1 Carat Old Cut Lab-Grown Diamond

A 1 carat old cut lab-grown diamond brings the warm, romantic sparkle of antique diamond cutting to a modern, ethically created stone. Unlike the uniform facet pattern of a contemporary round brilliant, old cuts — including Old European and Old Mine styles — have a smaller table, a larger culet, and less mechanically precise faceting, producing a softer, candlelight-like glow rather than sharp modern fire. It's a distinctive choice for vintage-inspired and heirloom-style engagement rings.

Why Choose Lab-Grown Diamonds?

Lab-grown diamonds are real diamonds, produced in high-tech labs that replicate natural geological conditions. They match mined diamonds in chemical composition, physical properties, and optical brilliance — the only difference is how they're formed. Lab-grown diamonds offer excellent value, often costing 30% to 50% less than mined diamonds of the same quality.

At Rêve Diamonds, we offer a wide range of lab-grown diamonds that are certified by leading gemological institutes such as IGI or GIA, ensuring authenticity and quality with every purchase.

What is an old cut diamond?
