Learn About Diamonds
Lab-grown diamonds, also known as synthetic diamonds or man-made diamonds, are diamonds that are created in a laboratory environment rather than being formed naturally beneath the Earth's surface. They have gained popularity in recent years due to their ethical and environmental advantages, as well as their high quality. Here's a detailed overview of labgrown diamonds and what you need to know before buying them
Diamond fluorescence is graded on a scale that ranges from "None" to "Very Strong" by reputable gemological laboratories such as the Gemological Institute of America (GIA).
Formation and Production
Lab-grown diamonds are created using two primary methods:
High-Pressure High-Temperature (HPHT):
This method simulates the high-pressure and high-temperature conditions deep within the Earth's mantle where natural diamonds are formed. Carbon is subjected to extreme pressure and temperature to crystallize into diamond.
Chemical Vapor Deposition (CVD):
In this method, a diamond seed is placed in a chamber filled with carbon-rich gases. The carbon atoms gradually accumulate on the seed, forming a diamond crystal layer by layer
The 4Cs of Diamond
Cut:
The cut of a lab-grown diamond refers to how well it has been shaped, faceted, and polished. The quality of the cut has a significant impact on a diamond's overall appearance, brilliance, and sparkle. A well-cut lab-grown diamond will have precise angles and facets that maximize its light performance.
Carat:
Carat weight measures the size of a lab-grown diamond. One carat is equivalent to 200 milligrams. Our diamonds are available in various carat weights, and the choice depends on personal preferences and the design of the jewelry.
Color:
Our Lab-grown diamonds are graded on a color scale that ranges from D (colorless) to Z (light yellow or brown). The less color a lab-grown diamond exhibits, the higher its color grade and value. Colorless or near-colorless lab-grown diamonds are highly sought after.
Clarity:
Clarity assesses the presence of internal or external flaws, known as inclusions and blemishes, respectively, in lab-grown diamonds. The clarity scale ranges from Flawless (no imperfections visible under 10x magnification) to Included (imperfections visible to the naked eye). Lab-grown diamonds with fewer imperfections are considered more valuable.
Shapes of Diamond
Round Brilliant:
The round brilliant cut is the most popular and classic diamond shape. It is known for its exceptional sparkle and fire, with 57 or 58 facets that maximize light reflection.
Princess:
Princess-cut lab-grown diamonds are square or rectangular with pointed corners. They offer a modern and elegant look, often with sharp, clean lines.
Emerald:
Emerald-cut diamonds have a rectangular shape with cut corners. They are characterized by a large, open table and step-cut facets that create a hall-of-mirrors effect.
Oval:
Oval-cut lab-grown diamonds combine the brilliance of round diamonds with an elongated, elegant shape. They can appear larger than round diamonds of the same carat weight.
Marquise:
Marquise-cut lab-grown diamonds have an elongated, boat-shaped outline with pointed ends. They create a dramatic and eye-catching look.
Pear:
Pear-shaped lab-grown diamonds, also known as teardrop diamonds, have one rounded end and one pointed end. They offer a unique and versatile appearance.
Radiant:
Radiant-cut diamonds have a square or rectangular shape with trimmed corners. They are known for their brilliance and can appear larger than other shapes of the same carat weight.
Cushion:
Cushion-cut lab-grown diamonds have a square or rectangular shape with rounded corners. They provide a vintage and romantic look with their soft, pillow-like appearance.
Ascher:
Ascher-cut diamonds are similar to emerald-cut diamonds but are square with step-cut facets. They have a classic and Art Deco-inspired appearance.
Heart:
Heart-shaped lab-grown diamonds are romantic and symbolic. They have a distinct heart outline and are popular for engagement rings and special occasions.
Cut Grade of Diamonds
The cut grade assesses the quality of a diamond's cut and how well it interacts with light. It is typically graded on a scale from Excellent to Poor.
Facets:
Diamonds have multiple flat surfaces called facets. The arrangement and angles of these facets determine how light enters, reflects, and exits the diamond.
Angles and Proportions:
The angles and proportions of the diamond's facets play a critical role in how it handles light. Well-cut diamonds have precise angles and proportions that maximize brilliance and sparkle.
Light Performance:
A well-cut diamond exhibits optimal light performance, with light entering through the table (top facet), reflecting internally, and returning to the viewer's eye with maximum brightness and fire.
Brilliance:
Brilliance refers to the brightness of the white light that a diamond emits.
Fire:
Fire refers to the colorful flashes of light (rainbow-like effect) that a well-cut diamond displays.
Scintillation:
Scintillation refers to the sparkle or pattern of light and dark areas that result from the diamond's movement or changes in lighting.
Here's an explanation of the different clarity grades for lab-grown diamonds:
Flawless (FL) and Internally Flawless (IF)
Lab-grown diamonds in these categories have no internal or external imperfections visible under 10x magnification. Flawless diamonds are exceptionally rare and highly prized.
Very, Very Slightly Included (VVS1 and VVS2)
These diamonds have very tiny inclusions that are difficult for a skilled grader to detect even under 10x magnification. VVS diamonds are of excellent quality and have minor imperfections.
