Real diamonds, sustainably made

Diamonds with a purpose

The Making of a Diamond

Lab-grown diamonds are made using cutting-edge technology that recreates the conditions that form diamonds in nature.

Mined diamonds are created deep under the Earth’s surface, where the high pressure and temperature conditions crystalize carbon to create a diamond. Lab-grown diamonds can be made using the HPHT or CVD methods, which use different processes to subject a diamond seed to intense pressure, extreme heat and carbon over a period of several weeks. The result is a genuine diamond with chemical, physical and optical characteristics identical to a mined diamond.

Lab-grown diamonds are an ethical and sustainable alternative to mined diamonds, and it’s impossible to tell the two apart. They are cut and polished just like mined diamonds, and each one has unique characteristics. Like all diamonds, their quality can be measured by the 4Cs — cut, color, clarity and carat.

Why Choose Lab-Grown Diamonds?

100% Conflict-free

There’s no human cost to owning lab-grown diamonds. They’re grown in a lab using technology, so you can be sure your diamond has been ethically sourced, without conflict and human exploitation.

Minimize Impact on Nature

Creating diamonds in a lab reduces damage to the Earth as it doesn’t erode soil or pollute water. By buying a lab-grown diamond, you’re supporting a movement that preserves natural habitats and keeps communities together.

Attractive Pricing

From diamond seed to set in jewelry, a lab-grown diamond’s journey involves fewer steps. The shorter supply chain means you can get a larger lab-grown diamond that suits your style and budget.

Diamond Simulants

Lab-grown diamonds are real diamonds. They’re physically, chemically and optically identical to mined diamonds, with the same sparkle and brilliance. The only differentiating factors are their origin and sustainability.

Diamond simulants—cubic zirconia, moissanite, white topaz or even glass—aren’t diamonds at all. They don’t share the very things that define mined and lab-grown diamonds—their chemical composition and physical structure. They also lack luminescence, and can be easily differentiated from mined and lab grown diamonds.
