IGI certified lab grown diamonds are laboratory-created diamonds that have been examined and graded by the International Gemological Institute. The certification confirms that the stone is a lab grown diamond and records key quality factors such as carat weight, color, clarity, cut, and measurements. For buyers, the report is mainly a verification tool that helps compare stones using documented grading rather than seller claims alone.
What an IGI certificate means for a lab grown diamond
An IGI certificate is an independent grading report issued after gemological testing. For a lab grown diamond, the report identifies the stone as laboratory grown and documents measurable characteristics used to compare quality across diamonds.
This matters because lab grown diamonds are real diamonds, but the value of any individual stone still depends on its grading details. On La Maison Val D'or, several loose stones and finished pieces are explicitly listed with IGI certification, including an 8ct IGI certified lab grown diamond and a 2ct IGI certified cushion lab diamond, both described with color and clarity grades that make side-by-side comparison easier.
What information appears on an IGI lab grown diamond report
An IGI lab grown diamond report usually includes the stone's shape, measurements, carat weight, color grade, clarity grade, and cut information where applicable. It may also include growth method references such as CVD or HPHT, along with a report number and inscription details if the stone is laser inscribed.
Those details help answer practical questions: whether the diamond matches the listing, whether the stated quality is documented, and whether the stone is suitable for a ring, pendant, or custom project. For example, La Maison Val D'or lists a 2.03ct IGI lab diamond CrissCut with E color, VS1 clarity, and excellent cut, and a trillion cut IGI lab diamond with E color and VVS2 clarity, which reflects the kind of report-backed specs buyers use for comparison.
How IGI certified lab grown diamonds differ from uncertified stones
The main difference is documentation. A certified stone has an independent grading record, while an uncertified stone relies primarily on the seller's own description.
That does not automatically make every uncertified diamond poor quality, but it does make comparison harder. When a listing states exact grades and ties them to IGI certification, as seen in pieces like the 10ct radiant lab diamond ring and the 10 carat pear lab diamond ring, the buyer has a clearer basis for evaluating the center stone.
What IGI certification does and does not guarantee
IGI certification verifies grading information and identifies the diamond as lab grown based on gemological testing. It is a quality report, not a price guarantee, and it does not mean every certified diamond has the same market value.
Value still depends on the full combination of carat size, cut quality, color, clarity, shape, and jewelry setting. For finished jewelry, certification usually applies to the center stone or the specifically listed stones rather than every accent stone unless the listing says otherwise. This distinction is visible in catalog examples such as the IGI lab diamond tennis choker, where the listing explicitly notes IGI certified lab grown diamonds and approximate total carat weight.
How to read an IGI certified lab grown diamond when comparing options
Start with the basics: confirm the stone is identified as laboratory grown, then compare shape, carat weight, color, clarity, and cut. After that, check measurements because two diamonds with the same carat weight can face up differently depending on proportions and shape.
For jewelry buyers, the next step is matching the report details to the intended use. A loose stone can be better for custom projects, while a finished ring or necklace can be the better fit if the report-backed center stone is already set in the style you want. La Maison Val D'or offers both routes, from loose certified stones to set pieces such as the 10 ct IGI lab diamond ring.
Are IGI certified lab grown diamonds real diamonds?
Yes. A lab grown diamond is still diamond, with the same core chemical and physical identity as a mined diamond. The difference is origin: one is grown in a laboratory, and the other forms naturally in the earth.
That distinction appears repeatedly in La Maison Val D'or product descriptions for certified lab grown diamond jewelry and loose stones, which describe lab grown diamonds as having the same core diamond composition or the same physical and optical properties as mined diamonds.
