The Ultimate Guide to Buying a Diamond Engagement Ring: Expert Tips and Tricks for Saving Time and Money.

Buying a diamond engagement ring can be an exciting but also overwhelming process, with so many options to choose from. Here is a guide to help you save time and money while finding the perfect diamond engagement ring:

Set a budget

It's important to decide on a budget before shopping for a diamond engagement ring. This will help narrow down your options and ensure that you are spending within your means. Keep in mind that the average cost of a diamond engagement ring is around £3,000, but you can certainly find options at a lower or higher price point.

It's a good idea to consider your overall financial situation and how much you can comfortably afford to spend on a diamond engagement ring. Don't feel pressure to spend more than you can afford, as there are plenty of beautiful and affordable options available.

Choose a diamond shape

There are many different diamond shapes to choose from, including round, princess, oval, cushion, pear, emerald, and more.

Consider your partner's personal style and what shape they may prefer. Round diamonds are the most popular choice for diamond engagement rings, but other shapes can be just as beautiful and often come at a lower price point.

For example, oval and cushion cut diamonds can be a more budget-friendly option while still having a stunning appearance.

Understand the 4C's of diamonds

The 4C's refer to the cut, colour, clarity, and carat weight of a diamond. These factors all play a role in the overall quality and value of your diamond.


The cut of a diamond refers to the way it is shaped and how well it reflects light, which affects its overall sparkle and brilliance.

A diamond with an Excellent cut will reflect light back to the viewer's eye, creating the illusion of a larger and more sparkling diamond.

The most common cuts for diamonds are round, princess, oval, pear, radiant, emerald, marquise and cushion.

Of the Four Cs - cut, colour, clarity, and carat weight - the cut is often seen as the most important factor in determining the overall quality and value of a diamond.

This is because the cut determines how well a diamond reflects light and how much it sparkles, which is one of the main appeals of a diamond.

There are several factors that go into a well-cut diamond, including the table percentage,  depth percentage and angle of the cut, the symmetry and proportion of the facets, and the polish of the diamond.

A diamond with an excellent cut will have a balance of depth and angles, symmetrical and evenly sized facets, and a pleasing overall shape.

The cut of a diamond is graded on a scale from excellent to poor. Diamonds with a higher cut grade will have better light performance and will be more valuable, while diamonds with a lower cut grade may have a less desirable appearance and be less valuable.

When choosing a diamond, it's essential to consider the cut grade and ensure that it is as high as possible.

It is worth noting that Round Brilliant is the only diamond shape that is given a cut grade. Other diamond shapes, such as princess, emerald, pear, and oval, are only given a polish and symmetry grade.


Diamonds are graded on a scale from D (colourless) to Z (light yellow).

Diamonds that are colourless (D-F) tend to be more valuable. It's important to note that the colour of near colourless grades (G-J) may not be noticeable to the naked eye, so you may be able to save money by choosing a slightly lower colour grade without sacrificing appearance for your diamond.

when choosing a diamond for a yellow gold setting, it is generally recommended to choose a diamond with a colour grade near colourless (G-J).

This is because diamonds have the ability to reflect the colours around them, and if the diamond is set in yellow gold, it may pick up some of the yellow colour from the metal.


Clarity refers to the presence of inclusions (imperfections) within the diamond.

Diamonds with fewer and smaller inclusions are generally more valuable. The clarity scale ranges from Flawless (no inclusions visible under 10x magnification) to Included (significant inclusions visible to the naked eye).

Again, it's important to keep in mind that inclusions may not be noticeable to the naked eye, so you may be able to save money by choosing a slightly lower clarity grade without affecting the overall appearance of the diamond.

One clarity grade that is often considered budget-friendly and still offers good appearance is VS (Very Slightly Included).

Diamonds with a VS clarity grade have inclusions that are difficult to see under 10x magnification, and they are generally considered "eye clean" (meaning that the inclusions are not visible to the naked eye).

This makes them a good choice for those who want a high-quality diamond without breaking the bank.

