The 4 Cs, certification and current market factors together set value.
1 carat = 0.2g = 100 points. Price rises exponentially with size.
D–F colorless, G–J near-colorless, K–M faint, N–Z noticeable, plus fancy colors.
FL through I3 — from flawless to visible inclusions.
Proportions, not shape, drive brilliance — and 15–20% of value.
A GIA report adds confidence and value, but isn’t required for our evaluation.
