Lab-created diamonds go through rigorous certification procedures to ensure their quality and authenticity, similar to naturally mined diamonds. Leading organizations like the Gemological Institute of America (GIA), the International Gemological Institute (IGI), and GCAL are responsible for issuing certifications for lab-created diamonds.

These certificates contain detailed information about the diamond's cut, carat weight, color, clarity, and other important attributes. Each certified diamond is engraved with a unique report number on the girdle to prevent counterfeit, providing assurance of the diamond's identity.

Both natural and lab diamonds display a stunning beauty with equal fire and sparkle, but lab diamonds are more affordable due to the pricey rarity of natural mined diamonds. While the resale value of lab-grown diamonds may be uncertain in the market despite their increasing availability, the value of any diamond, regardless of its origin, is influenced by quality, cut, carat weight, color, clarity, and market factors.

Lab diamonds are authentic diamonds made from pure crystallized carbon, not imitations designed to replicate the look of diamonds. While simulant options like Cubic Zirconia (CZ) and synthetic Moissanite may resemble natural diamonds visually, they do not possess the same physical or chemical characteristics. A knowledgeable jeweler or gemologist can distinguish between Cubic Zirconia, Moissanite, and genuine lab diamonds using a jewelry loupe.
