Diamond Grading - The 4 Cs
Carat Weight
Measured in carats (1 carat = 200mg). Larger diamonds are rarer and more valuable. We offer diamonds from 0.5ct to 50ct+.
Color
Graded D (colorless) to Z (light color). D-F are colorless, G-J near colorless, K-M faint color. Higher grades command premium prices.
Clarity
Ranges from IF (internally flawless) to I3 (included). FL, IF, VVS1, VVS2, VS1, VS2 are premium grades. Fewer inclusions = higher value.
Cut
Evaluated for proportions, symmetry, and polish. Excellent, Very Good, Good, Fair, Poor grades. Better cut = more brilliance and sparkle.
