A Few Ways To Make Your Engagement Ring Look Bigger

We all know that diamond engagement rings are a symbol of love and commitment. But beyond sentiment, the visual impact of your ring matters — and you don't need to spend a fortune to make it look stunning. At MOH London's Hatton Garden atelier, we help couples every day select rings that look far more impressive than their carat weight might suggest. Here are our expert tips for maximising the visual presence of your engagement ring.

Find the Best Diamond Cut

When shopping for an engagement ring, the cut of the diamond is just as important as the carat weight — arguably more so. The cut determines how brilliantly the stone reflects light, and a well-cut diamond will appear noticeably larger and more radiant than a poorly cut stone of the same size.

Explore Diamond Shapes

The best cuts for maximising visual size include round brilliant, princess, and marquise. A round brilliant diamond with an excellent cut grade can appear up to 15% larger than an equivalent stone with a fair cut grade. At our Hatton Garden showroom, our diamond experts can show you the dramatic difference side by side.

If you're working with a defined budget, prioritising cut quality over carat weight is one of the smartest decisions you can make. A 0.90ct diamond with an excellent cut will often look larger and more impressive than a 1.00ct diamond with a good cut. Use our Diamond Size Chart to visualise how different carat weights appear on the finger.

Be Decisive About Diamond Shape

The shape of your diamond significantly affects how large it appears on the finger. Elongated shapes — such as oval, marquise, and pear — have a larger surface area relative to their carat weight, making them appear bigger than round diamonds of the same weight.

An oval diamond, for example, can appear up to 10% larger than a round diamond of the same carat weight. This is one reason oval has become the fastest-growing shape choice among couples visiting our Hatton Garden showroom.

Consider your finger shape when choosing: if you have slender fingers, elongated shapes will complement them beautifully. If you prefer a more classic look, a round brilliant remains the most popular choice for good reason — its unmatched sparkle draws the eye and creates presence.

White Metal Makes Your Diamond Look Bigger

The metal you choose for your ring band directly affects how large your diamond appears. White metals — platinum and 18K white gold — reflect light rather than absorbing it, creating a seamless visual line between the band and the stone. This makes the diamond appear to extend further than it actually does.

Platinum is particularly effective for this purpose. Its naturally white colour won't yellow over time, ensuring your diamond always looks its brightest. At MOH London, platinum is our most recommended metal for solitaire engagement rings where you want the diamond to take centre stage.

That said, yellow gold and rose gold have their own charm and are increasingly popular for vintage-inspired designs. If you prefer a warm metal, consider a white gold or platinum prong setting on a yellow gold band — the best of both worlds.

Understanding Settings That Make Your Diamond Look Bigger

The right setting can make a remarkable difference in how large your diamond appears. Here are the most effective options:

• Halo setting: A circle of smaller diamonds surrounding the centre stone can make it appear 30-50% larger. This is one of our most popular styles at the Hatton Garden showroom.

• Bezel setting: A thin band of metal encircling the diamond can make it appear up to 12% larger while also protecting the stone's edges.

• Tension setting: Suspending the diamond between two pieces of metal creates the illusion of a floating stone, making it appear up to 20% larger.

• Pavé band: Small diamonds set along the band draw the eye towards the centre stone and add overall sparkle, making the entire ring appear more substantial.

Our Hatton Garden team can walk you through each setting style in person, showing you how the same diamond looks in different configurations. Browse our full Engagement Ring Guide for more details.

Consider a Lab-Grown Diamond

If you want a larger diamond without stretching your budget, lab-grown diamonds offer a compelling solution. These diamonds are chemically, physically, and optically identical to natural diamonds — the only difference is their origin.

Lab-grown diamonds are typically 30-40% less expensive than natural diamonds of equivalent quality. This means the budget that would buy a 0.70ct natural diamond could secure a 1.00ct or larger lab-grown stone of the same quality.

At MOH London, we offer both natural (GIA certified) and lab-grown (IGI certified) diamonds. You can compare them side by side at our Hatton Garden showroom — most people cannot tell the difference without specialist equipment.

Keep Your Diamond Ring Clean

A clean diamond reflects light far more effectively than a dirty one, appearing brighter and larger. Over time, everyday oils, lotions, and soap residue build up on the stone's surface, dulling its sparkle.

We recommend cleaning your engagement ring every 2-3 months at home:

• Soak in warm water with a drop of mild dishwashing soap for 20 minutes

• Gently brush with a soft toothbrush, paying attention to the underside of the stone

• Rinse under warm running water

• Pat dry with a lint-free cloth

Final Thoughts

Making your engagement ring look bigger isn't about deception — it's about smart choices that maximise the beauty of your diamond. By prioritising cut quality, choosing an elongated shape, selecting a white metal, and picking the right setting, you can create a ring that looks far more impressive than its carat weight alone would suggest.