It is worth noting that the visibility of inclusions can also depend on the size of the diamond and position of the inclusion.

For example, a larger diamond may have inclusions that are more visible, even if the clarity grade is high.

Similarly, inclusions that are located near the centre of the diamond may be more visible than inclusions that are located on the edges of the diamond.

Carat weight:

The carat weight of a diamond refers to its size. A larger diamond will generally be more expensive than a smaller one, all else being equal.

It is generally true that diamonds with similar size and measurements can have different carat weights and prices. 

For example, a diamond that is slightly under one carat, like 0.90 carats, can have a similar or even larger diameter and appearance to a diamond that is one carat.

Similarly, a diamond that is slightly under two carats, like 1.9 carats, can have a similar diameter and appearance to a diamond that is just over two carats, like 2.1 carats.

In these cases, you may be able to save money by choosing the diamond with the lower carat weight, as long as the size and measurements are similar.

For example, if you are considering two diamonds, one that is 0.90 carats and one that is 1.00 carats, and both have similar size and measurements, you may be able to save money by choosing the 0.90 carat diamond.

However, it's important to consider the other 3C's as well, as a smaller diamond with a higher cut, clarity, and colour grade may actually have a higher value than a larger diamond with a lower grade in these areas.

Beyond the 4C's of a diamond

When it comes to diamonds, the Four C's are the most commonly known factors that determine a diamond's value and quality.

But there are many other factors that can also affect a diamond's appearance and value.

The diamond girdle:

One of these factors is the diamond girdle, which is the outermost edge of a diamond.

The girdle can be thin, thick, or somewhere in between, and its size and shape can affect the way the diamond looks when viewed from the top. A thin girdle can make the diamond appear larger, while a thick girdle can make it appear smaller.


Fluorescence is another factor that can impact a diamond's perceived colour. Fluorescence is the emission of light by a substance when it is exposed to UV light, and some diamonds have fluorescence that can cause them to appear hazy or milky in certain lighting conditions.

While fluorescence is not necessarily a negative quality, it can affect the appearance of a diamond and may impact its value.

Polish and polish lines:

Polish lines are also important to consider when evaluating a diamond. The polish of a diamond refers to the finish on its surface, which should be smooth and even.

Polish lines are small, faint lines that can sometimes be seen on the surface of a diamond, and they are a result of the diamond cutting process.

While polish lines are not necessarily a sign of a poorly cut diamond, they can affect its appearance and value.

Certain types of inclusions: 

Inclusions are defects or imperfections found within a diamond, and they can take many different forms. Some inclusions, such as feathers and clouds, are relatively common and may not have a significant impact on the diamond's value.

Other inclusions, such as chips and cracks, can be more serious and can significantly reduce the value of a diamond.

When shopping for a diamond, it is important to look for inclusions that are not visible to the naked eye, as these are less likely to affect the diamond's appearance.

As you can see, there are many factors beyond the Four C's that can impact a diamond's appearance and value.

When shopping for a diamond, it's important to consider all of these factors to ensure that you are getting the best quality and value for your money.

Consider metal choices

The metal that the diamond is set in can also affect the overall look and cost of the diamond engagement ring.

Popular choices include platinum, white gold, yellow gold, and rose gold.


Is a white metal that is often used in engagement rings. It is a dense, heavy metal that is highly durable and resistant to wear and tear. Platinum is also hypoallergenic, making it a good choice for people with sensitive skin.

However, platinum is a more expensive option than other metals, and it requires regular cleaning and maintenance to keep it looking its best.

White gold

Is another popular choice for engagement rings. It is created by mixing gold with white metal alloys, such as palladium or nickel, and then plating the resulting metal with rhodium to give it a bright white finish.

White gold is more affordable than platinum, but it may require more frequent rhodium plating to maintain its bright white colour. Some people with sensitive skin may also have an allergic reaction to the metal alloys used to create white gold.

Yellow gold

Is a classic choice for engagement rings. It is made from pure gold, which is a soft, yellow metal. Yellow gold is relatively affordable, but it is not as durable as platinum, so it may require more frequent maintenance.

