What to look for

The 4Cs at a glance

Full Guide
Cut

The biggest driver of brilliance — more important than any other C.

Sweet spot: Excellent / Ideal

Color

Body color from icy (D) to faint yellow (Z). Most settings hide the difference.

Sweet spot: G–H (white gold) · I–J (yellow gold)

Clarity

Inclusions visible at 10× magnification. Eye-clean is what matters.

Sweet spot: VS2 — or SI1 if verified eye-clean

Carat

Weight, not size. Watch the price cliffs at every half-carat threshold.

Sweet spot: 0.90–0.95ct looks like 1.00ct for 20% less
