Frequently Asked Questions

VeraLume™ grading takes the guesswork out of buying a lab-grown diamond. Each diamond is evaluated for both technical precision and face-up beauty, so you know exactly how your diamond performs.

VeraLume™ goes beyond the traditional 4Cs. In addition to Cut, Color, Clarity, and Carat, every diamond is graded for Color Tone, Growth Lines, and Visual Performance—a proprietary score that reflects brilliance, fire, and sparkle. The result is a more complete picture of a diamond’s true quality and appearance.

Unlike IGI and other grading labs that often apply softer color and clarity standards, VeraLume™ uses stricter benchmarks. It also measures visual qualities like sparkle and undertone, giving you a more transparent and accurate assessment of beauty.

Soft grading happens when labs assign inflated color or clarity grades, making diamonds appear better on paper than they look in person. VeraLume™ eliminates this issue by aligning with GIA’s strict standards and adding even more detailed evaluations.

Yes, every VeraLume-certified diamond is also graded by the Gemological Institute of America (GIA). This dual certification gives you the confidence of GIA’s independent verification combined with VeraLume’s advanced reporting.

Each VeraLume™ diamond includes a unique report number. You can enter this number on the VeraLume website to confirm authenticity and view the full digital grading report.

Yes, each diamond is laser-inscribed with its VeraLume report number and corresponding GIA number. These inscriptions ensure your diamond can always be matched to its official grading.

Absolutely! Because every VeraLume™ diamond is backed by a GIA report, insurance companies recognize it for appraisals and coverage. The VeraLume™ report simply adds more transparency and detail.

Color Tone reveals subtle undertones—like brown, gray, or blue—that affect how a diamond looks face-up. Growth Lines are natural patterns from the lab-growing process; only diamonds with minimal or invisible lines pass. Visual Performance is VeraLume’s proprietary measure of sparkle, fire, and overall beauty, showing how radiant a diamond truly appears.

Ideal+ is VeraLume’s top-tier cut standard. It exceeds traditional “Excellent” cut requirements by evaluating polish, symmetry, and proportions with even greater precision to maximize brilliance and light return.

Only about 1 in 10 lab-grown diamonds meet VeraLume’s strict criteria. Diamonds are rejected for issues like uneven undertones, visible growth lines, or lower light performance. This selectivity ensures that only the most visually impressive and well-crafted diamonds earn VeraLume™ certification.

VeraLume™ uses a controlled, repeatable grading process that combines expert gemologist evaluation with advanced imaging and optical analysis. Every diamond is reviewed under the same strict criteria for color, clarity, growth patterns, and light performance, ensuring reliable results across all reports.

Yes, all VeraLume™ diamonds are lab-grown, avoiding the environmental and ethical impact of mining. Each VeraLume has been sourced from responsible producers and certified only after meeting VeraLume’s high standards for transparency and quality.

Lab-grown diamonds significantly reduce environmental impact compared to mined diamonds. They eliminate the need for large-scale excavation and avoid disrupting ecosystems, while offering the same chemical, physical, and visual properties as natural stones. VeraLume™ focuses on grading quality and transparency—ensuring each diamond meets the highest standards of beauty and integrity.
