Traditional grading evaluates only color, clarity, cut, and carat. VeraLume goes further, analyzing subtle qualities that significantly affect beauty but are often overlooked.
Color Tone
Subtle undertones are carefully identified, even in colorless grades, to ensure accurate evaluation.
Color Tone Scale
Pure: Crisp white, no undertone
Brown: Warm undertone, may soften brilliance
Grey: Cool undertone, can mute sparkle
Blue: Rare undertone, sometimes perceived as icy

Growth Lines
Formed during the lab-creation process, growth lines can reduce transparency and sparkle. Veralume evaluates and clearly discloses their presence.
Growth Line Scale
None: No visible lines under 10x magnification
Slight: Faint, minor effect face-up
Moderate: Noticeable, may reduce transparency/ sparkle
Distinct: Prominent, reduces brilliance and effects beauty
