The science behind the stone

Lab-grown diamonds. Everything you need to know.

Real diamonds, grown above ground. From CVD and HPHT science to IGI certification, durability, and custom timelines — get clear answers before you choose your stone.

Questions, answered

Lab-grown diamonds are real diamonds created in a controlled laboratory environment. They share the same chemical composition, crystal structure, optical properties, and physical hardness as mined diamonds — pure crystallised carbon. The only difference is origin: one forms underground over billions of years, the other is grown above ground in weeks using advanced technology.
CVD (Chemical Vapour Deposition) grows a diamond from a carbon-rich gas plasma layered onto a diamond seed. HPHT (High Pressure High Temperature) replicates the Earth's conditions by applying extreme heat and pressure to a diamond seed. Both produce gem-quality diamonds; CVD tends to excel in larger, high-clarity crystals, while HPHT can yield excellent colour grades. At DIAMO ELITE, every stone is selected for cut, colour, and clarity regardless of growth method.
A one-carat lab-grown diamond typically takes 2–4 weeks to grow, followed by cutting, polishing, and grading. Larger or bespoke stones above 3 carats may require additional growth cycles and can take 6–12 weeks from seed to finished gem. Made-to-order stones above 10 carats are grown individually and quoted with a dedicated production timeline.
Lab-grown diamonds are real diamonds — not simulants. They are chemically, optically, and physically identical to mined diamonds and test positive on any diamond tester. Simulants such as moissanite (silicon carbide) and cubic zirconia (zirconium dioxide) only look similar to the eye but have different hardness, refractive index, and chemical makeup.
Yes. Every DIAMO ELITE lab-grown diamond is graded and certified by IGI (International Gemological Institute). The report confirms carat weight, colour, clarity, cut grade, and — crucially — that the stone is laboratory-grown. This gives you the same independent assurance as a mined-diamond certificate.
Absolutely. Lab-grown diamonds score 10 on the Mohs hardness scale, the same as mined diamonds. They resist scratching, withstand daily wear, and retain their brilliance indefinitely. You can set them in engagement rings, wedding bands, and heirloom pieces with complete confidence.
To the naked eye, there is no visible difference. Even trained gemmologists cannot distinguish them without specialised equipment. The laser inscription on the girdle and the accompanying IGI certificate disclose the stone's lab-grown origin — not because it looks different, but because transparency matters.
Lab-grown diamonds typically cost less than mined diamonds of equivalent quality, allowing you to choose a larger or higher-grade stone for the same budget. Like most consumer purchases, resale value is not guaranteed and is generally lower than the original purchase price. We recommend buying a lab-grown diamond for its beauty and ethics, not as a financial investment.
Lab-grown diamonds eliminate mining, which avoids land displacement, habitat disruption, and conflict-financing risks. They are grown in traceable facilities with a significantly smaller land and water footprint. At DIAMO ELITE, we partner with IGI-audited growers so every stone has a documented, responsible origin.
DIAMO ELITE focuses on the top of the grading scale: colourless D–F grades and VS1 clarity or better, with Excellent cut. This is the range that reads bright white and eye-clean without paying for improvements no one can see. Fancy colours such as pink, blue, and yellow are also available by request.
Yes. Our made-to-order service lets you request specific carat weights, shapes, colours, and clarities. Stones above 10 carats or rare fancy colours are grown to order and quoted individually with a dedicated lead time and production notes.
Yes. Lab-grown diamonds can be set in exactly the same way as mined diamonds — solitaires, halos, three-stone rings, earrings, pendants, and bespoke designs. Our team can advise on the best cut and proportions for your chosen setting.
