Loose diamonds are individual, unset stones available for bespoke jewellery and engagement rings. We offer a wide selection of loose diamonds that London clients trust for both quality and value. They offer flexibility to choose your diamond’s cut, clarity, carat, and colour before deciding on a setting, or purchasing as quality investment diamonds.

Yes, all of our diamonds are certified. Whether natural diamonds or lab-grown diamonds, each comes with an official grading report from internationally recognised gemmological institutes such as the GIA (Gemmological Institute of America) or the IGI (International Gemmological Institute). These certifications provide an independent assessment of the diamond’s 4Cs carat weight, cut, colour, and clarity, along with other important details that verify the stone’s authenticity and quality. Having a certified diamond means you can buy with complete confidence, knowing that the attributes of your stone have been professionally evaluated and documented.

At Regal, we are committed to sourcing only ethically and responsibly mined diamonds, and eco-friendly lab created diamonds. All our diamonds are conflict-free and comply with the Kimberley process. Our lab-grown diamonds offer the same beauty and sparkle as mined diamonds, but with a significantly smaller environmental footprint, providing you with a choice that aligns with your values.

Natural diamonds are formed over billions of years under intense heat and pressure deep within the Earth, while lab-grown diamonds are created in controlled environments using advanced technology that replicates the natural process. Both types of diamonds are chemically and physically identical, exhibiting the same brilliance and durability.

Natural diamonds often carry a greater historical and sentimental value due to their rarity. However, lab diamonds offer a more cost-effective option typically costing 30–40% less for the same grade without compromising on quality or appearance.

Often, yes. Hatton Garden jewellers work with direct access to certified stone suppliers and in-house workshops, which means savings on loose diamonds and bespoke pieces compared to high-street retailers and diamond dealers in London. Hatton Garden remains one of the most cost-effective locations in London for certified diamonds and bespoke engagement rings. At Regal, you’ll benefit from competitive pricing, ethical sourcing, and expert service under one roof, backed by community reputation and customer trust.

When selecting the perfect diamond, it’s important to focus on the 4Cs of diamond  - cut, which determines sparkle; colour grade, which influences brilliance; clarity, which reflects the purity of the stone; and carat weight, which affects its size and presence. Striking the right balance between these qualities ensures that your diamond engagement ring is as unique as your love story.

As trusted diamond specialists in Hatton Garden, we guide you through every step, helping you understand how each factor works together to create a ring that matches your style and budget. Whether you’re considering a natural diamond for timeless appeal or a lab-grown diamond for an ethical and modern choice, we provide expert advice tailored to your preferences.

With the widest selection of engagement rings in London, we make the process simple and enjoyable. The result is not just a beautiful ring, but a piece your partner will cherish for a lifetime.

Definitely, lab-grown diamonds are chemically, physically, and visually the same as natural diamonds and are graded by the same standards. Many couples choose them for their stunning brilliance, accessible price point, and consistent availability in popular carat sizes. Explore our collection of lab diamond engagement rings, offered in a variety of timeless and modern styles.

Choosing a lab-grown diamond for your engagement ring offers several advantages, including ethical sourcing and environmental sustainability. Additionally, they typically cost 20-40% less than natural diamonds, allowing you to invest in a larger or higher-quality stone without exceeding your budget. With the same brilliance and beauty as natural diamonds, lab-grown diamonds provide a responsible and stylish choice for your special moment.

Learn why choose lab diamonds for your engagement ring!

The best way to maximise value is to understand where you can be flexible without sacrificing beauty. For instance, a stone with a lower clarity grade, such as VS2 or SI1, can look just as eye-clean as a higher grade but at a more accessible price. 

Similarly, opting for near-colourless stones (G–H grades) often looks just as bright as higher grades in most settings. Prioritise an excellent cut, as this gives the most brilliance. Always buy from reputable diamond jewellers who provide certification from trusted labs such as GIA or IGI. This ensures transparency and helps you make an informed choice.

Among the 4Cs of diamond, you should prioritise cut quality first. A well-cut diamond reflects light in a way that maximises brilliance and fire, often making it appear larger and more beautiful than a bigger stone with lower cut quality.

After cut, you can balance colour and clarity. Many near-colourless and eye-clean diamonds offer excellent value without the high price of top grades. Carat weight should come last, chosen based on your size preference and budget, while ensuring the stone still has excellent sparkle.

There is no single “best” shape. The ideal diamond shape depends on your style, budget, and how you want the ring to look on your hand. Round brilliant diamonds are the most in-demand shape because of their exceptional sparkle and timeless appeal, but fancy shapes like ovals, emeralds, radiants, or cushions can offer a distinctive look and better value for money. 

Choosing the best shape often comes down to a mix of personal taste, finger shape, and lifestyle considerations.
