How to choose the perfect engagement ring

Choosing an engagement ring is one of the most meaningful purchases you’ll ever make. More than just a piece of jewellery, it symbolises love, commitment, and the beginning of a new chapter together. With so many styles, stones, and settings to consider, the process can feel overwhelming — but with the right knowledge, it can also be joyful, exciting, and deeply personal.

This guide will walk you through everything you need to know, from diamond quality and ring styles to budgeting, metals, and custom designs — so you can buy with confidence and heart.

1. Set a Thoughtful Budget

There are no strict rules about how much you “should” spend. What matters most is finding a ring that reflects your love while fitting comfortably within your finances. Keep in mind the cost of the setting, the stone, and any future adjustments such as resizing or insurance.

2. Understand the 4 Cs of Diamonds

If you’re considering a diamond, it helps to know the 4 Cs — the standard factors that define quality:

  • Carat: The weight of the diamond, not its size. Bigger isn’t always better.

  • Cut: The most important factor, as it determines brilliance and sparkle.

  • Clarity: Refers to natural inclusions; most are invisible to the naked eye.

  • Colour: Graded from D (colourless) to Z (light yellow). Most people choose near-colourless for best value.

✨ Tip: Prioritise cut, then balance colour and clarity to get the most sparkle for your budget.

3. Explore Gemstone Options

Diamonds are classic, but they’re not the only choice. Sapphires, emeralds, and rubies have long been cherished in engagement rings, while moissanite offers brilliance at a lower cost. Think about your partner’s personal style — do they love timeless elegance, or do they prefer something colourful and unique?

4. Choose a Setting & Style

The setting shapes the entire look of the ring. Popular choices include:

  • Solitaire: A single stone — timeless, elegant, and understated.

  • Halo: A central gem surrounded by smaller diamonds for extra sparkle.

  • Three-Stone: Representing past, present, and future.

  • Vintage: Inspired by antique designs, often with intricate detail.

  • Modern: Sleek, minimalist styles with clean lines.

5. Select a Metal

The metal enhances both appearance and durability. Choices include:

  • Platinum: Naturally white, durable, and hypoallergenic.

  • White Gold: Bright and versatile, often rhodium-plated.

  • Yellow Gold: Classic and warm.

  • Rose Gold: Romantic and on-trend.

  • Palladium: Lightweight and tarnish-resistant.

6. Find the Right Ring Size

If the proposal is a surprise, discreetly borrow one of their rings (from the correct finger) or ask a trusted friend or family member. Resizing is possible, but some designs — like eternity bands — may be more difficult to adjust.

7. Choose a Trusted Jeweller

Your jeweller should offer excellent customer service, transparent pricing, and certified stones. Ask about warranties, resizing, returns, and whether the diamond or gemstone comes with a grading report (such as GIA or IGI).

8. Consider a Bespoke Design

For a ring that’s truly one of a kind, you might choose to work with a jeweller to create a custom design. Bespoke rings allow you to add sentimental details, personal touches, or a design that perfectly reflects your partner’s style.

9. Protect Your Investment

Once you’ve chosen the ring, don’t forget to insure it. Jewellery insurance can often be added to your home policy or arranged through a specialist provider, ensuring peace of mind.
