Carat Weight: 0.30 ct

Your 0.30 Carat Heart Lab Grown Diamond weighs 0.30 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.

Learn more about diamond carat weight.

Cut Grade: Ideal

Your 0.30 Carat Heart 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.
