Lab grown diamonds have become increasingly popular in recent years as an alternative to natural diamonds. They offer many advantages, including being more affordable, more sustainable, and having fewer ethical concerns. In this article, we will explore what makes the best lab grown diamonds and what factors to consider when choosing one.
The 4C’s of Lab Grown Diamonds
Just like natural diamonds, lab grown diamonds are evaluated based on the 4C’s: cut, color, clarity, and carat weight.
Cut: A well-cut lab grown diamond will have excellent sparkle and brilliance. The cut determines how light enters and exits the diamond, so it is crucial for maximizing its beauty. Look for diamonds with precise facet angles and a symmetrical shape.
Color: The color of a lab grown diamond can range from colorless to slightly tinted. Colorless diamonds are the most valuable, but some people prefer diamonds with a hint of color for a unique look. The Gemological Institute of America (GIA) grades diamond color on a scale from D (colorless) to Z (light yellow or brown).
Clarity: Clarity refers to the presence of internal or external flaws in the diamond. Lab grown diamonds can have a high level of clarity, as they are grown in a controlled environment. However, some may still have minor inclusions that can affect their appearance. Look for diamonds with a clarity grade of VS (very slightly included) or better for the best quality.
Carat Weight: Carat weight measures the size of the diamond. Larger diamonds are generally more expensive, but the price also depends on the other 3C’s. When choosing a lab grown diamond, consider your budget and personal preference for size.
Types of Lab Grown Diamonds
There are two main methods of growing diamonds in a laboratory: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).
HPHT Diamonds: These diamonds are grown by subjecting carbon to high pressure and temperature, mimicking the natural conditions under which diamonds form in the earth. HPHT diamonds can have excellent color and clarity, and they are often more affordable than CVD diamonds.
CVD Diamonds: CVD diamonds are grown by depositing carbon atoms onto a substrate in a low-pressure chamber. This method allows for more precise control over the growth process, resulting in diamonds with fewer impurities and better color. CVD diamonds are also known for their excellent clarity and can be produced in larger sizes.
Top Brands of Lab Grown Diamonds
Several brands are known for producing high-quality lab grown diamonds. Here are some of the top ones:
Vrai: Vrai is committed to sustainability and exclusively works with lab grown diamonds. Their diamonds are created in a zero-emissions diamond foundry and are hand-chiseled and polished by artisans, resulting in some of the best cuts on the market. Vrai offers a range of styles, from minimalist solitaires to elegant pavé settings.

Ethical and Environmental Considerations
One of the main reasons people choose lab grown diamonds is their ethical and environmental benefits.
No Mining Impact: Lab grown diamonds do not require mining, which reduces the environmental damage associated with traditional diamond mining. Mining can cause soil erosion, water pollution, and habitat destruction, so choosing lab grown diamonds is a more sustainable option.
Ethical Sourcing: Lab grown diamonds are not associated with the ethical issues that can be present in the natural diamond industry, such as conflict diamonds or child labor. By choosing lab grown diamonds, consumers can ensure that their purchase is free from these concerns.
Cost and Value
Lab grown diamonds are generally more affordable than natural diamonds, making them a great option for those on a budget. The cost of lab grown diamonds can vary depending on the 4C’s, as well as the brand and retailer. However, you can typically expect to pay 20% to 30% less for a lab grown diamond compared to a natural diamond of the same quality.
Conclusion
When it comes to choosing the best lab grown diamonds, there are several factors to consider, including the 4C’s, the type of diamond, the brand, and the ethical and environmental benefits. By doing your research and considering your personal preferences and budget, you can find a lab grown diamond that is both beautiful and affordable. Whether you are looking for an engagement ring, a special gift, or a piece of jewelry for yourself, lab grown diamonds offer a great alternative to natural diamonds.
