Choosing an engagement ring is an exhilarating journey filled with countless decisions. One of the most significant choices you'll make is selecting the diamond carat weight—the measure of a diamond's size. Carat weight has a significant impact on the overall appearance and cost of the ring, making it a crucial consideration for anyone embarking on this special quest.

Understanding the nuances of a diamond carat weight and its influence on the ring's aesthetic can help you create a symbol of love and commitment that perfectly reflects your partner's style and preferences. In this guide, we will explore the various aspects of diamond carat weight, giving you the knowledge and confidence to make an informed decision and find the ideal carat weight for your engagement ring.

Choosing the right diamond carat weight for an engagement ring is a personal decision that depends on various factors, including your budget, personal preferences, and the style you're looking for.



Determining a recommended budget for an engagement ring can be subjective and dependent on individual circumstances. Traditionally, it was suggested to spend around two to three months' salary on an engagement ring. However, it's important to note that this guideline is not set in stone and may not be applicable or feasible for everyone.

Instead, consider the following factors when setting a budget for an engagement ring:

  1. Assess your current financial situation, including income, expenses, and savings. Determine a budget that aligns with your overall financial goals and responsibilities. It's crucial to choose a ring that you can comfortably afford without causing financial strain.
  2. Consider your priorities and values as a couple. Some individuals may prioritise spending more on experiences, travel, or saving for the future rather than allocating a large portion of their budget to an engagement ring. It's important to have open and honest discussions with your partner to ensure your budget aligns with your shared values.
  3. Remember that the cost of an engagement ring is not solely determined by the diamond's size but also by other factors such as the cut, colour, clarity, and overall design. It's often recommended to prioritise quality over sheer carat weight to ensure you get a beautiful and well-crafted ring.
  4. Consider exploring alternative gemstones, different metal choices, or vintage/antique rings. These alternatives often offer unique and budget-friendly options without compromising beauty or significance.

Ultimately, there is no one-size-fits-all answer to setting a recommended budget for an engagement ring. It's important to balance your financial capabilities, personal preferences, and the meaning behind the ring. By considering these factors, you can establish a budget that suits your specific circumstances and allows you to choose a ring that symbolises your love and commitment.

Partner's Preference

When considering your partner's preferences before buying an engagement ring, there are several important factors to remember. While every individual is unique and may have specific preferences, here are some common aspects to consider:

  1. Pay attention to the type of jewellery your partner typically wears. Do they lean towards classic, vintage, modern, or minimalist styles? Observing their existing jewellery collection can provide valuable insights into their preferred ring aesthetics.
  2. Consider whether your partner prefers yellow gold, white gold, rose gold, platinum, or another metal. This choice can greatly impact the overall look and feel of the ring. It's helpful to take note of any metal preferences your partner may have mentioned or expressed interest in.
  3. The shape of the diamond or centre stone is an essential consideration. Popular options include round, princess, cushion, emerald, oval, and pear-shaped stones. If your partner has preferred a particular shape or admired a specific style, consider that.
  4. While carat weight is an important factor, it's not the sole consideration. Some individuals may prioritise quality over size, while others may have specific size preferences. Take note of any comments or hints your partner may have dropped regarding the desired size of the diamond or stone.
  5. Consider your partner's lifestyle and everyday activities. If they have an active lifestyle or work in a field where a large, prominent ring might not be practical, they prefer something more low-profile and comfortable.
  6. Some individuals prioritise ethical sourcing and sustainability when choosing a diamond or engagement ring. If this aligns with your partner's values, you may want to explore options such as lab-grown diamonds or ethically sourced gemstones.

Remember, communication is key. Discreetly gather information about your partner's preferences through casual conversations or seeking input from close friends or family members. Additionally, consider involving your partner in the ring selection process to ensure their tastes and preferences are met. Alternatively, opt for a proposal with a placeholder ring, allowing your partner to choose the final design together.


Finger Size 

When buying an engagement ring, considering the finger size of your partner is an important factor. Finger size can play a significant role in determining the ideal design and proportion of the ring. A larger finger size may require a larger carat weight to maintain a balanced and proportional appearance. In comparison, a smaller finger size may be better suited to smaller carat weights that exude elegance and delicacy.

It's essential to consider the size and shape of your partner's finger to ensure the ring sits comfortably and showcases the diamond or centre stone beautifully. By considering finger size alongside other preferences, you can select an engagement ring that complements your partner's hand and expresses your love in a way that feels truly personal and meaningful.

