Choosing an engagement ring is a moment unlike any other, and having the right knowledge makes all the difference.
This guide walks you through the essentials - diamond cuts and settings, precious metals, the 4Cs, sizing, and more - so you can feel informed and confident in your decision.
The setting is one of the most important parts of an engagement ring. It affects how the diamond looks, how much it sparkles, and how practical the ring is for everyday wear.
Each style offers a different balance of simplicity, detail, and presence on the hand.
Fraser Hart Tip
Consider both style and practicality.
For someone who uses their hands often or prefers a low-maintenance style, a solitaire or three-stone ring offers practicality without compromising on elegance.
Cluster or halo designs bring more sparkle, but they may need a bit more care and attention to keep them looking their best.
Cut and shape are often confused — but they play very different roles.
Shape is the outline of the diamond (like round, oval, or emerald), while cut is all about how well it reflects light.
Fraser Hart Tip
Cut and shape are often confused but mean very different things. Shape is the outline of the diamond - such as round, oval, or emerald.
Cut refers to how well the stone’s proportions and facets reflect light, which is what creates brilliance and sparkle. Both play an important role in how a ring looks and feels.
The metal you choose affects both the look and the durability of the ring. Some metals are bright and modern, others warm and traditional, and each has its own practical considerations for everyday wear.
Fraser Hart Tip
Look at the jewellery your partner already wears. Do they lean towards silver tones or warmer shades?
Choosing a metal that matches their style will make the ring feel even more personal.
Both lab-grown and mined diamonds are real diamonds - chemically and visually identical. The only difference is where they come from.
Lab-grown diamonds are created above ground in controlled conditions. They’re a modern choice with a smaller environmental footprint and are often more affordable, meaning you can choose a larger stone within your budget.
Mined diamonds form naturally over billions of years. Many people value their rarity, heritage, and traditional significance as a symbol of lasting commitment.
There’s no right or wrong choice - it comes down to what feels most meaningful to you.
The 4Cs - cut, colour, clarity and carat - are the global standard for judging diamond quality. Knowing how they work together helps you choose the best balance for your style and budget.
Cut is the most important of the 4Cs. Cut determines how well a diamond reflects light, and therefore how much it sparkles. A well-cut diamond will look bright and lively, even if it’s smaller in size.
Colour refers to how white or colourless a diamond appears. Diamonds are graded from D (colourless) to Z (noticeable yellow tint). Most people choose near-colourless grades like G–I, which still look bright but offer better value than the very top of the scale.
Clarity measures natural inclusions or blemishes inside the diamond. Most are invisible to the eye, so you don’t need a flawless grade. Aim for “eye-clean” diamonds, which look perfect without paying a premium.
Carat refers to weight, not size. Two diamonds of the same carat can look different depending on cut and shape. A larger carat adds presence, but cut and setting play just as big a role in appearance.
There’s no single right combination. Think about what matters most to you: sparkle, size, or value. The best choice is the diamond that feels perfect for your priorities.
Getting the size right can feel daunting, but there are simple ways to make it easier. If your partner already wears a ring on their left-hand ring finger, use that as a reference. You can also visit a Fraser Hart store, where our experts will be happy to measure for the perfect fit.
For at-home help, our Ring Size Guide includes a printable chart, tips for discreet measuring, and advice on keeping the proposal a surprise.
Sometimes choosing the engagement ring itself takes time. A promise ring can be a meaningful way to show commitment while leaving space to choose the final design together later.
Promise rings are available in many styles, from simple diamond bands to more personal designs. They’re ideal if you want to celebrate the proposal now but prefer to pick the forever ring at a later stage.
An engagement ring is more than a piece of jewellery — it’s the beginning of a lifelong story. At Fraser Hart, we’re here to guide you with expert advice, trusted craftsmanship, and a collection that balances timeless classics with modern designs.