Very Slightly Included (VS1 and VS2)
In this range, lab-grown diamonds have small inclusions that are somewhat easier to see under 10x magnification but are still considered very good in terms of clarity. They may have minor imperfections but are generally eyeclean, meaning that the inclusions are not visible to the naked eye.
Slightly Included (SI1 and SI2)
Lab-grown diamonds in this category have noticeable inclusions when examined under 10x magnification. SI1 diamonds may have inclusions that are difficult to see without magnification, while SI2 diamonds may have more noticeable inclusions. Some SI2 diamonds may have inclusions visible to the naked eye, depending on their size and location.
Included (I1, I2, and I3)
Diamonds in this category have inclusions that are easily visible under 10x magnification, and some may have inclusions visible to the naked eye. These diamonds tend to be less expensive due to their lower clarity grades and reduced visual appeal.
It's important to note that the clarity grade of a lab-grown diamond can significantly affect its price. Diamonds with higher clarity grades (e.g., Flawless, VVS) are typically more valuable because they have fewer imperfections, which can enhance their brilliance and sparkle.
Ideal Cut Diamond
Proportions:
An ideal cut diamond is cut with precise proportions that maximize its brilliance and fire. It typically has a table percentage of around 53-58% and a depth percentage of around 59- 62%.
Light Performance:
Ideal cut diamonds are known for their exceptional light performance. They exhibit excellent brilliance, fire, and scintillation.
Appearance:
These diamonds are highly sought after due to their stunning visual appeal. They appear bright and lively, with a balanced play of white light (brilliance) and colorful flashes (fire).
Deep Cut Diamond
Proportions:
A deep cut diamond has proportions where the depth percentage is higher than the ideal range (typically over 62%). This means the diamond is cut deeper than ideal.
Light Performance:
Deep cut diamonds may not perform as well in terms of brilliance and fire because they allow light to escape through the pavilion instead of being reflected back to the viewer's eye.
Appearance:
Deep cut diamonds may appear darker or less lively due to the inefficient use of light.
Very Shallow Cut Diamond
Proportions:
A very shallow cut diamond has proportions where the depth percentage is lower than the ideal range (typically below 59%). This means the diamond is cut shallower than ideal.
Light Performance:
Very shallow cut diamonds may also underperform in terms of brilliance and fire. Light can leak out of the bottom of the diamond, reducing its sparkle.
Appearance:
These diamonds may appear glassy or lackluster due to the poor light performance.
Diamond Proportions
Table Percentage:
The table percentage is the ratio of the width of the table facet to the overall width of the diamond. It affects the diamond's appearance and light performance.
Depth Percentage:
The depth percentage is the ratio of the diamond's depth (from the table to the culet) to its width. It influences how well the diamond reflects and refracts light
Crown Height:
The crown is the top portion of the diamond above the girdle. Its height relative to the pavilion (bottom portion) influences the diamond's brilliance.
Pavilion Depth:
The pavilion is the lower portion of the diamond below the girdle. Its depth affects how light exits the diamond.
Girdle Thickness:
The girdle is the widest part of the diamond, and its thickness can vary. A well-proportioned girdle ensures the diamond is stable and secure in a setting.
Culet Size:
The culet is the small facet at the bottom of the diamond. Its size can affect light reflection and symmetry.
What is Diamond Fluorescence ?
Diamond fluorescence refers to the phenomenon where a diamond emits a visible glow when exposed to ultraviolet (UV) light. It is a natural characteristic of some diamonds and is evaluated as part of a diamond's overall quality assessment.
Here are key points to understand about diamond fluorescence:
Causes of Fluorescence
Diamond fluorescence occurs due to the presence of trace elements, typically nitrogen, within the diamond's crystal structure.
When UV light, which is not visible to the human eye, interacts with these trace elements, it causes them to emit visible light, often in a bluish or whitish hue.
The strength of fluorescence can vary, with some diamonds exhibiting strong fluorescence, while others may show only faint or negligible fluorescence.
Grading Fluorescence
Diamond fluorescence is graded on a scale that ranges from "None" to "Very Strong" by reputable gemological laboratories such as the Gemological Institute of America (GIA).
The possible fluorescence grades are "None," "Faint," "Medium," "Strong," and "Very Strong."
Impact on Diamond Appearance
In most lighting conditions, especially daylight or incandescent light, fluorescence is not visibly apparent, and it does not affect a diamond's appearance.
Some individuals may even prefer diamonds with fluorescence because it can make the diamond appear slightly whiter, counteracting any faint yellowish tints.
However, in rare cases where a diamond exhibits very strong fluorescence and is exposed to strong UV light (such as sunlight with a significant UV component), it can appear hazy or milky, affecting transparency.
Are Lab Grown Diamond just as real as Natural Diamond ?
Answer is “Yes! Lab-grown diamonds are indeed real diamonds; they share the same chemical, physical, and optical properties as natural diamonds. They are composed of carbon atoms arranged in a crystal lattice structure, just like diamonds formed in the Earth's mantle. Due to their identical chemical composition, lab-grown diamonds are often referred to as "synthetic" or "man-made" diamonds.
