilliance.
In the world of diamonds, color refers to the degree of 'whiteness' or transparency within the stone. At Dsons Impex, we specialize in the growth of Type IIa diamonds—the most chemically pure category. By utilizing advanced CVD technology, we minimize trace elements like nitrogen that typically cause yellow or brownish hues. Our mastery over the growing environment allows us to consistently produce stones in the Colorless (D-F) and Near Colorless (G-J) range, providing our partners with exceptional brilliance and optical clarity.
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.
| Color Grades | D E F | G H I J | K L M | N to R | S to Z |
|---|---|---|---|---|---|
| Parameters | Colorless | Near Colorless | Faint | Very Light | Light |
Carat refers specifically to the weight of the diamond, with one carat equaling 200 milligrams. While often confused with size, a diamond’s visual 'spread' is actually a result of both its weight and the quality of its cut. At Dsons Impex, we maintain a diverse and consistent inventory ranging from precision-cut pointers (0.01ct+) to significant solitaires of 2.00ct and beyond. Our advanced HPHT & CVD growth process allows us to provide retailers with the exact weight specifications required for both bespoke high-jewelry and high-volume commercial collections.
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,
The true fire of a diamond is finalized through its Polish and Symmetry. Polish refers to the microscopic smoothness of each facet, ensuring a mirror-like surface that maximizes luster. Symmetry involves the exact alignment and intersection of those facets; even a slight deviation can disrupt the flow of light. At DSons Impex, we aim for the 'Triple Excellent' standard, ensuring that every stone achieves a harmonious balance of light return and aesthetic perfection.
Polish and symmetry are crucial factors in assessing the quality of a diamond cut. Polish relates to how smooth each facet of a diamond is, while symmetry involves the alignment of these facets.
Imagine polish as the smoothness of the diamond's surfaces, evaluated by gemmologists. When a diamond is being cut and polished, dislodged crystals dragged across its surface by the polishing wheel can cause distortions. These imperfections, if severe, may interfere with the way light enters and exits the diamond, affecting its overall appearance.
Fluorescence refers to the visible glow a diamond emits when exposed to ultraviolet (UV) rays. While common in earth-mined diamonds, large amounts of fluorescence can sometimes impact the stone's transparency, leading to a 'milky' appearance. At DSons Impex, our precision CVD growth process allows us to strictly control the presence of trace elements. We prioritize an inventory of diamonds with 'None' to 'Faint' fluorescence, ensuring that our stones maintain their crisp, clean brilliance even in direct sunlight.
A diamond’s brilliance is a result of its precise geometric proportions. By understanding the specific components—from the Table to the Culet—partners can better evaluate how a stone manages light through dispersion and scintillation. At Dsons Impex, we ensure every facet is engineered to exact mathematical ratios, maximizing the optical performance of our lab-grown diamonds.
