Carat Weight: 0.33 ct
Your 0.33 Carat Marquise Lab Grown Diamond weighs 0.33 carats. Carat measures a diamond's weight, not its physical size — two diamonds of the same carat weight can look different in diameter depending on cut and proportions.
Cut Grade: Ideal
Your 0.33 Carat Marquise Lab Grown Diamond is cut to Ideal standards. Cut determines how well a diamond's facets interact with light — the better the cut, the more brilliant and fiery the stone appears.
Color Grade: Black
Your 0.33 Carat Marquise Lab Grown Diamond features an exquisite Black hue. Fancy colored diamonds are celebrated for their vivid pigmentation and rare character.
Clarity Grade: VVS2
Your 0.33 Carat Marquise Lab Grown Diamond is graded VVS2 Clarity. Clarity measures internal and surface characteristics called inclusions — grades range from Flawless (FL) to Included (I1–I3), and most inclusions at VS and better are invisible to the naked eye.
Independent Certification
Graded and certified by IGI, the world's leading authority on fine jewelry diamond authentication.
Microscopic Laser Inscription
The girdle bears a microscopic laser inscription of its unique report number, visible only under 10x magnification for foolproof provenance.
