Lab-Grown Diamond Trends for 2026: Larger Stones, New Shapes

Trend 1: Bigger Is the New Normal

It’s no secret: lab-grown diamonds have completely changed the game when it comes to engagement rings. Whereas budgets used to often max out at a 0.7- or 1-carat natural diamond, couples today can get significantly larger stones for the same price.

We’re seeing a clear shift among our female customers. The market average for engagement rings in 2026 is an impressive 1.9 carats. A 2-carat stone is no longer a rarity—for many, it’s the new standard. The best part is that, thanks to lab-grown technology, no one has to break the bank or compromise on quality to get this dream ring.

Trend 2: Bezel Settings & Chunky Gold

For years, the rule of thumb was: the thinner the band, the better. The band was supposed to be virtually invisible so that the diamond would take centre stage. In 2026, this trend will take a complete turn. We’re saying goodbye to extremely delicate 1.5-mm bands and welcoming “chunky gold.”

Wider bands (2 mm and up) not only give the ring a modern, confident look, but are also significantly more durable for everyday wear. In keeping with this trend, the bezel setting is making a huge comeback. Instead of small prongs, a delicate metal rim encircles the entire diamond. This not only looks extremely elegant, but also provides the stone with perfect protection against impacts. A ring made to be worn every day.

Trend 3: Fancy Shapes Instead of Just Round

The classic round brilliant cut will always have its place. But to be honest, in 2026, the spotlight will be on the so-called “fancy shapes.” Leading the way is the oval cut. It makes the finger look longer and, thanks to its larger surface area, appears bigger than a round stone of the same carat weight.

But other shapes are also gaining significant attention. The emerald-green emerald cut, with its clean, architectural lines, is the choice for women who appreciate understated elegance and luxury. Those who prefer a slightly more romantic and softer look might opt for the teardrop-shaped pear cut or the vintage-inspired cushion cut.

Trend 4: The Revival of Yellow Gold

White gold and platinum have dominated the past two decades. But yellow gold is back—and stronger than ever. More than 40% of engagement rings will be made of warm yellow gold in 2026.

The reason is simple: yellow gold flatters almost every skin tone and creates a stunning contrast to brilliant-white (Colour D-F) lab-grown diamonds. The stone often appears even more radiant in a gold setting. In addition, yellow gold pairs perfectly with other everyday jewellery, which is currently also heavily dominated by gold tones.

Conclusion: Have the Courage to Be Yourself

The trends for 2026 show one thing above all else: engagement rings are becoming more personalised. It’s no longer about finding the one “perfect” standard ring, but rather a piece of jewellery that reflects the wearer’s personality. Lab-grown diamonds give us the freedom to get creative without losing sight of our budget.
