Lab grown diamonds are creating quite the buzz in the jewellery world, and for good reason. They offer all the sparkle and beauty of natural diamonds, but at a fraction of the cost and without the environmental or ethical concerns tied to mining.

However, shopping for a lab grown diamond requires a bit of know-how to ensure you’re getting the best quality for your money.

In this guide, we’ll walk you through everything you need to consider when shopping for lab grown diamonds, so you can make an informed, confident decision.

Understanding the 4Cs in Lab Grown Diamonds

When it comes to diamonds, whether natural or lab grown, the 4Cs – cut, colour, clarity, and carat – are essential to understanding a diamond’s quality.

Each plays a crucial role in how the diamond looks and how much it costs.

Cut

This refers to how well the diamond has been shaped and polished. A well-cut diamond will reflect light beautifully, creating that iconic sparkle. In lab grown diamonds, look for an ‘Excellent’ or ‘Very Good’ cut grade, which indicates that the diamond has been expertly crafted to maximise its brilliance.

Colour

Diamonds come in a range of colours, from completely colourless to those with faint yellow or brown tints. The closer a diamond is to being colourless, the more valuable it typically is. When shopping for lab grown diamonds, look for a colour grade of D (completely colourless) to G (nearly colourless) for the best quality. If fancy coloured diamonds appeal to you, take a look at the available selection of fancy coloured diamonds and lab grown fancy coloured diamonds.

Clarity

Clarity refers to how many internal or external imperfections, known as inclusions and blemishes, a diamond has. While lab grown diamonds are often more affordable, you’ll still want to choose one with minimal inclusions for a cleaner, clearer appearance. A clarity grade of VS1 or VS2 is a solid choice, as any imperfections will be invisible to the naked eye.

Carat

Carat weight is how we measure the size of a diamond. Larger diamonds are rarer and thus more expensive. The great thing about lab grown diamonds is that you can often afford a larger carat size without the price tag associated with natural diamonds. Whether you go for a modest or sizeable carat weight, make sure it balances well with the other 3Cs to maintain quality. For example, if you prefer pear shaped diamonds, explore the pear lab grown diamond collection.

Certification and Authenticity

Certification is vital when purchasing a lab grown diamond. Just like with natural diamonds, you’ll want to ensure your stone has been graded by a reputable certification body. In the UK, look for certificates from trusted institutions such as the Gemological Institute of America (GIA) or the International Gemological Institute (IGI). These certificates will detail the diamond’s 4Cs, as well as other important information about its quality and origin.

Make sure you double-check the details on the certificate before purchasing. It’s also worth asking your jeweller for verification of the diamond's lab grown status. While it’s rare, some unscrupulous retailers may try to pass off imitation stones as lab grown diamonds, so having that certification in hand gives you peace of mind.

Price Comparison: Lab Grown vs Natural Diamonds

One of the biggest draws of lab grown diamonds is the price difference compared to their natural counterparts. Because they’re created in a controlled environment rather than mined from the earth, lab grown diamonds tend to be around 30-40% cheaper than natural diamonds of the same size and quality.

This makes lab grown diamonds an excellent choice for anyone looking to maximise their budget, whether you’re after a larger carat size or a higher colour and clarity grade. Additionally, many people appreciate the eco-friendly and ethical advantages of lab grown diamonds, which can help you feel even better about your purchase.

Ethical and Environmental Considerations

Lab grown diamonds are often hailed as the more ethical and sustainable option, and it’s easy to see why. Unlike natural diamonds, which are extracted from the earth in a process that can have a significant environmental impact, lab grown diamonds are created in high-tech laboratories. This means there’s no mining, which reduces habitat destruction, water use, and carbon emissions.

Moreover, lab grown diamonds are free from the ethical issues that sometimes plague the natural diamond industry, such as conflict or "blood" diamonds. If environmental sustainability and ethical sourcing are high on your list of priorities, lab grown diamonds are a brilliant choice.

Customisation and Design Options

One of the joys of choosing lab grown diamonds is the wide range of customisation options available. Whether you’re designing a bespoke engagement ring or selecting a special piece of jewellery, lab grown diamonds provide a high level of flexibility. Many jewellers in the UK offer a variety of settings and styles for lab grown diamonds, allowing you to personalise your jewellery to match your taste.

Whether you love classic solitaire settings, vintage-inspired designs, or something more contemporary, there’s something for everyone. Lab grown diamonds are also available in a range of fancy cuts and shapes, from the popular round brilliant to the more unique pear or marquise cuts. For instance, if you’re drawn to more intricate shapes, you might find heart lab grown diamonds or oval lab grown diamonds appealing.

Longevity and Durability of Lab Grown Diamonds

One common question is whether lab grown diamonds are as durable as natural diamonds. The good news is that lab grown diamonds are every bit as hard and resilient as their natural counterparts. They’re made of the same material – pure carbon – and are graded at 10 on the Mohs scale of hardness, making them suitable for everyday wear in rings, earrings, and other jewellery.

As with any piece of fine jewellery, proper care is essential to keep your lab grown diamond looking its best. Regular cleaning and professional inspections will ensure your diamond maintains its sparkle and stays secure in its setting.

Where to Buy Lab Grown Diamonds in the UK

With the rise in popularity of lab grown diamonds, more retailers and jewellers across the UK are offering them. You can find lab grown diamonds both online and in physical stores, though each option has its pros and cons.

Online retailers often offer a wider selection of diamonds and more competitive prices. However, buying in-store gives you the opportunity to see the diamond in person before you commit, which can be helpful if you’re new to shopping for diamonds. When choosing a retailer, whether online or in-store, make sure they provide certification from a reputable grading institution and have a solid reputation for customer service. If you're searching for wholesale options, consider looking at the diamond dealer section.
