Diamonds of The Future

What are lab grown diamonds?

Lab-grown diamonds are real diamonds, created using technology that replicates the natural diamond-growing process deep within the Earth. These diamonds share the exact same physical, chemical, and optical properties as mined diamonds, making them indistinguishable—even to trained gemologists without specialized equipment.

Unlike imitation stones like cubic zirconia or moissanite, lab-grown diamonds are genuine. They sparkle just as brightly, are equally durable, and have the same timeless beauty as mined diamonds.

Just like mined diamonds, lab-grown diamonds are graded by independent gemological laboratories using the same criteria: the Four Cs—cut, color, clarity, and carat weight.

What makes lab-grown diamonds even more extraordinary is their origin. They deliver the luxury and elegance of a mined diamond but are a more ethical and sustainable choice. Free from the environmental and social concerns of traditional mining, lab-grown diamonds are the modern, conscious way to celebrate life’s meaningful moments.

How Are Lab-Grown Diamonds Created?

Lab-grown diamonds are created in controlled laboratory environments using advanced processes that replicate the natural conditions under which diamonds form deep within the Earth’s crust. The result? Stunning, real diamonds that are identical to mined diamonds in beauty, brilliance, and durability.

The best part? This process is ethical and sustainable, avoiding the environmental damage and human impact of traditional mining. With Lumière’s lab-grown diamonds, you get all the sparkle—without the guilt.

Lab-Grown Earth Mined

Purity Fewer impurities and defects due to controlled growing conditions. More likely to contain natural inclusions and imperfections.

What Makes a Diamond 'Real'?

To determine if a diamond is genuine, experts analyze its chemical composition, physical structure, and optical properties. At their essence, diamonds are composed of crystallized carbon atoms, precisely arranged in a cubic lattice structure that gives them unmatched brilliance, strength, and timeless beauty. Lab-grown diamonds meet all the criteria that define a real diamond (just like earth mined diamonds)—they are not substitutes or imitations but authentic gems created using advanced, state-of-the-art technology, identical to earth-mined diamonds in every way.

Myth: Lab-grown diamonds are fake

This is a widespread myth.

Fact: Lab-grown diamonds are 100% real. They are made of carbon atoms arranged in the exact diamond crystal structure—just like mined diamonds. Unlike cubic zirconia or other imitations, lab-grown diamonds are chemically, physically, and optically identical to natural diamonds. When you choose lab-grown, you’re not compromising; you’re upgrading.

Myth: Lab-grown diamonds look different

A common concern is that lab-grown diamonds lack the brilliance of mined diamonds.

Lab-grown diamonds have the same fire, sparkle, and timeless allure as natural diamonds. Their brilliance is indistinguishable even to trained gemologists without specialized equipment.

Fact: Brilliance You Can Feel Good About

When you choose lab-grown diamonds, you’re choosing beauty without compromise. You get all the sparkle and elegance of natural diamonds while supporting a more ethical, sustainable future.
