Engagement Ring Buyer’s Guide

The process of choosing an engagement ring is simpler than you might think. Our ultimate engagement ring buying guide will take you through every step on how you can get the perfect ring with ease.

Choosing a diamond

Putting the time and consideration into choosing the perfect diamond for you or your loved one is the ultimate romantic gesture. Whether you’re browsing diamonds online or in-store, understanding the 4Cs – cut, colour, clarity and carat weight – is crucial. The cut determines brilliance, the colour ranges from colourless to light hues, clarity measures internal flaws and carat weight reflects size. Additionally, selecting the perfect shape, from classic round to elegant emerald, will influence the ring's style and appearance. Balancing these factors ensures you find the ideal diamond that fits your budget and preferences.

Diamond Shapes & Cut

Diamonds can be cut into a wide variety of shapes, each possessing a unique character and its own way of emitting bright and lustrous sparkle. From classic rounds to contemporary Asscher cuts, find your diamond shape with the handy guide below.

The 4Cs Diamond Fundamentals

When choosing a diamond, understanding the 4Cs – cut, colour, clarity, and carat weight – is essential. These four characteristics determine a diamond's quality and value. Discover these fundamentals to select the perfect diamond that meets your expectations and budget.

Ring Guide

Diamond 4Cs

Learn about the 4 main characteristics that amount to a diamond's beauty; from the quality of its cut, colour, clarity and its carat weight.

Diamond Cut

A top grade is well worth prioritising for optimal sparkle, symmetry and all-round exquisite aesthetics. This is one to prioritise.

Diamond Colour

A very visible characteristic, it's important to also prioritise a top colour grade to avoid a yellowish, brownish or greyish diamond. 

Diamond Clarity

A characteristic you can compromise on if you wish; the visible difference flawless and very slightly included diamonds in tiny.

Diamond Carat

Although important, first prioritise cut and clarity to ensure a beautiful gem before seeing the carat size your budget can afford. 

Cut
The cut of a diamond significantly influences its brilliance and sparkle. A well-cut diamond reflects light beautifully, enhancing its overall appearance. The cut is graded from Excellent or Ideal to Poor. GIA use the term ‘Excellent’ while IGI use ‘Ideal’ to describe optimal cut. The precision of the cut impacts how light interacts with the diamond, creating that captivating shimmer. Learn more about diamond cuts.

Colour
Diamond colour is graded on a scale from D (colourless) to Z (yellowish or brownish). Top-grade colourless diamonds are the rarest and most valuable. Stick with D to F for a colourless diamond; any lower and you’ll notice undesirable tints. ‘Fancy coloured’ diamonds, such as yellow, blue or pink, are graded differently. Learn more about diamond colour.

Clarity
Clarity refers to the presence of internal or external flaws, known as inclusions and blemishes. Diamonds are graded from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions visible to the naked eye). Higher clarity grades are rarer and more valuable. Choose anything above Very Slightly Included for inclusions invisible to the naked eye. Learn more about diamond clarity.

Carat Weight
Carat weight measures a diamond's weight and therefore correlates to how big the diamond looks. Larger diamonds are rarer and thus more valuable. However, carat weight should be balanced with the other Cs to ensure the best overall quality and appearance. Take two diamonds of the same carat weight: a Poor cut might look larger but will lack brilliance and sparkle, whereas an Excellent cut diamond will display optimal brilliance. Learn more about diamond carat weight.

By understanding the 4Cs, you can make an informed decision and find a diamond that perfectly matches your needs and desires. Explore more about each fundamental aspect of diamonds through our detailed guides.

Ring Metals

Rings are crafted in a selected range of fine and precious metals: platinum, yellow gold, rose gold and white gold. Each metal offers its own unique aesthetic and qualities, influencing the overall look and style of the ring. Understanding the characteristics of each metal will help you choose the perfect setting for your diamond.

