Explore Engagement Rings by Style and Design

There is no single style that makes the perfect engagement ring. Some designs keep the focus on one beautiful centre stone, while others add extra diamonds for more sparkle or use distinctive details to create a more personal look. Our collection of lab grown diamond engagement rings includes a variety of styles to suit different tastes and lifestyles, helping you explore the types of engagement rings that best match the look, personality and everyday needs of the wearer.

Understanding what makes each design different can help you choose a ring that feels right and stays beautiful for years to come.

Solitaire Engagement Rings

Solitaire engagement rings feature a single centre diamond held as the focal point, creating a clean and timeless look. They are ideal for someone who prefers understated elegance and a design that remains versatile for everyday wear. With fewer surrounding stones competing for attention, the centre diamond’s cut, shape and brilliance become especially important.

Hidden Halo Engagement Rings

Hidden halo engagement rings add a circle of smaller diamonds beneath the centre stone, creating extra sparkle that is visible from the side without changing the clean look from above. This is a thoughtful choice if you want the ring to feel classic at first glance while adding a subtle detail and greater visual presence.

Halo Engagement Rings

Halo engagement rings surround the centre diamond with smaller stones, creating a fuller appearance and enhancing its overall sparkle. They suit those who love a glamorous, eye-catching design and can make the centre stone appear more prominent within the setting.

Three Stone Engagement Rings

Three stone engagement rings feature three diamonds that are often associated with the past, present and future of a relationship. The balanced three-stone layout gives the ring meaningful symbolism while adding more brilliance than a traditional solitaire, making it a strong choice for couples who want their engagement ring design to tell a story.

Toi Et Moi Engagement Rings

Toi Et Moi engagement rings bring two diamonds together in one design, symbolising two individuals becoming one. Their distinctive two-stone silhouette feels romantic and contemporary, making them an appealing choice for someone looking beyond traditional diamond engagement ring designs.

Vintage Inspired Engagement Rings

Vintage inspired engagement rings draw attention through intricate details such as milgrain edges, delicate engraving, floral motifs and ornate settings. Their distinctive craftsmanship gives them a romantic, heirloom-inspired character, making them ideal for someone who prefers a ring with old-world charm and plenty of personality.

Modern and Minimalist Engagement Rings

Modern and minimalist engagement rings focus on clean lines, refined proportions and uncomplicated settings. They offer a contemporary aesthetic that works well for everyday wear, especially for someone who values subtle sophistication over elaborate detailing. For those exploring modern diamond engagement ring designs, these styles let the centre stone take focus without making the ring feel overly ornate.

Popular Diamond Shapes for Engagement Rings

The diamond shape sets the overall look of an engagement ring, from the classic sparkle of a round cut to the elegant, elongated profile of an oval or marquise. Your choice often comes down to the style you love, how the diamond looks on the finger and the kind of presence you want from the centre stone. ONYA’s lab diamond engagement rings are available in a range of popular shapes, making it easier to find one that feels right for you.

Round Cut Engagement Rings

Round cut engagement rings are a timeless choice, especially if you love maximum sparkle. The round brilliant cut is designed to reflect plenty of light, giving the diamond exceptional brilliance. Its classic shape also works well with almost any engagement ring design.

Oval Cut Engagement Rings

Oval cut engagement rings offer the sparkle of a round diamond with a longer, more elegant shape. The elongated outline can make the diamond appear larger and create a graceful look on the finger. Choose an oval if you want something classic with a little more character.

Emerald Cut Engagement Rings

Emerald cut engagement rings have long, clean facets that give the diamond a smooth, elegant appearance rather than intense sparkle. This shape puts more focus on the diamond’s clarity and proportions, making it a great choice for someone who prefers understated sophistication.

Cushion Cut Engagement Rings

Cushion cut engagement rings have soft, rounded corners and a gently squared shape that gives them a romantic, timeless appeal. Their broad facets create beautiful sparkle, while the softer outline works well for both classic and modern engagement ring designs.

Pear Shaped Engagement Rings

Pear shaped engagement rings have a rounded end and a pointed tip, creating their distinctive teardrop shape. The elongated silhouette can make the finger look more slender and gives the ring a graceful, distinctive appearance. It is a lovely choice if you want something elegant but less traditional.

Princess Cut Engagement Rings

Princess cut engagement rings have a sharp square or rectangular shape with faceted edges that create plenty of brilliance. Their clean, geometric look makes them especially suited to modern engagement ring designs and those who prefer a crisp, contemporary aesthetic.

Marquise Cut Engagement Rings

Marquise cut engagement rings have a long, narrow shape with pointed ends that creates a striking and elegant look. Their elongated outline can make the centre diamond appear larger and give the finger a lengthened appearance. It is a distinctive choice for those who want something beyond the usual round or oval.

Radiant Cut Engagement Rings

Radiant cut engagement rings combine a clean square or elongated shape with brilliant faceting for plenty of sparkle. They are a versatile choice if you like the structured look of an emerald cut but want more visible brilliance.

