What is a Lab Grown Diamond?
Before we dive into clarity, let’s define lab grown diamonds. These are real diamonds created in a controlled laboratory environment using cutting-edge technology. They have the same physical, chemical, and optical properties as mined diamonds but are grown above ground, making them more sustainable and ethical.
There are two main methods used to produce lab grown diamonds:
-
CVD (Chemical Vapor Deposition)
-
HPHT (High Pressure High Temperature)
Both methods yield high-quality diamonds that are virtually indistinguishable from their mined counterparts—even under a microscope.
Why Clarity Matters in Lab Grown Diamonds
Clarity refers to the presence (or absence) of internal and external imperfections, known as inclusions and blemishes. These imperfections can affect the way light passes through the diamond, influencing its brilliance and sparkle.
Even though lab grown diamonds are made in controlled environments, they can still develop inclusions during their growth process. That’s why it’s essential to refer to a lab diamond clarity chart when choosing the perfect stone.
What is the Lab Diamond Clarity Chart?
The lab diamond clarity chart is a standardized grading system used to assess the number, size, location, and visibility of inclusions within a diamond. This chart helps consumers, gemologists, and jewelers determine a diamond’s clarity grade.
Here are the main clarity grades found on the lab diamond clarity chart:
| Clarity Grade | Description |
|---|---|
| FL (Flawless) | No inclusions or blemishes under 10x magnification. Extremely rare and expensive. |
| IF (Internally Flawless) | No internal flaws, but may have slight surface blemishes. Very high quality. |
| VVS1 – VVS2 (Very, Very Slightly Included) | Inclusions are so tiny they are difficult to see even under 10x magnification. Excellent clarity. |
| VS1 – VS2 (Very Slightly Included) | Minor inclusions that are difficult to detect with the naked eye. Great value for high visual appeal. |
| SI1 – SI2 (Slightly Included) | Inclusions are visible under 10x magnification and may be visible to the naked eye. |
| I1 – I3 (Included) | Obvious inclusions that affect transparency and brilliance. Budget-friendly but less visually appealing. |
How to Use the Lab Diamond Clarity Chart When Shopping
When shopping for lab grown diamonds, it’s helpful to use the lab diamond clarity chart as a reference point to balance quality and budget. Here are a few tips:
-
Go for VS or SI grades for the best value. These grades often have inclusions that are not visible without magnification.
-
Avoid I1-I3 grades if brilliance and sparkle are important to you.
-
Remember that higher clarity often comes with a higher price tag. If you’re prioritizing size or cut, you might compromise a little on clarity without sacrificing beauty.
Comparing Lab Grown Diamonds to Natural Diamonds in Clarity
One of the benefits of lab grown diamonds is the higher quality control during production. As a result, many lab diamonds are available in higher clarity grades than mined ones at more affordable prices. You’re more likely to find a Flawless or Internally Flawless lab diamond without breaking the bank.
Using the lab diamond clarity chart, consumers can easily compare clarity grades between lab and natural diamonds, making it easier to spot great deals.
Do Inclusions Matter in Everyday Wear?
For most people, minor inclusions won’t affect the beauty of their diamond in day-to-day wear. A VS2 lab grown diamond may look just as stunning as a VVS1 to the untrained eye. The key is to work with a trusted jeweler and always ask to see magnified images or videos of the diamond.
The lab diamond clarity chart can guide your choice, but personal preference plays a big role too. Some buyers are perfectionists who only want the top grades, while others are happy with minor flaws they can’t even see.
The Role of Certification in Diamond Clarity
All reputable lab grown diamonds should come with a grading report from an independent gemological lab, such as IGI (International Gemological Institute) or GIA (Gemological Institute of America). This certificate includes a detailed analysis of the diamond, including where it falls on the lab diamond clarity chart.
Always check the certification before making a purchase to ensure you’re getting what you’re paying for.
Lab Diamond Clarity vs. Other 4Cs
Clarity is just one of the 4Cs that determine a diamond’s value. The others are Cut, Color, and Carat Weight. While the lab diamond clarity chart helps you judge clarity, don’t forget that cut has the biggest impact on how brilliant a diamond looks.
If you’re choosing between a higher clarity and a better cut, go with the cut. A well-cut SI1 lab grown diamond can sparkle more than a poorly cut VVS1.
Final Thoughts: Finding Your Perfect Lab Diamond
In today’s market, lab grown diamonds offer a more ethical, sustainable, and affordable way to enjoy the beauty of diamonds. By using the lab diamond clarity chart, you can confidently choose a stone that meets your needs and budget.
Clarity is important, but it’s just one piece of the puzzle. Balance it with cut, carat, and color to find the diamond that’s perfect for you.
FAQs About Lab Diamond Clarity
Q1: Are lab diamonds always flawless?
No. While they are made in controlled environments, lab grown diamonds can still have inclusions, which is why the lab diamond clarity chart is used to grade them.
Q2: What clarity grade offers the best value?
VS1 or VS2 typically offer the best balance between price and visual quality.
Q3: Can I see inclusions without a magnifying glass?
In lower clarity grades like SI2 or I1, yes. But VS and VVS inclusions are usually invisible to the naked eye.
Q4: Do clarity grades affect sparkle?
Yes, especially in lower grades. Inclusions can block light from passing through the diamond, reducing brilliance.
Q5: Should I always buy the highest clarity grade?
Not necessarily. Use the lab diamond clarity chart to find the best clarity within your budget, and consider the other 3Cs as well.
