What is a lab-grown white diamond
A lab-grown white diamond is chemically and physically identical to a natural diamond: pure carbon crystallized in a cubic structure, with the same hardness (10 on the Mohs scale), the same refractive index, and the same brilliance. The difference lies in its origin. Instead of forming thousands of meters deep over millions of years, it is created in a controlled environment in weeks using high-tech processes such as CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature).
The result is a real, certified diamond, visually indistinguishable from a natural one, at a fraction of the price.
Why choose a lab-grown white diamond
The white diamond is the most classic and versatile option. Its transparency and lack of color allow light to enter, refract, and exit as flashes of brilliance. It is the quintessential diamond for engagement rings, solitaires, and high-quality jewelry.
Choosing a lab-grown white diamond adds three clear advantages to that classic beauty: a significantly lower price (more than 80% cheaper than natural diamonds), complete traceability from its creation, and a radically lower environmental impact compared to conventional mining.
How color is evaluated in a white diamond
The color scale for white diamonds ranges from D (perfectly colorless) to Z (visible yellowish tint). The most valued categories are:
D, E, F — Colorless
These are the purest diamonds in terms of color. They show no tint to the naked eye or under a gemological loupe. They are the most sought after in high-end jewelry and receive the highest ratings in IGI and GIA certificates.
G, H, I, J — Near Colorless
They have a tint imperceptible to the naked eye, especially when set in white gold or platinum.
K onwards — Visible Tint
From K onwards, the yellowish tint begins to be perceptible.
The 4Cs applied to the white diamond
Color
In white diamonds, less color means more value. A D-F stone set in platinum or white gold maximizes the mirror effect and brilliance.
Clarity
Clarity indicates the absence of internal or external inclusions. For white diamonds, VS2 (Very Slightly Included) or higher is recommended: inclusions exist but are invisible to the naked eye.
Cut
The cut is the factor that most impacts the brilliance of a white diamond. An Excellent or Ideal cut allows light to enter, refract internally, and exit with maximum fire and scintillation. For white diamonds, the round brilliant cut is the benchmark.
Carat Weight
Carat weight determines visible size. Thanks to their lab-grown origin, it is possible to access high-carat white diamonds —1ct, 2ct, 3ct— at prices that would be prohibitive with natural diamonds.
IGI Certification for lab-grown white diamonds
All white diamonds from Diamante de Laboratorio come certified by the IGI (International Gemological Institute), the global reference laboratory for lab-grown diamonds. The certificate includes the 4Cs, the creation method (CVD or HPHT), the laser-engraved identification number on the girdle, and confirmation of synthetic origin.
The IGI certificate is the guarantee that what you receive is exactly what is described: no surprises, no room for error.
White Lab Grown Diamonds FAQ
Yes. It has the same chemical composition (pure carbon), the same crystalline structure, and the same physical and optical properties as a natural diamond. The only difference is its origin: laboratory instead of mine.
Not with the naked eye or basic instruments. Neither a jeweler nor an untrained person can distinguish them without specific laboratory equipment. What is different is the price and environmental impact.
For engagement rings in white gold or platinum, D-E color grades offer the best combination of sparkle and value. If the setting is yellow or rose gold, grades like F work equally well visually.
The price of lab-grown diamonds has significantly decreased in recent years, as is the case with any product that can be manufactured scalably and with technology. They are pieces of jewelry, not investment assets. Their value lies in the symbolism and quality of the piece, not in speculation.
Both produce high-quality white diamonds. CVD tends to produce stones with purer colors in D-F ranges. HPHT better replicates geological conditions and can offer diamonds with slightly different characteristics. The IGI certificate always specifies the method used.
Yes. At Lab Grown Diamond, we offer the option to select your white diamond and combine it with the setting you prefer: a solitaire in white gold, a pavé in rose gold, or designs in yellow gold. Check our customization options.