Platinum
Platinum is a rare and durable metal, known for its natural white sheen that does not tarnish over time. Its strength makes it an excellent choice for secure settings, and its hypoallergenic properties are ideal for those with sensitive skin. Platinum's luxurious feel and enduring quality make it a popular choice for engagement rings.

Yellow Gold
Yellow gold offers a timeless and classic appeal, characterised by its warm, rich hue. Available in 18k, yellow gold is both beautiful and durable. Its traditional look complements vintage and classic ring styles, making it a favourite for those who appreciate a classic aesthetic. Yellow gold has had a resurgence in popularity in recent years.

Rose Gold
Rose gold is renowned for its romantic blush hue. Created by alloying gold with copper, this metal has a unique colour that adds a modern twist to traditional designs. Rose gold's warm and flattering tone makes it an appealing choice for those seeking something distinctive and elegant.

White Gold
White gold is a popular alternative to platinum, offering a similar silvery-white appearance. Created by alloying gold with white metals like palladium or silver, white gold is typically plated with rhodium to enhance its shine and durability. It’s a versatile metal that complements various diamond shapes and styles. Be aware that white gold needs replating every so often, as the rhodium fades to reveal a yellowish tint.

Choosing the Right Ring Size

Selecting the perfect ring size is crucial to ensure a comfortable and secure fit, but rest assured that at Queensmith we offer free resizing up to 3 times, up to 3 sizes on engagement rings. Ring sizes are measured in the UK by alphabetical letters, from A to Z+. The average women's ring finger size is L, and men's T. Discover how you can gauge yours or your partner's ring size below.

How to find their ring size

Whether you’re planning a surprise proposal or shopping together, knowing the correct size will make the moment even more special. Here’s a brief overview of how to find the ideal ring size, with expert tips to help you along the way.

  1. Find one of their existing rings: Borrow a ring they won't miss and have it measured by a jeweller, but be aware that each of our fingers measure differently so you’ll need something they wear on their ring finger. Alternatively, use Queensmith’s downloadable Ring Sizer Guide to measure it at home.

  2. Ask friends or family: Enlist help from friends or family who can casually find out the size by bringing up ring sizes in conversation.

  3. Ask your married or engaged friends for help: Have friends let your partner try on their ring or casually discuss ring preferences to gather size information.

  4. Ask an expert: The easiest way to find your partner’s ring size is to have your jeweller estimate. All we need is their height and clothes size to make a solid estimation. And remember, we offer free resizing if it’s slightly out!

For detailed tips, check out our guide:

Ring size is directly correlated to our height and clothing size, so if you know these details about your partner, we’ll be able to make a very good estimation!

Setting the Budget

Understanding how much diamonds, gemstones and the metalwork of your ring cost should give you a good idea of what will work for you and your personal budget. Setting a realistic budget is crucial to ensure you get the best value without compromising on quality.

Several factors influence the cost of an engagement ring. The 4Cs – cut, colour, clarity, and carat weight – are crucial, with higher quality and larger diamonds commanding higher prices. Gemstones, such as sapphires, emeralds, and rubies, vary in cost based on their type, quality and size. Additionally, the complexity of the design, including custom settings, intricate details and extra features like hidden halos or an engraving, can increase the overall cost. By understanding these factors, you can set a realistic budget that aligns with your financial plans and preferences.

What factors influence the cost of the engagement ring?

This pie chart breaks down the average cost of an engagement ring and presents how expenses are distributed among key components to help inform your decision-making when considering budget allocation for this meaningful purchase. Factors such as a complex design, or diamonds set along the ring's band will increase the cost.

  • Trilogy: £1,375 (including two side stones around 0.10ct each)

Diamond Prices

Diamonds vary in price depending on size and quality. The bigger and better the quality of the diamond, the higher the price. Diamonds can start from as little as £600 and go up into thousands and tens of thousands. For instance, the price of a natural 1 carat diamond is typically between £5,500 and £10,000 for a diamond that is optimal quality, or more like £1,500 for a lab diamond. Learn more about 1ct engagement ring prices and cuts in our buying guide.