Heart Shaped Engagement Rings

Heart shaped engagement rings feature a distinctive heart-shaped diamond that naturally represents love and romance. Their expressive silhouette makes them a meaningful choice for someone who wants a less conventional design with plenty of personality and sparkle.

Engagement Ring Meaning and Symbolism

An engagement ring symbolises love, commitment and the promise of a future together. Traditionally given during a proposal, it represents the intention to marry and marks the beginning of a new chapter in a couple’s relationship. The diamond itself is often associated with strength, lasting love and enduring commitment, which is why it has become such a meaningful choice for engagement rings.

Why Choose Lab Grown Diamond Engagement Rings?

A lab grown diamond engagement ring gives you more flexibility to choose the diamond and design you genuinely want. Because lab grown diamonds offer greater value within a given budget, you can consider a larger centre stone, higher diamond quality or a more detailed setting while still keeping the ring aligned with what you want to spend. The result is an engagement ring chosen around her style, the diamond’s beauty and your priorities, rather than compromising on the details that matter most.

The same diamond material: Lab grown diamonds are diamonds with the same crystal structure and essential physical and chemical properties as mined diamonds, giving you the beauty and brilliance expected from a diamond.

More choice within your budget: Greater price flexibility allows you to explore different carat sizes, shapes, qualities and designs before deciding what matters most to you.

Confidence in diamond quality: ONYA’s lab grown diamonds are IGI-certified, giving you an independent assessment of the diamond’s characteristics, including its cut, colour and clarity.

Made for a lifetime of wear: ONYA engagement rings pair carefully selected lab grown diamonds with hallmarked 14K and 18K gold, creating pieces designed to be worn, cherished and remembered long after the proposal.

How to Choose the Perfect Engagement Ring

Choosing the perfect engagement ring can feel overwhelming when you have so many designs, diamond shapes, carat sizes and gold options to consider. The easiest way to narrow it down is to start with her personal style, then look at the diamond, setting, metal and comfort to find a ring that feels beautiful and right for everyday wear.

A meaningful engagement ring does not have to be the biggest or most expensive one. The right choice is a ring that reflects her personality, fits comfortably, suits her lifestyle and gives you the balance of beauty and value you are looking for. With lab grown diamond engagement rings, you also have more flexibility to explore different designs and diamond specifications within your budget.

Start With Her Personal Style

Look at the jewellery she already wears for clues. Delicate pieces may suit a solitaire or minimalist design, while someone who loves sparkle may prefer a halo, three-stone or detailed setting. If the proposal is a surprise, pay attention to her usual gold colour, jewellery style and level of detailing.

Choose a Diamond Shape That Matches Her Style

The diamond shape affects how an engagement ring looks on the finger. Consider both her hand shape and personal style:

• Shorter or wider fingers: Oval, pear and marquise shapes can create a longer, more slender appearance.
• Longer fingers: Round, cushion and princess cuts offer a balanced, proportionate look.
• Slim fingers: Most diamond shapes work well, so personal preference can take priority.
• For a classic look: Choose round or oval.
• For understated elegance: Consider emerald.
• For a distinctive look: Pear or marquise can add a more elongated, graceful appearance.

Find the Right Carat Size and Proportion

Carat is the diamond’s weight, but the right size depends on how it looks on the hand, the diamond shape and the overall ring design.

Under 0.50 carat: Subtle and delicate, ideal for a minimalist look.

0.50 – 1 carat: A balanced choice for everyday wear, offering good presence without feeling overwhelming.

1 – 2 carats: More noticeable and suited to those who want a larger centre diamond.

Above 2 carats: Best for a statement look with greater visual presence.

With lab grown diamond engagement rings, you can explore larger carat sizes while still balancing cut, colour, clarity and budget.

Choose the Right Engagement Ring Setting

The setting affects the ring’s appearance, security and everyday wearability.

Prong setting: Keeps the diamond visible from different angles and allows plenty of light to enter.

Halo setting: Surrounds the centre diamond with smaller stones for extra sparkle and a fuller appearance.

Bezel setting: Encloses the diamond with metal, offering added protection and a clean, modern look.

Pavé setting: Uses small diamonds along the band to add continuous sparkle.

Choose Your Gold Karat and Colour

The gold you choose changes the overall look of the engagement ring, while the karat affects its gold content and durability.

• Yellow gold: Warm, classic and timeless.
• White gold: Bright, modern and versatile.
• Rose gold: Soft, romantic and distinctive.
• 14K gold: A practical balance of durability and gold content for everyday wear.
• 18K gold: Higher gold content with a richer, more luxurious finish.

For an engagement ring worn every day, choose the gold colour she prefers and a karat that fits her lifestyle and desired finish.

In Which Finger to Wear an Engagement Ring?

The engagement ring finger for men and women is traditionally the ring finger, although the hand can vary by culture and personal preference. In India, some couples wear engagement rings on the right hand, while others choose the left. After marriage, the wedding ring or wedding band is also commonly worn on the ring finger, with couples choosing whether to wear the engagement ring and wedding ring together or separately. Ultimately, the right finger for an engagement ring is the one that feels comfortable and meaningful to you, whether you are choosing an engagement ring for a woman or a man.
