In today’s diamond market, few styles have captured as much renewed interest as the old mine cut diamond. Once considered outdated, these antique diamonds are now highly prized for their rarity, individuality, and vintage beauty. For Australians who own one, this revival presents a valuable opportunity.

What Makes Old Mine Cut Diamonds Special?

Old mine cut diamonds date back to the 18th and 19th centuries, long before modern cutting techniques. Recognised by their cushion-shaped outline, high crown, and larger culet, these stones were crafted entirely by hand.

Designed to sparkle in candlelight rather than electric light, they carry a soft, romantic glow that sets them apart from today’s precision-cut diamonds.

This uniqueness – along with their limited supply – is what makes old mine cuts especially sought after today. Collectors and jewellery lovers across Australia are paying a premium for these antique gems, whether as standalone stones or in their original settings.

Why Now is the Time to Sell Old Mine Cut Diamonds

With demand for vintage jewellery climbing, many Australians are discovering that old mine cut diamonds tucked away in heirlooms or antique rings may be worth far more than expected.

The combination of rarity, sustainability, and fashion appeal means these stones are achieving strong prices in the resale market.
