Lab grown diamonds have taken the jewellery world by storm, offering a stunning, ethical alternative to mined diamonds. As more people in the UK embrace this modern choice, finding the best lab grown diamonds can feel overwhelming, especially if you’re not sure what to look for.

In this guide, we’ll walk you through everything you need to know about choosing lab grown diamonds, including insider tips on finding the best quality, where to shop, and how to ensure you get the most value for your money.

Why Choose Lab Grown Diamonds?

Lab grown diamonds have risen in popularity for several reasons. They are real diamonds, identical in appearance and structure to natural diamonds, but without the environmental and ethical concerns associated with mining.

For UK buyers, they offer incredible value as they are typically 20-40% cheaper than their natural counterparts. On top of that, the ability to customise lab grown diamonds opens up endless possibilities, allowing you to design something unique that reflects your personal style.

Understanding Lab Grown Diamonds: What You Need to Know

Before you start shopping, it’s important to understand what lab grown diamonds actually are. Created in a laboratory, these diamonds share the same physical, chemical, and optical properties as natural diamonds. They are not imitation diamonds (like cubic zirconia), but rather real diamonds grown through scientific methods.

Lab grown diamonds are graded in the same way as natural diamonds using the 4Cs – cut, clarity, colour, and carat. This means that you can expect the same level of beauty and durability, with a more affordable price tag.

How Lab Grown Diamonds Are Made

Lab grown diamonds are created through two main processes: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD). Both methods replicate the natural conditions under which diamonds form in the earth, producing real diamonds over a much shorter timeframe.

HPHT uses intense pressure and heat to turn carbon into diamonds, while CVD involves breaking down carbon-rich gases to form diamonds layer by layer. The quality of diamonds produced by both methods is excellent, and once cut and polished, lab grown diamonds are indistinguishable from mined diamonds. To see a range of cuts, check out round diamonds or explore unique shapes like marquise diamonds.

What to Look for When Buying Lab Grown Diamonds

When it comes to choosing the best lab grown diamond, you’ll want to focus on the 4Cs: cut, clarity, colour, and carat weight. Here’s how to approach each factor:

  • Cut: The cut of the diamond affects how much light it reflects, which determines its brilliance. Opt for a well-cut diamond to ensure maximum sparkle. Popular shapes include oval diamonds and emerald cut diamonds.
  • Clarity: Clarity refers to the presence of internal flaws (inclusions) or surface blemishes. Choose a diamond with a clarity grade of VS2 or higher to ensure any imperfections are invisible to the naked eye.
  • Colour: Diamonds are graded on a scale from D (colourless) to Z (light yellow or brown). For the best value, choose a diamond in the near-colourless range (G-H), which appears almost identical to a colourless diamond at a lower price.
  • Carat Weight: Carat weight refers to the size of the diamond. While larger diamonds are more expensive, you can balance size and quality by opting for a slightly lower carat weight in exchange for a better cut or clarity.

Finally, make sure the diamond is certified by a reputable gemological institute like GIA or IGI, which guarantees its authenticity and quality.

Best Places to Buy Lab Grown Diamonds in the UK

The UK offers plenty of options when it comes to buying lab grown diamonds. You can choose from well-known jewellers with brick-and-mortar stores or explore online retailers. Both options have their advantages.

  • Established jewellers: Buying from a reputable jeweller allows you to see the diamonds in person and benefit from expert advice. Many jewellers also offer bespoke services, allowing you to customise your diamond jewellery.
  • Online retailers: If you’re looking for the best prices, online retailers often have more competitive deals. Sites like this one offer a wide selection of lab grown diamonds, and you can filter your search by cut, colour, clarity, and carat weight.

Whichever option you choose, be sure to compare prices and look for reviews to ensure you’re buying from a trustworthy seller.

Tips for Getting the Best Value

Getting the best value for your money doesn’t mean compromising on quality. Here are a few tips to ensure you find the best deals on lab grown diamonds:

  • Compare prices: Look at multiple retailers and don’t be afraid to ask for a price match. Often, online retailers have lower overhead costs and can offer better deals than physical stores.
  • Consider wholesale diamonds: Buying wholesale diamonds can save you a significant amount. Wholesale options give you access to high-quality diamonds at a lower price point, perfect for creating custom jewellery.
  • Look for promotions: Many jewellers run sales, especially around holidays. Sign up for newsletters to stay updated on upcoming promotions.

Ethical Considerations: Why Lab Grown Diamonds Matter

One of the main reasons people choose lab grown diamonds is their ethical appeal. Unlike natural diamonds, which are often linked to environmental degradation and questionable mining practices, lab grown diamonds are created in a controlled environment with minimal impact on the planet.

In the UK, where sustainability is becoming an increasingly important issue, lab grown diamonds are an eco-friendly choice. Not only do they avoid the ethical concerns associated with mined diamonds, but they also contribute to a more sustainable future in the jewellery industry. For a more distinctive option, consider fancy coloured diamonds, which offer beautiful hues without the ethical drawbacks of mining.

Customising Lab Grown Diamond Jewellery

One of the greatest advantages of lab grown diamonds is the ability to customise your jewellery. Whether you’re designing an engagement ring or a special necklace, lab grown diamonds offer the flexibility to create something unique.

Many jewellers, both online and in-store, allow you to choose your diamond and setting. You can select the shape, metal, and design to suit your taste. If you’re looking for something truly special, you might explore options like heart shaped diamonds to make your jewellery stand out.
