Budgeting for an Engagement Ring

When shopping for an engagement ring, it's essential to start with a realistic budget in mind. Your budget sets the foundation for your entire selection process, and it's crucial to consider various factors that can affect the cost of an engagement ring. Whilst some believe an engagement ring should align with 1-3 months' salary, it's crucial to remember that every couple is unique. Craft a budget that aligns best with you and your partner. To get the most value within your chosen budget, here are some practical tips:

  • Consider the 4 C's: Before setting your budget, learn about the Cut, Colour, Clarity, and Carat (Weight) of the diamond, as these factors significantly influence the price. Make sure you understand how diamonds are graded to make an informed choice.

  • Balance Quality and Price: Strive to strike a balance between quality and price. You don't need to break the bank for a beautiful engagement ring that symbolises your love.

  • Personalisation Options: When selecting your perfect engagement ring, you'll also want to decide whether you want an off-the-shelf ring or something bespoke, created specifically with your love story in mind. An off-the-shelf ring provides convenience and a wide range of styles to choose from, whilst a bespoke ring allows you to design a unique piece that encapsulates your love story. Consider adding engravings to your engagement ring to make it even more special. Engravings can include special dates, meaningful words, or even motifs that hold significance in your relationship. These personal touches can add an extra layer of sentiment to your perfect engagement ring, making it a cherished piece of jewellery that beautifully symbolises your love.

Understand the 4 C’s of Diamonds


The cut of a diamond refers to the shape and facets, and it greatly affects a diamond's brilliance and sparkle. There are various diamond cuts, including round, princess, and emerald, each offering unique visual characteristics. When buying a diamond, knowing the different cuts and their impact on the overall look is crucial.


Clarity is all about the presence of internal and external flaws, known as inclusions and blemishes. A diamond with fewer imperfections is more valuable and tends to sparkle brilliantly. Understanding clarity and how it's graded is vital when selecting the perfect diamond.


Carat is a measurement of a diamond's weight, which directly impacts its size and, consequently, its value. Larger carat weight often leads to a more substantial price tag. Knowing the significance of carat weight in relation to size and value is essential when buying a diamond.


Diamonds are graded on a colour scale from D (colourless) to Z (light yellow or brown). The colour of a diamond can significantly influence its overall appearance and value. Learning about the colour scale and its impact on your perfect engagement ring is key.

4. Find Your Partner’s Ring Size

To ensure the engagement ring fits perfectly, it's crucial to discreetly determine your partner's ring size. To discreetly determine your partner's ring size, there are a few effective techniques you can employ. One option is to borrow a well-fitting ring from their jewellery collection and use it for measurement, or simply mark where it sits on your own finger for reference. Another approach is to enlist the help of their close family members or friends, who can subtly enquire about their ring size without giving away the surprise. Additionally, you can work the topic into a conversation in a natural and nonchalant manner, ensuring it doesn't raise any suspicion.
