Why Old Mine Cut Diamonds Are Back in Vogue

In a world where modern technology has made diamond cutting more precise than ever, there has been a surprising revival of one of the oldest styles in diamond history – the old mine cut. Once considered outdated compared to today’s brilliant cuts, these antique gems are now finding favour among collectors, jewellery designers, and couples searching for something truly unique.

A Glimpse into History

The old mine cut originated in the 18th and 19th centuries, long before advanced cutting technology existed. Cut by hand, often by candlelight, each stone carries its own distinctive character. With their cushion-like shapes, high crowns, and larger culets, old mine cuts reflect the craftsmanship of a bygone era. These diamonds were the predecessor to today’s modern round brilliant and are often set in antique or Victorian-era jewellery.

The Allure of Imperfection

Unlike modern cuts that maximise sparkle through precision, old mine cut diamonds are celebrated for their individuality. Their facets were designed for softer, romantic light sources like candlelight, giving them a warmer, more subtle glow. For many buyers, this charm lies in their imperfections – no two are exactly alike.

Sustainability and Authenticity

As sustainability becomes increasingly important in jewellery, old mine cut diamonds are seen as an eco-conscious choice. They are recycled treasures, requiring no new mining, which makes them especially appealing to ethically minded consumers. Owning one also means owning a tangible piece of history – a connection to a time when diamonds were cut entirely by hand.

Modern Designers Embrace the Vintage Appeal

Jewellery houses and bespoke designers are incorporating old mine cut diamonds into contemporary settings, blending antique beauty with modern design. Their romantic look pairs well with minimalist mountings, allowing the character of the stone to shine through. Many brides-to-be are also choosing them for engagement rings, preferring their vintage charm over mass-produced, uniform cuts.

A Market on the Rise

With limited supply and growing demand, old mine cut diamonds are becoming more sought after. Collectors appreciate their rarity, while younger generations value their individuality and authenticity. This resurgence has pushed prices higher, making them not just a sentimental choice, but also a potentially wise investment.

The revival of old mine cut diamonds reflects a broader trend in the jewellery world: a desire for uniqueness, sustainability, and authenticity. Far from being a relic of the past, these antique diamonds are back in vogue – and for many, they represent the perfect blend of history and timeless beauty.

Will Taylor Swift’s Engagement Ring Spark a Revival of Old Mine Cut Diamonds?

Taylor Swift and Travis Kelce’s engagement has captured global attention but it’s the diamond on Swift’s finger that has the jewellery world talking. The ring, created by Kindred Lubeck of Artifex Fine Jewelry, showcases what appears to be an old mine cut diamond, set in a delicate yellow gold bezel band. Its vintage charm, impressive size, and famous wearer have already made it one of the most talked-about engagement rings of the year.

What Makes Old Mine Cut Diamonds Special?

Old mine cuts are antique diamonds, hand-cut in the 18th and 19th centuries, before modern technology standardised proportions. Each one is truly unique, known for:

Chunky facets that give off a soft, romantic sparkle.

A high crown and small table, creating depth and character.

An open culet, a tiny facet at the bottom that adds to its antique charm.

Unlike today’s round brilliants, no two old mine cuts are ever the same—making them a perfect choice for those who want something one-of-a-kind.

The Value of Swift’s Diamond

Experts estimate Taylor’s diamond to be between 8 and 15 carats, with valuations ranging anywhere from USD $400,000 to over $1 million depending on its exact specifications. While few engagement ring budgets stretch quite that far, her choice highlights a rising trend: a return to antique and vintage stones.

Why Are Couples Choosing Antique Cuts?

In recent years, there’s been a growing interest in diamonds with personality and heritage. With the rise of lab-grown diamonds offering affordability and size, many buyers are instead turning to antique stones for uniqueness and history. As one jeweller put it: “Antique stones offer character you simply can’t replicate.”

A Timeless Trend

Taylor Swift’s engagement ring has brought the old mine cut back into the spotlight, and for many couples, it’s a reminder that engagement rings don’t have to follow the latest modern style. Choosing an antique cut is about more than sparkle—it’s about individuality, history, and wearing a diamond with a story.
