There’s a new front-runner in the engagement world — and it’s timeless, elegant, and unmistakably romantic. The oval engagement ring is leading 2025’s top trends, thanks to its flattering shape, vintage-meets-modern appeal, and growing celebrity fan base. With high-profile proposals flooding social media and red carpets alike, it’s clear that the oval cut is having a major moment.
But it’s not just about the shape — it’s what the stone stands for. Let’s dive in!
Why Oval Engagement Rings Are Taking Over in 2025
In a world full of fleeting trends and fast fashion, natural diamonds continue to hold their ground as the most meaningful choice for couples and celebrities alike. Their allure isn’t just about sparkle — it’s about history. Formed over billions of years beneath the Earth’s surface, each natural diamond is completely unique — a rare, one-of-a-kind creation that speaks to the uniqueness of your love story.
Celebrities are choosing natural oval diamonds for their beauty and authenticity — a true statement of lasting commitment. At Bell & Brunt Jewellers in Adelaide, we honour that same sentiment by handcrafting custom oval engagement rings from ethically sourced, natural diamonds. Our pieces aren’t just jewellery — they’re heirlooms in the making.
Celebrities Who Chose Oval Natural Diamonds
Winnie Harlow’s Glamorous Oval Engagement Ring
When Winnie Harlow revealed her jaw-dropping 8.5-carat oval diamond ring, the jewellery world took notice. Set with pear-shaped side stones, her ring is the perfect blend of modern elegance and classic sophistication. This three-stone design has long symbolised the past, present, and future — making it a romantic choice with layered meaning. The look also elongates the finger beautifully, perfect for those who love both style and symbolism.
Simu Liu & Allison Hsu’s Classic Oval Solitaire
Actor Simu Liu made headlines with his timeless proposal: an estimated 6-carat oval solitaire diamond in a simple setting that put all the sparkle on centre stage. This oval engagement ring proves that oval cuts are elegant without needing extra embellishment. It’s a modern minimalist’s dream — clean lines, flawless proportions, and no distractions. For couples wanting their diamond to do all the talking, this is the ultimate inspiration.
Whether you’re drawn to a minimalist oval solitaire engagement ring, a glamorous platinum three-stone look, or a warm gold oval engagement ring, there’s never been a better time to create something truly personal, truly beautiful — and truly yours.

Key Oval Design Trends Inspired by Celebrities:
1. Hidden Halo Settings
What’s better than a halo of diamonds? One you can’t see until you take a closer look. Hidden halo settings tuck a sparkling ring of small diamonds underneath the main oval stone, adding a subtle boost of brilliance from all angles. This design creates a ‘floating’ effect that makes the centre diamond appear larger and more elevated. It’s a favourite among those who want something unique, refined, and just a little bit special — like a love story told in whispers, not shouts. Bonus: it’s ideal for brides who want extra sparkle without going over-the-top.

2. Side Stones & Three-Stone Styles
Whether you’re inspired by Winnie Harlow or vintage royal designs, side stones are a creative way to personalise your engagement ring. Adding pear, baguette, marquise, or trillion-cut accents brings balance, contrast, and often, historical flair. At Bell & Brunt, we work with you to custom-design a piece that’s meaningful — perhaps incorporating heirloom diamonds from your family or choosing a gemstone that represents your story. It’s not just a ring; it’s your past, present, and future in precious form.

3. Minimalist Solitaire Rings
The oval solitaire has gone from understated to iconic. With a single, beautifully cut oval stone set on a slim band, this look allows the diamond’s natural fire and brilliance to shine without distraction. It’s a popular pick for couples who value craftsmanship and clean design. Simu Liu’s fiancée helped bring this trend into the spotlight, but it’s truly timeless — especially when made by hand and tailored to your lifestyle and taste. Custom solitaire diamond rings also give you the freedom to explore band textures (brushed, high polish, matte), stone orientation (horizontal or vertical), and setting heights for that just right balance.
Love the less-is-more look?
4. Yellow Gold Is Back
Yellow gold is having its revival moment — and for good reason. Its rich, warm tone beautifully complements the white sparkle of an oval diamond, giving your ring a hint of vintage romance. It’s also the most malleable of precious metals, making it perfect for hand engraving or custom flourishes. Yellow gold works particularly well with both classic solitaires and bold, vintage-inspired designs. And if you’re not quite sure it suits your skin tone, our team at Bell & Brunt can show you side-by-side comparisons with rose gold and white gold oval engagement rings to find your perfect match.
Crushing on that golden glow?
Why Choose Natural Diamonds Over Lab-Grown
Enduring Value, Rarity & Heritage
A natural diamond is more than just a stone — it’s a geological wonder, billions of years old. That’s part of what gives it its intrinsic value. Unlike lab-grown diamonds, natural diamonds are finite and rare, which adds to their desirability and makes them a wise long-term investment.
They also carry emotional and historical weight. Choosing a natural diamond means you’re wearing a piece of the Earth’s history — and creating your own. Many couples select natural diamonds to build a legacy, passing down their engagement ring to future generations. Celebrities and royals alike continue to choose natural over lab-grown because of this sense of permanence, prestige, and meaning.
At Bell & Brunt, we only source certified natural diamonds, carefully selected for quality, brilliance, and ethical integrity. When we create a custom piece for you, you’re not just buying a ring — you’re investing in a story that lasts forever.
Still deciding between natural and lab-grown?
How to Get the Celebrity Look
Want to recreate the luxe looks without the Hollywood budget? We’ve got you. Here’s how we help you bring the red carpet sparkle to real-life romance:
Pick the Right Carat Size for You
From a dazzling 2 carat oval diamond ring to a daintier, elegant 1.2ct solitaire, there’s a perfect size for every style and budget. The best part? Oval diamonds naturally appear larger per carat than round or square cuts thanks to their elongated shape — so you can get maximum finger coverage without going up in cost. We’ll guide you through carat weights, proportions, and even creative alternatives like diamond clusters or halos to maximise sparkle for your spend.
Book a one-on-one consultation and let us guide you through your options with real diamonds in hand.
Choose Your Metal & Setting
The setting and metal colour can completely change the personality of your ring. Love warm tones? Try a yellow gold oval engagement ring for timeless romance. Prefer a modern edge? Go for white gold or platinum for a sleek, clean finish. Feeling a little bold? Rose gold adds a fresh, feminine twist. We’ll also show you popular setting options — like a classic solitaire, a three-stone arrangement, or a trending East–West setting (where the oval lies horizontally across the finger – very chic!). Every detail is customisable, so you’ll walk away with a ring that feels like you.
