What Are Lab Grown Diamonds?
Synthetic diamonds, also referred to as lab-grown diamonds, are created in a laboratory with equipment that mimics the natural diamond-forming process.
They are frequently more reasonably priced and come from ethical sources, but they share the same chemical, physical, and visual qualities as real diamonds.
Chemical Vapor Deposition and High-Pressure High-Temperature are the two main processes used to generate diamonds in laboratories. They yield diamonds that are nearly exact replicas of real diamonds.

Why Buy Lab Grown Diamonds?
Price
Lab-grown diamonds are 30-40% cheaper than natural diamonds of similar quality. So you get more for your money. The savings can be huge, so you can get a bigger or higher quality diamond in your budget. (source: Statista)
Ethical
Lab-grown diamonds are free from the ethical issues of diamond mining, human rights abuses, and environmental damage.
Choosing lab-grown diamonds supports sustainable and responsible practices. These diamonds are produced without the social and ecological impact of traditional diamond mining, so they are an ethical choice for conscious consumers.
Quality and Choice
Lab grown diamonds are the same quality as natural diamonds, with a wide range of sizes, shapes and colours. They are graded to the same standards so high quality and consistency is guaranteed.
Technology has advanced so lab grown diamonds can be produced with fewer inclusions and more clarity, often better than natural diamonds.
How to Buy Lab-Grown Diamonds (Tips)
Know the 4Cs
Before you buy a lab grown diamond, get to know the 4Cs: cut, color, clarity and carat weight. These are the factors that determine the look and value of the diamond. Knowing these will help you make an informed decision and choose a diamond that matches your needs and budget.
Set a Budget
Decide how much you want to spend before you start shopping. Setting a budget will help you narrow down your options and stay within your means. Lab grown diamonds offer great value so you can find a beautiful diamond in your budget.
Choose a Trustworthy Retailer
Choose a retailer with a good reputation for selling lab-grown diamonds. Look for certifications from recognized gemological institutes like GIA or IGI. Check customer reviews and ratings to see if the retailer has a history of happy customers.
Compare Prices
Compare prices from different retailers to get the best deal. Online stores often have lower prices due to lower overheads. But consider the added value of in-store purchases where you can see the diamond in person and get personal service.
View the Diamond
Inspect the diamond in person or through high res images and videos provided by online retailers. Look for inclusions and blemishes and check the cut. High res images and videos will give you a close up view of the diamond’s features.
Check the Return Policy
Before you buy, check the retailer’s return policy. Make sure you can return the diamond if it’s not what you expected. A flexible return policy gives you peace of mind and lets you shop with confidence.
What’s the Warranty
Check if the retailer offers a warranty on the diamond. A good warranty covers defects and repairs, so you’re protected from your investment. It’s an added bonus that the retailer stands behind their product.
How are Lab Grown Diamonds Graded?
Lab-grown diamonds are graded using the same criteria as natural diamonds: the 4Cs – cut, color, clarity, and carat weight.
Here’s a quick guide:
Cut
The cut of a diamond is how well it’s been cut and faceted to maximize its brilliance. A well cut diamond will sparkle beautifully. Cut is graded from Excellent to Poor, Excellent being the highest.
Color
Diamond color is graded from D (colorless) going to Z (light yellow or brown). Colorless diamonds are the most valuable because they allow more light to pass through so more brilliance and fire. Lab grown diamonds can be produced in many colors so more options for you.
Clarity
Clarity measures external and internal imperfections, known as inclusions and blemishes. Diamonds with fewer inclusions are more valuable. Clarity is graded from Flawless (no inclusions visible under 10x magnification) to Included (inclusions visible to the naked eye).
Carat
Carat weight is the size of the diamond. Larger diamonds are rarer and more valuable. 1 carat is 200 milligrams. Lab-grown diamonds are available in many-carat weights, so you can find the one that suits you.
Conclusion
Finding the right place to buy lab-grown diamonds can significantly impact your purchasing experience.
This guide has highlighted some of the best retailers where to buy lab-grown diamonds so you can get high-quality, ethically sourced diamonds at a fair price.
When considering where to buy lab-grown diamonds, prioritize reputable retailers like Brilliant Earth, James Allen, Blue Nile, and Clean Origin.
