Lab-grown diamonds are created in a laboratory that recreates the conditions under which diamonds form naturally over millions of years. They are physically, chemically and optically identical to mined diamonds  so identical that even gemologists cannot tell them apart by eye

Yes. A diamond is a diamond because of its chemical composition, not its origin. Lab-grown and natural diamonds share the same crystalline carbon structure, which makes lab-grown diamonds genuine, real diamonds.

Not by looking. Even a trained jeweller cannot distinguish them with the naked eye or a standard microscope. Only specialised equipment in a gemological lab can identify a lab-grown diamond.

Yes. They last forever and hold real value. Diamond Lleaf offers up to 80% buyback on lab-grown diamonds, the same way buyback is offered on natural stones.

Yes. Lab-grown diamonds typically retail at a 60–90% saving over natural diamonds of equivalent quality, and are priced on the same factors  cut, colour, clarity and carat.

Yes. They are graded exactly like mined diamonds. Every lab-grown diamond used by Diamond Lleaf is certified by leading independent labs such as IGI, GIA, SGL or EGL.

No. Cubic zirconia and moissanite are diamond simulants, not diamonds. Lab-grown diamonds are real diamonds with the same composition as natural ones.

Extremely. Diamonds rank 10 on the Mohs scale  the hardest material on earth. Lab-grown diamonds share this rank, so they're strong enough to pass down for generations.

No. They do not fade, discolour or cloud. Their brilliance is permanent.

No. Machines only set the right conditions  nature does the rest. Like mined diamonds, each stone varies in colour, clarity and carat.

Yes. They are characterised on the same four Cs  Cut, Colour, Clarity and Carat.
