How to choose your Lab Grown Diamond
Choosing a lab-grown diamond means understanding what makes a diamond sparkle, last, and retain value. At DDL, we only work with diamonds that are H color or better, with a minimum VS2 clarity and Very Good cut, so that any selection you make in our search tool is already above the usual market standard.
Define your budget before choosing
Lab-grown diamonds can be up to 80% cheaper than mined diamonds with the same chemical composition and optical properties. Before filtering by carat or cut, decide what budget you want to allocate to the diamond: it will help you balance size, quality, and certification without sacrificing any important criteria.
The 4Cs: cut, color, clarity, and carat
The 4Cs are the universal language used to describe a diamond. Every GIA or IGI certificate includes them, and we use them to filter our search results.
Cut: The key to brilliance
The cut determines how the diamond reflects light: brilliance, fire, and scintillation. At DDL, we work with Very Good, Excellent, or Ideal cuts, because a poor cut dulls even a diamond with good color and clarity.
Clarity: Clarity without visible inclusions
Clarity measures internal inclusions. Our minimum is VS2: inclusions exist but are not visible to the naked eye, either mounted or in hand.
Color: From Colorless to Slightly Warm
The color scale ranges from D (completely colorless) to Z. At DDL, the minimum is H, within the near-colorless range, where the eye does not perceive a yellowish tint in a finished piece of jewelry.
Carats: Weight and Visual Size
Carat is a measure of weight, not size. Two diamonds of the same weight may appear different depending on their cut and proportions. Therefore, it's better to seek a balance between carat weight and cut than to pursue a specific number.
Gemological advice before buying your diamond
If you are hesitating between two diamonds, are unsure about the 4Cs, or need a diamond for a B2B project, write to us. Our team will review GIA or IGI certificates with you, suggest options within your budget, and guide you until the diamond is in your hand.
GIA or IGI Certification: what each diamond includes
Each DDL diamond comes with its original certificate issued by GIA or IGI, the two leading gemological laboratories. The certificate documents the 4Cs, exact measurements, symmetry, polish, and fluorescence, and includes a unique laser-engraved number on the diamond's girdle. You can view the certificate's PDF on the product page before purchasing it.

FAQs about buying lab grown diamonds
Yes. A lab-grown diamond has the same chemical composition (crystallized carbon), the same atomic structure, and the same optical and hardness properties as a mined diamond. The only difference is its origin: it is created in a controlled environment instead of being extracted from underground.
Every diamond we sell at DDL includes its original GIA or IGI certificate. You can view the certificate PDF directly on the diamond's product page before purchasing it, and verify the laser-inscribed number on the girdle with a 10x loupe, which is commonly used in jewelry.
The production chain is shorter: there is no mining extraction or traditional intermediaries. This allows us to offer lab-grown diamonds that are up to 80% more affordable for the same 4Cs and certification
