Buying an engagement ring is one of the most important purchases you will ever make. It represents commitment, intention, and a personal story that will be worn every day for a lifetime. Because of that, it deserves careful consideration rather than rushed decision-making.
We’ve helped couples across London and the UK find engagement rings that feel personal, meaningful, and timeless. Regal's engagement ring buying guide has been created to give you clear, honest and practical information so you can make a confident and informed choice, whether you are buying your first ring or designing something completely bespoke.
Choosing an engagement ring starts with understanding what matters most to you as a couple. Before selecting a diamond shape or engagement ring style, focus on three key factors: budget, lifestyle, and personal taste.
Budget helps narrow down realistic options, but it should never feel restrictive or confusing. Lifestyle is equally important because an engagement ring is worn daily; someone with an active lifestyle may prefer a lower-set design for durability, while others may prioritise a more elevated setting. Finally, personal taste ensures the ring reflects individuality rather than trend.
Once these three areas are clear, choosing the right engagement ring becomes far more straightforward, enjoyable, and personal.
For engagement rings, the diamond is the centrepiece and naturally the first place to start. Choosing the right diamond is about finding the perfect balance between beauty, quality, and value.
When browsing diamonds, understanding of the 4Cs: cut, colour, clarity and carat weight is essential. These four factors form the foundation of diamond quality and allow you to compare different stones with confidence, ensuring you are investing in what truly matters rather than features that may not be visible to the naked eye.
Alongside quality, the shape and cut of the diamond plays a key role in defining the overall look of the ring. The right combination of shape and quality can significantly influence how the diamond appears, often making it look larger, brighter or more refined.
By considering everything from diamond quality and shape to overall stone choice and budget, you can make a well-informed decision and create an engagement ring that feels both meaningful and entirely personal.
Cut is widely considered the most important of the 4Cs, as it directly influences how a diamond interacts with light. A well-cut diamond reflects light beautifully, creating the brilliance, fire, and sparkle that make it so captivating.
Even a larger diamond can appear dull if the cut is poor, which is why cut quality should always be prioritised and never compromised.
Colour refers to how colourless a diamond appears and is graded on a scale from D (completely colourless) to Z (light yellow or warm tones). The highest-grade diamonds are completely colourless, while others may display subtle warmth.
In reality, these differences are often very slight and typically only noticeable when diamonds are compared side by side. A well-chosen near-colourless diamond can therefore offer excellent value without any visible compromise.
Clarity refers to the presence of natural inclusions within a diamond, formed during its creation deep within the earth. In most cases, these inclusions are microscopic and not visible to the naked eye, particularly in carefully selected stones.
For this reason, many buyers choose diamonds that are considered “eye-clean” rather than flawless, as they offer excellent value without compromising on appearance. When balancing quality and budget, understanding the relationship between diamond carat vs clarity can help you make a more informed decision.
Carat refers to the weight of a diamond and is often associated with its size. However, carat alone does not determine how large a diamond appears. Two diamonds of the same carat weight can look noticeably different depending on their cut and proportions.
The way a diamond is cut, along with its shape, can significantly influence its visual size and overall presence. If you are looking to maximise visual impact, exploring how to make a diamond look bigger can be especially helpful. For this reason, carat should always be considered alongside the other three Cs to ensure a balanced and beautiful result.
Once the diamond is selected, the next step is choosing the setting style. This is where the character of the ring truly takes shape. The setting influences not only how the diamond is presented, but also how the ring feels to wear every day.
It determines how much light enters the diamond, how secure the stone is, and how prominently it sits on the finger. A well-chosen setting can enhance the diamond’s brilliance, make it appear larger, or create a balanced overall look. Subtle design details such as the height of the setting, the thickness of the band, and the type of claws or prongs all contribute to both aesthetics and practicality.
Taking the time to explore different ring styles and settings can make a significant difference when choosing an engagement ring. It helps ensure the ring feels comfortable, suits everyday wear, and reflects the wearer’s personal style for years to come. Let’s take a look at some of the most popular engagement ring styles.
A solitaire ring features a single centre diamond, making it the most classic and timeless style. Its simplicity allows the diamond to take full focus, which is why the quality of the stone particularly the cut is so important. Different settings within solitaire designs, such as four or six claws, can subtly change the look, from modern to more traditional. Solitaire rings are also highly practical, easy to maintain, and pair seamlessly with almost any wedding band, making them a reliable long-term choice.