Rose gold

also known as pink gold or red gold, is made from a mixture of gold and copper. It has a warm, rosy colour that is popular in engagement rings. Like yellow gold, rose gold is relatively affordable, but it is not as durable as platinum. It may require more frequent maintenance.

When choosing an engagement ring metal, it's important to consider your partner's personal style and skin tone.

Some people find that certain metals look better on their skin tone than others.

For example, people with warm skin tones may prefer yellow gold or rose gold, while people with cool skin tones may prefer platinum or white gold.

It's also important to consider the durability and maintenance requirements of the different metals to make sure you choose a ring that will stand the test of time.

Lab-grown Vs Natural Diamonds

Lab-grown diamonds are a newer and increasingly popular option for those looking for a diamond.

Lab diamonds are created in a laboratory setting using advanced technology that replicates the natural diamond formation process.

Lab-grown diamonds are chemically, physically, and optically identical to natural diamonds, but they are typically more affordable and have a lower environmental impact.

One of the main advantages of lab-grown diamonds is their price.

Lab made diamonds are typically less expensive than natural diamonds, making them a more budget-friendly option for those looking for a high-quality diamond without breaking the bank.

Lab-grown diamonds can also be an excellent choice for those who want to reduce their environmental footprint, as they are produced in a controlled laboratory setting rather than being mined from the earth.

In addition to their affordability and environmental benefits, lab-grown diamonds offer many of the same qualities as natural diamonds.

They are chemically, physically, and optically identical to natural diamonds, meaning they have the same hardness, sparkle, and brilliance as natural diamonds. Lab-grown diamonds are also available in a range of cuts, colours, clarities, and carat weights to suit every preference and budget.

Natural diamonds

Natural diamonds are a traditional and highly sought-after choice for jewellery, particularly for engagement rings.

Mined diamonds are formed over millions of years deep beneath the earth's surface through a process of extreme temperature and pressure.

The unique characteristics of each natural diamond, including its cut, colour, clarity, and carat weight, are determined by the conditions under which it was formed.

One of the main appeals of natural diamonds is their perceived value and prestige.

Natural diamonds are considered rare and are often seen as a symbol of wealth and success.

Earth mined diamonds are also prized for their timeless beauty and the way they reflect light, creating a stunning sparkle and brilliance.

In addition to their beauty and perceived value, natural diamonds also have a rich history and cultural significance.

For centuries, diamonds have been revered for their unique properties and have been used in jewellery and other decorative objects. Diamonds have also played a role in various cultural traditions and rituals, such as engagement and wedding ceremonies.

It's important to note that not all natural diamonds are created equal, and their value can vary significantly based on their quality and other characteristics.

When choosing a natural diamond, it's essential to consider the Four Cs - cut, colour, clarity, and carat weight - as well as the source of the diamond and its ethical and sustainable practices.

Make sure to do your research and choose a reputable Jeweller that offers high-quality natural diamonds that have been ethically and sustainably sourced and certified by reliable lab.

Certification and peace of mind

When it comes to purchasing a diamond, it is important to choose a diamond that has been graded by a reputable organisation like the Gemological Institute of America (GIA) or the International Gemological Institute (IGI).

These organisations have strict grading standards and are known for their accuracy and consistency, which can give you peace of mind when making such a significant purchase.

How Do I Know My Partner's Ring Size?

There are a few ways you can determine your partner's ring size:

Ask them directly: This is the most straightforward approach, but it may not be an option if you want to keep the ring a surprise.

Check their jewellery box: Look for rings that your partner currently wears on their ring finger and use a ring sizer or a ring size chart to determine their size.

Ask a friend or family member: If you have a close friend or family member who is close to your partner, they may be able to help you determine your partner's ring size.

When choosing a diamond engagement ring, it is important to consider your personal preferences and budget.

You may want to prioritise certain factors, such as colour or clarity, depending on your personal style and the look you are trying to achieve.

It is also a good idea to work with a reputable jeweller who can help you find the perfect diamond for your needs and preferences.
