Trending Diamond Shapes in 2025: What’s Hot in Jewellery Design?

When it comes to diamond jewellery, shape is everything. It’s not just about how a diamond sparkles—it’s about the emotion it evokes, how it complements your style, and the story it tells. As we step into 2025, diamond shape trends are evolving beautifully, inspired by fashion movements, personal expression, and a growing awareness around sustainability. With lab-grown diamonds gaining popularity for being eco-conscious and ethically made, more buyers are embracing contemporary design with a conscience. Here’s what’s trending in the world of diamond shapes this year—and how to find the perfect one for you.

Why Diamond Shape Matters

The shape of a diamond influences its brilliance, how light reflects off it, and its overall feel—whether modern, romantic, bold, or classic. Many even believe your chosen shape reflects your personality: think confident and elegant for emerald cuts, or free-spirited and romantic for pear-shaped stones. Choosing the right shape also depends on the occasion—an everyday ring may call for a practical round or radiant cut, while a statement necklace might embrace something more dramatic like a marquise or heart shape.

Top Diamond Shape Trends in 2025

1. Oval Diamonds – Timeless Elegance Continues

Oval diamonds remain a favourite for their flattering, elongated silhouette and vintage-meets-modern vibe. Seen on countless celebrity lab grown diamond engagement rings, their brilliant sparkle works beautifully in solitaire or halo settings.

2. Emerald-Cut Diamonds – Clean Lines & Quiet Luxury

Step-cut diamonds are very popular right now, particularly those in emerald and Asscher shapes. Emerald cuts, which are adored for their subtle elegance, go well with minimalists who appreciate clarity and a long, streamlined profile.

3. Pear-Shaped Diamonds – Bold & Feminine

With their teardrop design, pear-shaped diamonds add a unique twist to any piece. Ideal for rings, pendants, or statement earrings, they feel romantic yet contemporary. Look for protective settings to keep the pointed tip secure.

4. Radiant-Cut Diamonds – Sparkle with Structure

Radiant-cut diamonds, which combine the sparkle of round cuts with the structure of emeralds, are becoming more and more popular, particularly for engagement rings. They are frequently chosen over the conventional princess cut because they provide stunning brilliance with a contemporary twist.

5. Marquise-Cut Diamonds – A Regal Revival

Making a stylish comeback, marquise-cut diamonds are perfect for those who love a vintage feel with a bold twist. Their elongated, pointed shape makes fingers appear longer and adds drama to any piece.

6. Heart-Shaped Diamonds – Romantic & Playful

Heart-shaped diamonds, which were once thought to be out of the ordinary, are now popular because of their striking symbolism. Perfect for promise rings and pendants, they're a great choice for people who enjoy a whimsical yet significant touch.

Sustainable & Ethical Jewellery Trends

2025 is all about mindful luxury. Lab-grown fancy-cut diamonds are now at the forefront of conscious jewellery buying. With no mining involved, they’re a guilt-free choice that doesn't compromise on beauty or brilliance. Brands like Parallel Vault are redefining fine jewellery by combining ethical values with cutting-edge design.

How to Choose the Right Diamond Shape for You

Start by identifying your personality and way of living life: are you bold, enthusiastic, trendy, or classic? Think considering the occasion, how frequently you intend to wear the item, and the shape of your hand. Another factor is the shape's size and appearance, as well as the budget.

Customisation will become vital in 2025. More individuals are selecting designs that feel thoughtful and personal, whether it's a custom necklace or a custom engagement ring.