A halo setting surrounds the centre diamond with a circle of smaller diamonds, increasing sparkle and enhancing the perceived size of the centre stone. This style is ideal if you want maximum brilliance and a more eye-catching look. Halo designs can vary from delicate and refined to bold and statement-making, depending on the size and number of surrounding stones. However, because of the additional detail, halos can require slightly more cleaning to maintain their sparkle.
To understand how this compares with more minimal designs, read our guide on solitaire vs halo engagement rings.
Trilogy rings feature three stones, often symbolising the past, present, and future of a relationship. The centre stone is typically the largest, with two side stones adding balance and presence. This style offers more finger coverage than a solitaire, making it appear larger overall. It also allows for subtle customisation, such as using different diamond shapes or adding coloured gemstones to the side stones for a more personal touch.
In diamond band style, smaller diamonds are set along the band to add continuous sparkle. This enhances the overall brilliance of the ring and creates a more luxurious feel without overpowering the centre stone. The band can be set in different ways, such as pavé (closely set stones) or channel setting (stones set within the band for added protection). While visually striking, it’s worth considering that smaller diamonds may require occasional maintenance over time, especially with everyday wear.
A hidden halo adds a row of small diamonds beneath the centre stone rather than around it. From above, the ring appears like a classic solitaire, but from the side, it reveals an extra layer of sparkle. This makes it ideal for those who prefer a clean, minimal look with a subtle design detail. It can also enhance the appearance of the centre stone without changing its overall shape or style.
Meaning “you and me,” toi et moi design features two centre stones set side by side, representing two individuals coming together. It’s a highly symbolic and increasingly popular style, particularly for those looking for something unique. The stones can be matched for symmetry or intentionally different in shape or size for contrast. This flexibility makes it a great option for a more personalised and distinctive ring.
Cluster rings are made up of multiple smaller diamonds grouped together to create the look of a larger centrepiece. This style offers excellent visual impact and can be a more cost-effective way to achieve a bigger look. Cluster designs often have a vintage or decorative feel, but can also be designed in more modern layouts. Because of the multiple stones, they reflect light in different directions, creating a lively and unique sparkle.
If you’re still deciding which direction feels right, our full guide to popular engagement ring styles in London explores these options in more detail and can help you narrow down your preferences. Ultimately, the right style is one that reflects personal taste while remaining comfortable and practical for long-term wear. Trends will always evolve, but a well-chosen design should feel just as relevant years from now as it does today.
The choice of metal plays a crucial role in both the appearance and longevity of an engagement ring. Each metal offers its own advantages in terms of durability, colour, maintenance and overall character, so understanding the differences can help you make a more informed decision.
Platinum is widely regarded as one of the finest choices for engagement rings due to its exceptional durability and naturally white finish. It is a dense and hard-wearing metal, making it particularly suitable for everyday wear and ideal for securely holding diamonds in place over time. Its strength and longevity make it a popular choice for those looking for engagement rings.
White gold offers a similar bright and contemporary appearance to platinum but with a lighter weight. It is created by alloying yellow gold with white metals such as palladium or silver, and is usually finished with a rhodium plating to enhance its shine and whiteness. Over time, this plating may wear down, meaning the ring may require occasional re-plating to maintain its original look.
Yellow gold is the most traditional choice for engagement rings and has been used in jewellery for centuries. Its warm, rich tone gives it a classic and timeless appeal that works particularly well with a wide range of diamond shapes and settings. Yellow gold is naturally resistant to tarnish and corrosion, making it a reliable option for long-term wear.
Rose gold offers distinctive soft pink hue and romantic feel. It is created by blending gold with copper, which gives it both its colour and added strength. Its warm tone can be particularly flattering on a variety of skin tones and pairs well with both modern and vintage-inspired designs. Rose gold offers a balanced and stylish alternative.

Getting the ring size right is an important part of the buying process, especially when planning a surprise proposal. While it can feel challenging, there are several reliable ways to estimate size without giving anything away.
Borrowing a ring that is already worn on the correct finger is one of the most accurate methods. Alternatively, friends or family members may be able to help discreetly. Professional jewellers can also make informed estimates based on general information such as height and build or a hand picture.
It is worth remembering that resizing is usually possible after purchase, so perfection at this stage is not essential. Most jewellers offer resizing services to ensure a comfortable and secure fit.

There is no fixed rule or correct formula for how much should be spent on an engagement ring. Traditional guidelines such as “three months’ salary” are outdated and do not reflect modern buying habits or financial realities.
Instead, the right budget is one that feels comfortable and sustainable. What matters most is how the budget is allocated across the key elements of the ring. For example, prioritising cut quality over size often results in a more visually impressive diamond, even at a lower carat weight.
The choice between natural and lab-grown diamonds also has a significant impact on the budget. Lab-grown diamonds typically offer greater size and quality for the same price point, while natural diamonds are valued for their rarity and natural origin. Both are real diamonds, and neither is objectively better, it comes down to personal preference.
One of the most common decisions today is whether to choose a natural or lab-grown diamond. Both are chemically and optically identical, meaning they have the same physical structure, brilliance and durability.
Natural diamonds are formed over millions of years beneath the earth’s surface and are valued for their rarity and geological origin. Lab-grown diamonds, on the other hand, are created in controlled environments using advanced technology that replicates natural conditions.
The key difference lies in origin and price rather than appearance. Lab-grown diamonds often allow buyers to access larger or higher-quality stones within the same budget, while natural diamonds continue to appeal to those who value traditional rarity and long-term perception.

Choosing where to buy an engagement ring is just as important as choosing the ring itself. In the UK, buyers typically have three main options: independent jewellers, high street chains, and online retailers. Each option offers a different experience, so the right choice depends on your preferences, budget, and level of guidance you need.
Independent jewellers, particularly in areas like Hatton Garden, are often preferred for their expertise and personalised service. They usually offer higher levels of craftsmanship, the ability to customise designs, and the opportunity to view diamonds in person before buying. For a more tailored experience, visit Regal in Hatton Garden to view diamonds in person, explore bespoke designs, and receive expert guidance when choosing the perfect engagement ring.
High street jewellers provide convenience and ready-made designs that can be purchased quickly. This can be suitable if you are looking for a simple and straightforward option.
Online retailers tend to offer competitive pricing and a wide selection of styles. However, buying online means you rely on images and specifications rather than seeing the ring physically, so it is important to choose a trusted and reputable seller.
When selecting an engagement ring, it is important to think beyond initial appearance. A well-chosen ring should feel balanced in design, comfortable to wear and suitable for everyday life. For a more structured approach, you can also follow a complete engagement ring checklist to make sure no important detail is overlooked during the process.
It is always advisable to focus on cut quality first, as this has the greatest influence on beauty and brilliance. It is also worth considering how the ring will pair with a future wedding band, as both are typically worn together.
Most importantly, take time with the decision. An engagement ring is not just a purchase; it is a long-term symbol, and the right choice is one that continues to feel meaningful years after the proposal.