To find the best value diamond, consider balancing the 4Cs to meet your budget and quality expectations. Prioritising a high-quality cut can maximise brilliance, even if you compromise slightly on colour and clarity. Lab grown diamonds offer excellent value, often costing 60-80% less than natural diamonds of similar quality. Additionally, choosing a diamond just under a key carat weight (e.g. 0.9 carats instead of 1 carat) can significantly reduce the price while maintaining a similar visual impact.

For more detailed guidance, explore our Diamond Cost Guide.

Understanding price ranges can help you set a realistic budget and find the perfect diamond that meets your needs and preferences. Here’s a quick reference table to illustrate how diamond prices can vary:

Carat Diamond Price Range
0.30ct Natural Diamond £650 – £1,000
Lab Diamond £500 – £550
0.50ct Natural Diamond £1,200 – £2,400
Lab Diamond £750 – £900
1.00ct Natural Diamond £3,100 – £8,650
Lab Diamond £1,550 – £1,700
1.50ct Natural Diamond £7,400 – £15,950
Lab Diamond £2,650 – £3,000
2.00ct Natural Diamond £10,700 – £30,200
Lab Diamond £3,800 – £4,400

Lab Grown Diamond Prices

If you’re aiming for a larger diamond size with a tighter budget, consider lab grown diamonds. A lab diamond typically retails 60% to 80% cheaper than natural diamonds thanks to the efficiency of their production, all the while appearing identical to their natural counterparts.

Lab grown diamonds are created using advanced technological processes that replicate the conditions under which natural diamonds form. These diamonds are chemically, physically and optically identical to natural diamonds but come at a fraction of the cost.

For example, for a top quality 1 carat lab diamond, you could be looking at prices as low as £1,500 (compared to £5,500 plus for a natural diamond). This significant price difference allows you to choose a larger or higher-quality diamond within the same budget.

By considering lab grown diamonds, you can achieve the sparkle and elegance you desire while staying within your budget. For more detailed information, explore our guides on Lab Diamonds vs Natural Diamonds and Lab Grown Diamonds Price & Value.

Lab grown diamonds offer a cost-effective alternative to natural diamonds. They provide the same brilliance and beauty, allowing customers to get a larger or higher-quality stone for their money.

Tips for Choosing the Right Engagement Ring

Choosing the perfect engagement ring is a significant decision, and knowing where to start can make the process smoother. Here are five essential tips to guide you in selecting a ring that will be cherished for a lifetime.

#1: Learn where the stone came from (ethical sourcing)

Understanding the backstory of your diamond is crucial. Ethically sourced stones ensure that your diamond has been mined and processed in a manner that respects both human rights and the environment. Queensmith is committed to ethical sourcing, utilising a trusted supply chain to ensure transparency and high-quality standards. Additionally, lab grown diamonds offer a guaranteed ethical option, as they are created in controlled environments without the environmental and social impacts of traditional mining. By choosing an ethically sourced or lab grown diamond, you can feel confident about the origins of your precious stone.

#2: Free ring resizing

When planning a surprise proposal, getting the ring size exactly right can be challenging. At Queensmith, we understand this, which is why we offer complimentary resizing for all our customers. This ensures that your ring fits perfectly after the proposal, allowing you to focus on the moment rather than worrying about the fit. For more details on finding the right ring size, explore our guide on How to Find Your Partner’s Engagement Ring Size.

#3: Match your engagement ring to a wedding band

Thinking ahead about how your engagement ring will pair with a wedding band can help ensure a cohesive and stylish look in the long run. Whether you prefer a matching set or a complementary style, considering the combination early on will make future decisions easier. Matching your engagement ring with your wedding band ensures that both rings look harmonious when worn together. For more information, read our in-depth guide on How to Wear Your Engagement Ring.