Ring Setting

The ring setting is a crucial aspect to consider when choosing an engagement ring, as it greatly influences the overall look and style of the ring. The setting refers to how the diamond or centre stone is placed and secured within the ring. Here are some popular ring-setting options to explore:

  1. The prong setting is one of the most classic and widely used settings. It features metal claws or prongs that hold the diamond in place while allowing maximum light to enter the stone for enhanced brilliance and sparkle. Prong settings can vary in the number of prongs, typically four or six, and can be crafted in different styles, such as rounded or pointed prongs.
  2. The halo setting is characterised by a ring of smaller diamonds or gemstones that encircle the centre stone. This setting not only adds extra sparkle and visual impact but also creates the illusion of a larger centre stone. The halo setting is a popular choice for those seeking a glamorous and eye-catching design.
  3. In a pavé setting, small diamonds are set closely together and held in place by tiny metal beads or prongs, creating a continuous "paved" appearance on the band or surrounding the centre stone. This setting style adds an extra layer of brilliance and can give the illusion of a larger, more luxurious ring.
  4. The channel setting features a row of smaller diamonds or gemstones within a channel carved into the band. This setting offers a sleek and sophisticated look while providing additional sparkle and protection for the stones.
  5. A bezel setting encircles the entire perimeter of the diamond or centre stone with a metal rim, holding it securely in place. This setting offers excellent protection for the stone and can create a modern, minimalist aesthetic.
  6. Vintage or antique settings showcase intricate and detailed craftsmanship from different eras, such as Art Deco or Victorian styles. These settings often feature unique designs, filigree work, and engraving, offering a touch of nostalgia and timeless elegance.

When selecting a ring setting, consider your partner's style and preferences. Some may prefer a classic and timeless look, while others gravitate towards more unique and contemporary designs. It's also worth considering how the setting will interact with your partner's lifestyle and daily activities to ensure comfort and durability.

By carefully choosing the ring setting, you can create an engagement ring that beautifully showcases the diamond or centre stone while reflecting your partner's individuality and capturing the essence of your love and commitment.

Diamond Size/Weight

Engagement rings come in various diamond sizes and weights, allowing couples to choose a ring that best suits their preferences and budget. The size and weight of a diamond are typically measured in carats, which is a unit of weight equal to 200 milligrams. When selecting a diamond for an engagement ring, it's important to consider factors such as personal style, budget, and the desired visual impact of the ring.

Diamond sizes range from tiny accent stones to large centre stones that make a bold statement. Here are some common diamond sizes and their general characteristics:


Accent Diamonds

These are small diamonds used to enhance the overall design of the ring. They are typically less than 0.10 carats and are often used as side stones or pavé accents. While they may not be the focal point of the ring, they add sparkle and complement the centre stone.


Budget £150 - £350

0.10 Diamond Size 2mm


0.25 to 0.50 Carats

0.25 to 0.50 diamonds are considered modest but can still create a beautiful and elegant look. They are a popular choice for those who prefer a more subtle and delicate appearance. These diamonds are often used as centre stones for solitaire rings or combined with smaller accent diamonds.


Budget £350 - £1800

0.25 Diamond Size 4mm 

0.50 Diamond Size 5mm 


0.75 to 1.00 Carats

Diamonds in this range are the most commonly chosen for engagement rings. They offer a good balance between size and affordability. These diamonds are noticeable and can create a stunning visual impact while being relatively budget-friendly.


Budget £1800 - £9000

0.75 Diamond Size 5.7mm

0.75 Diamond Size 6.5mm


1.50 to 2.00 Carats

For those who want a beautiful sparkle, the 1.50ct + diamonds in this size are considered larger and tend to make a significant impression. They are often chosen by individuals who desire a more substantial presence on their fingers. These diamonds are highly sought after and can be quite valuable.


Budget £9000 - £40000

1.50 Diamond Size 7.3mm

2.00 Diamond Size 8mm


2.00 Carats and above

Diamonds in this category are considered large and are chosen by those who desire a truly impressive and eye-catching ring. They create a bold statement and are often associated with luxury and extravagance. Larger diamonds of this size tend to be quite rare and valuable.

While carat weight affects the size of a diamond, other factors such as cut, colour, and clarity also contribute to a diamond's overall appearance and value. These factors determine the diamond's brilliance, sparkle, and how well it reflects light.


Quality over Size 

Remember that the overall quality of the diamond is just as important, if not more so, than the carat weight alone. Consider the other factors known as the "Four Cs": cut, colour, and clarity. A well-cut diamond with good clarity and colour can make a smaller-carat weight appear more brilliant and desirable.

Ultimately, it's important to find a balance between your budget, your partner's preferences, and the overall aesthetics of the ring. Consider consulting with a reputable jeweller who can provide guidance and show you various options within your desired carat weight range.
